Episode Introduction
00:00:01
John
Good morning and welcome to the business of, almost said manufacturing, business of machining episode 428. My name is John Saunders.
00:00:09
johngrimsmo
And my name is John Grimsmo.
00:00:12
John
Taper lockups, new computers, budgeting, reporting, Johnny Five, robots, anything's fair game, right?
00:00:19
johngrimsmo
Yep,
Topics Overview
00:00:20
johngrimsmo
exactly. I also have taper lock angle, ah stress relieving, current stuff, hard milling stuff, Marv stuff, and watchmaker stuff.
00:00:29
John
Okay, we're 29 seconds in.
00:00:30
johngrimsmo
ah yeah We got a lot to do here.
00:00:30
John
Let's get through it all.
00:00:33
johngrimsmo
It's actually a nice little preview for the show. I like that.
00:00:36
John
Yeah, right? Because some of it's like, actually, some of it selfishly I want to talk to you about, but some of it's also kind of by like, what are you interested in hearing me? you know although Yeah, I know, right?
00:00:45
johngrimsmo
uh all of it don't that all sounded great
00:00:47
John
Probably. Well, here,
Upgrading to New Tech
00:00:49
John
I'll cut off. I'll check off a quick one, which is I was getting all these annoying Windows messages about Windows 10, end of life-ing, and then, yeah, don't know.
00:00:57
johngrimsmo
yeah i don't know what to do with that anyway go
00:00:59
John
Yeah. reminds me of the meme when it's like the Microsoft pop-up. It's like, how likely are you to recommend a Windows 10 to your friends? And it's like the response like, I need you to understand that we don't talk of like even nerds don't talk about operating whatever.
00:01:13
John
um punchline i looked i was like oh wow my desktop is way older than i realized um annoyingly it doesn't show me the processor when you go to your about your pc so i don't know what chipset's in it i'm assuming it's an i7 16 gigs of ram uh a two gigabyte nvidia 4p 2 620 graphics card um but it's no old one this is like a probably six year old type computer um
00:01:33
johngrimsmo
this your new computer or your old one? Okay. yeah
00:01:40
John
And it's perfectly fine, but when I do the big Johnny Five model, when I do lots of Fusion simulation, when I'm trying to screen record with Fusion, it is tough. So I was like, John, it's okay, get a new computer.
00:01:52
John
um Local guy is ah runs a real computer store, but he's always taking care of us really well.
00:01:57
johngrimsmo
Nice.
00:01:57
John
So the specs that got delivered yesterday were a... AMD Ryzen 9 9950X 4.3 gigahertz. He said some i9 chips are worth avoiding. So he's like, if you want the 9, go AMD. um i Look, I just, I trusted him. So great.
00:02:17
John
32 gigs of DDR5 RAM. And then a g NVIDIA GeForce RTX 5060 16 gigabyte graphics card.
00:02:29
John
Um, everything else is kind of normal, whatever, not worth mentioning. I think, you know, SSD, extra USB ports built into the motherboard itself.
00:02:35
johngrimsmo
Nice.
00:02:36
John
Um, And the fun thing was it, he dropped off at three o'clock yesterday. I did an hour's worth of installs at the shop, including setting up my remote desktop.
00:02:47
John
And then from home, I was able to do the rest, like Google Drive, Fusion, um printer apps, like all the little stuff. And I'm, as of this morning, just like it's done. um And it is so, it's fresh air.
00:02:57
johngrimsmo
Nice.
00:03:01
johngrimsmo
Yeah. Is it, do you notice it faster or it's different?
00:03:04
John
It is blazingly faster.
00:03:04
johngrimsmo
Obviously it's cleaner. Really? So my main laptop on the shop floor that I use for most things when I'm not at home is probably eight years old.
00:03:08
John
Yes.
00:03:16
John
Oh, John.
00:03:16
johngrimsmo
think it's like 2017, 18 kind of thing.
00:03:18
John
Yeah, right.
00:03:19
johngrimsmo
and it's And it keeps ya yelling at me for the Windows 10 thing. And it says, this computer is too old to update to Windows 11 or something.
00:03:24
John
president
00:03:26
johngrimsmo
And I don't really know.
00:03:26
John
Yeah. Yeah.
00:03:27
johngrimsmo
i don't understand the security concerns. And is that bad if I don't get security updates? Probably. It is an older computer. So I don't what I'm going to do yet.
00:03:36
John
Yeah.
00:03:36
johngrimsmo
Yeah,
00:03:38
John
The other thing I've changed is i've remote into this main one almost all the time now. So even my shop floor computer and my home computer, I don't use them anymore. i just remote into this computer from them.
00:03:48
johngrimsmo
yeah. yeah
00:03:49
John
So I was like all the more reason to actually get this one down pretty good.
00:03:53
johngrimsmo
Nice.
00:03:54
John
And then it's also nice cause you're not, you're not switching fusion sessions and yeah.
00:03:57
johngrimsmo
and Just leave it open on the one computer. Yeah, I do that quite a bit.
00:03:59
John
yeah But like looking scrubbing through so like either in-process stock or just fusion cam simulation, like you open up a simulation, you start dragging the mouse. It's just like, give me more. I'm like caught up.
00:04:09
johngrimsmo
No way.
00:04:11
John
Yeah, it's awesome, John.
00:04:11
johngrimsmo
Yeah, I tend to wait, you know, 10, 20, 40, 60, 90 seconds to like for the simulation to show what I need.
00:04:17
John
Yeah, right.
00:04:20
johngrimsmo
um Interesting.
00:04:22
John
And it felt good because the Don's my guy's name. He was like, look, some of these graphics cards were four times this more a couple years ago because of the whatever, either Bitcoin or ai surge. He's like, they're way more reasonable now.
00:04:33
John
So it felt good if you're spending 300 bucks, 500 bucks on a graphics card, at least it's not, you're not paying three times a markup because of some hyper surge.
00:04:39
johngrimsmo
mm-hmm well cool what do you have on the willy
00:04:41
John
um So that was a great quality of life improvement. And then bought a UR10 robot. Yeah.
The Role of Robotics in Manufacturing
00:04:50
John
E. Sorry. sorry
00:04:50
johngrimsmo
you are five okay so this is a bigger one you are ten is the not the biggest 16 is the biggest but or
00:04:56
John
They just, so I bought a 10E to clarify, um not a 10, that's just a generational upgrade, but the 10Es have much, much better force sensing stuff that is pretty important.
00:05:05
johngrimsmo
okay is this older newer does it matter
00:05:05
John
21, I bought used one. It's but not that old though.
00:05:11
johngrimsmo
Okay.
00:05:13
John
And again, it's um it's easier to find the 10s, not the 10Es that are, again, depending on what you're doing with it,
00:05:13
johngrimsmo
Yeah.
00:05:22
John
what we understand in our research research, we do not want a 10 full stop. So we bought the 10 E. They just like, i don't know, two months ago released a whole new line. They're going back to just like you are XX number schemes, not the E, but they're now, they don't have a 10 anymore.
00:05:31
johngrimsmo
Really?
00:05:35
johngrimsmo
Okay.
00:05:37
John
It's, I don't even remember eight, 16, 20, um, different lengths, different capacities. Um, To be fair, they do look better. They have fewer parts.
00:05:48
John
Like I'm sure there's other improvements, but they're not, our integrator was sort of like, they're not totally ready for prime time. And, um you know, we paid not a little more than half for a used one and it will do what we need it to do.
00:06:00
johngrimsmo
Yeah, it's huge.
00:06:00
John
And that matters to me big time. So it is going to um Idaho, we're using lights out manufacturing. They're going to get a bunch of stuff kind of wired up for it and so forth.
00:06:13
johngrimsmo
Cool.
00:06:14
John
And then We are shopping right now for a three axis to put it on.
00:06:19
johngrimsmo
Nice. not No plans for a fourth axis or fifth axis table or anything.
00:06:25
John
Don't need it. Don't want it.
00:06:26
johngrimsmo
Perfect.
00:06:27
John
Yep. Keep it simple.
00:06:29
johngrimsmo
I like it.
00:06:29
John
Yep.
One-Piece Flow Manufacturing
00:06:30
John
And I also, I'll go into it more in the future. i think, cause I am, i don't want to say I'm addicted and hooked. It's like another level beyond that of,
00:06:41
johngrimsmo
yeah what
00:06:42
John
how much I'm excited for one piece flow with probing inspection. Like on the URs you can use here. um now I'm going into it, but you can use the UR robot to grab the piece of stock and just push the stock up against a hard another hard stock.
00:06:57
John
It will measure it within, some number of thousandths of an inch, which means, yep, which means now you know your stock size, which you can either number one, validate your stocks correct, or number two, we do get saw cut stock.
00:07:00
johngrimsmo
what
00:07:08
John
It varies. We're now going to load three different programs that are posted that with, if the sum of the stock is it's oversized normally, if it's oversized with 50,000 more, if it's oversized by 100,000 more, we just load the program that best suits that stock, John.
00:07:12
johngrimsmo
oh
00:07:22
johngrimsmo
I think we've all been there with a piece of Sokka at stock that's, you know, 100,000 longer on the end. and you align it on your vice on the side, and then your end mill berries on the end or whatever.
00:07:29
John
Yep.
00:07:33
John
Yep.
00:07:34
johngrimsmo
That is, real I didn't know it could force sense and measure a nominal distance.
00:07:39
John
Well, think about it. It knows where it is
00:07:40
johngrimsmo
It makes sense.
00:07:42
John
Rotate at 180, and then it doesn't even matter where it grips it um ah within reason of of balance.
00:07:46
johngrimsmo
dude yeah that's sick yep
00:07:48
John
but um So, you know, D-mags, post-cleaning, inspection, probing, laser, fiber laser, so potential CMM work, putting every 20 parts, you put one in a three d printed bin that tells you what to check it for special, for batch checking.
00:08:04
John
um Camera system that's going to monitor that throughout the night. So when it does fail, because it will fail, we will learn. We can look at like all this stuff, John, has me... um
00:08:13
johngrimsmo
yes
00:08:13
John
You know, you and i talked about like our ebbs and flows of excitement in in this world ah industry and you people have probably heard.
00:08:17
johngrimsmo
yeah
00:08:19
John
I'd rather be honest about it. don't want to be, i don't want to sound like I don't want sound like I'm in, what do you call it I don't want to sound like i'm sad or like lost my motivation, but it does ebb and flow.
The Interferometer Project
00:08:30
johngrimsmo
yeah yeah totally that is amazing oh that's awesome yeah i've spent the past week uh since we talked last week obsessed about the white light interferometer
00:08:30
John
um I'm firing on all sellers right now.
00:08:35
John
Yeah.
00:08:44
John
Oh, yes, sure.
00:08:45
johngrimsmo
and And building that. So I've been building out my design. forget if I told you, but I'm going to be attaching it to my Zeiss microscope.
00:08:52
John
Yes, you mentioned.
00:08:52
johngrimsmo
And using yeah using the Zeiss just saves me a lot of time and money.
00:08:53
John
Mm-hmm.
00:08:56
johngrimsmo
Although it makes the design more complicated to attach it and adjust it and have it all perfect and stuff. but
00:09:01
John
Okay.
00:09:01
johngrimsmo
that's fine um so i'm i'm picking away at it i'm not rushing it i don't need it now but i want to do it right and i want to know that it's worth it and every day that goes by i i have a part in front of me or in my hand or i wish i wondered how deep this scratches or this pit and i'm like man if i had the white line interromeda i'd be done on this right now
00:09:12
John
Mm-hmm.
00:09:24
johngrimsmo
So it further validates my excitement and interest in that whole world of seeing deeper than 50 times Meg and knowing what's really happening.
00:09:35
johngrimsmo
um It's going to be a dangerous, you know, nothing's ever going to be good enough at that point, but that's okay.
00:09:38
John
Oh, that's true.
00:09:41
johngrimsmo
I can deal.
00:09:43
John
Yeah, that's awesome. joe i even your, well, what was your, in supposed showing the Hacksmith serial number with the Kern versus Speedio? That was just a microscope.
00:09:54
johngrimsmo
The
00:09:55
John
That wasn't
00:09:57
johngrimsmo
yeah that was just an optical microscope and it was actually their picture that I just reposted.
00:10:02
John
Yeah, that one's good.
00:10:04
johngrimsmo
Yeah, yeah.
00:10:05
John
that's That's child's play though, I guess.
00:10:05
johngrimsmo
but That's that's nothing. Yeah, that's like 10 times zoom.
00:10:08
John
Okay.
00:10:10
John
Oh, it looked more legit. Okay.
00:10:12
johngrimsmo
It looked pretty good. yeah i got to ask him what microscope that was because it seemed pretty nice. um But yeah, yeah. So that's kind of my super fired up thing lately is that.
00:10:25
John
What's the, oh, sorry.
00:10:26
johngrimsmo
No, what do you got?
00:10:27
John
Can you, without sharing more than you want share, you're not getting too, what's the, like, do you need to figure out what to buy? Do you just need to buy an assembly? Is there a risk about like, this is even going to work? Like, where are you on this project?
00:10:40
johngrimsmo
I'm after learning a lot, reading a lot of papers, watching a lot of YouTube videos. There's not a lot out there on them. Um, Cyrus has kind of the best DIY videos on them, which is great.
00:10:47
John
Yeah.
00:10:50
John
Mm-hmm.
00:10:50
johngrimsmo
And I've now hung out with him. We talked about it. I need to finalize, which I need to buy a beam splitter. I need to buy a reference mirror. Um, I kind of know which ones I need to buy and buying them used and cheap and they're not, they're like 50 bucks each kind of thing.
00:11:06
johngrimsmo
um Not a lot of money. I need, i want a motorized ah slide, just a single axis slider that all it really has to do is move at a very consistent speed to scan the fringes up and down the part.
00:11:20
John
Interesting. Sure.
00:11:21
johngrimsmo
um And I found there's this insane YouTube video from Diffraction Limited, where he made a micromanipulator.
00:11:28
John
Okay.
00:11:30
johngrimsmo
And it's a little three axis CNC machine that only has like a one inch working zone, but it will move to nanometer precision. And it's all open source.
00:11:43
johngrimsmo
And so I looked at his model and I'm like, I need to take one of those axes and with the encoder that he built himself for magnets and like a $5 sensor. And I'm like, and I need to apply that to my interferometer because awesome.
00:11:58
johngrimsmo
um So that's probably, I'm getting into that scope creep side of it where it's like,
00:12:04
John
yeah
00:12:05
johngrimsmo
You know, well, maybe I should just build his entire micromanipulator because then I'll understand his code better and then I can apply it to my thing and all that. And I'm like, what do I really want here?
00:12:15
johngrimsmo
All I really want to see is white light fringes perfectly accurately.
00:12:18
John
Yeah.
00:12:19
johngrimsmo
Okay. Step back. Okay. Take a breath. Um, yeah. So the slider and controlling that motor and Python scripts and all that, that's probably going to be the bigger hassle of time and effort.
00:12:32
johngrimsmo
Um, because I'm not super strong on like controlling servo motors, encoders, Python input data, all that stuff, but I'll figure it out.
00:12:43
John
But that, but that, I'm now to come back to this thing, theme I've sort of self and made of like, how often am I using chat GBT? I'm not using it every 20 minutes. Like,
00:12:53
johngrimsmo
Yeah.
00:12:54
John
Like I remember when Google, a podcast mentioned that Google, um, at corporate, I believe did like a red alert alarm. Like they've never done one in their corporate history. It's like, have they, have they come across it in a technology that represents an existential risk? And apparently with chat GBT or the, you know consumer adoption of LLMs, which certainly I think chat is the most, I believe the most used, but i don't care what you use it.
00:13:18
John
um And I've now completely, I don't search on Google anymore, unless it's for shopping or like movie tickets or something like itinerary stuff, travel stuff.
00:13:22
johngrimsmo
Yeah.
00:13:28
John
um And like, even just, you know, kind of actually to kind of steal from ah what Dylan does on with intolerance of like, what have you been You know, what have you been browsing?
00:13:39
johngrimsmo
yeah
00:13:40
John
yeah You know, I asked a question about the expected wear of my truck break. This is all the last two hours. Viewing network viewing existing network credentials ah for shared drives on an old computer so I can port them over a new one.
00:13:51
John
um Looking at equipment ownership structure information. How do I, I block websites on my work computers for myself to just because I, you know, what we talked about last week, like I need to, I don't need to look at the news every 20 minutes.
00:14:03
johngrimsmo
Yeah, yeah. but
00:14:05
John
It doesn't, just don't. Speaker recommendations for Johnny five is screen pal. So the best recording software auction sites for machine tool. Like I'm now in every single, Oh, G68 examples showing the the actual trig.
00:14:20
John
And it did all these for me. It built a, it created a Python script for a Fusion 360 model for a correctly designed speaker enclosure for Johnny 5, where you just import the script up into Fusion and it parametrically built the model.
00:14:34
johngrimsmo
No way. That's phenomenal.
00:14:36
John
Yeah, i like I'm Google's, I just don't use Yeah, so I figured why I start.
00:14:39
johngrimsmo
Yeah, I'm finding it's funny because because Meg hates like with a passion as a historian and all that stuff.
00:14:42
John
Oh, you're built.
00:14:48
John
I hear you. Sure.
00:14:49
johngrimsmo
So we we have interesting conversations because I'm like, I'm sorry, babe, I kind of like using it like um but I'm definitely finding limits where it is flat out wrong or misleading or um kind of puts me down the wrong rabbit hole that wastes a lot of time.
00:15:03
John
Exactly.
00:15:03
johngrimsmo
And you've got to really watch out for that, um obviously. But yeah, everything you just said, i i have my own list of of things like that that I use it for. Not every 20 minutes, but like at least every day, if not many, many times a day, especially when I'm doing a deep dive on the interferometer project or on what is a beam splitter or how does it work?
00:15:22
johngrimsmo
Or like, what is the difference between a confocal and a blah, blah, blah?
00:15:23
John
exactlyically
00:15:27
johngrimsmo
And just like all these things, just like tell me the answer. you know And and i will I will digest if it's kind of working or wrong.
00:15:32
John
yep
00:15:35
johngrimsmo
or And then I can further Google it. um to find real websites that I kind of validate and trust and things like that. But it's just like, just get me started. Or when writing scripts, just give me the script and I'll prove that works.
00:15:48
johngrimsmo
And wow, it works.
00:15:48
John
Well, that's point. you It can't not work because you'll, you you like, you yeah exactly.
00:15:52
johngrimsmo
Yeah, you'll prove it. But that's the difference.
00:15:54
John
We're we're obviously not doing human and surgery here. Like...
00:15:57
johngrimsmo
That's the difference with information and and you know facts in air quotes is it's sometimes harder to validate when it tells you something and you're like, oh, cool. But it's not like a Python script that you can be like, it's not working.
00:16:10
johngrimsmo
You know what i mean? Like subjective things.
00:16:12
John
I understand, and this this will quickly get way outside the purview of our relatively focused podcast, but I take issue, not with you at all, but with the main with with mainstream media, things like, for example, liberal organizations that are like 782,000 people died of COVID.
00:16:27
John
I made that number up, but it's like, no, they died with COVID. That guy died that guy got hit by a motorcycle.
00:16:30
johngrimsmo
Mm-hmm.
00:16:31
John
like He did not die from COVID. So my point being, not to be right or left, but rather there's lots of, there's more bias in all forms of media, whether you're on MSNBC or Fox News than I think we exist.
00:16:40
johngrimsmo
Yes.
00:16:45
John
And I know that's not analogous to ChatGBT telling you, you know, Tiananmen Square didn't happen or whatever, you know, rewriting history in a completely wrong way.
00:16:53
johngrimsmo
Yeah.
00:16:55
John
But the gain for for what I'm seeing, you know, is well worth
AI's Impact on Work and Learning
00:17:00
johngrimsmo
Yeah.
00:17:00
John
it.
00:17:00
John
It's just to explore and learn.
00:17:02
johngrimsmo
yeah as As long as you keep your um observant hat on and not just blindly trust everything it says, obviously.
00:17:10
John
Yeah. The stuff on the speakers, like I know, ah wish I wish I knew more about audio, but it's like, okay,
00:17:14
johngrimsmo
Yeah.
00:17:17
johngrimsmo
You kind of don't care.
00:17:18
John
Well, I like told it what driver i'm or amplifier I'm using, which is a PCB, like it's a DIY amp type thing, or it's a, you buy it off Amazon, but like, it's not a, this isn't like consumer shelf electronics.
00:17:21
johngrimsmo
Yeah.
00:17:28
johngrimsmo
Mm-hmm.
00:17:31
John
This is an actual circuit board. And then it's like, okay, for that one, you really want the forearm, not the ATOM. You want a sound box that has enough room here with a pastor here. You want to do this filter to help meet with the other speaker you told me you're using using in this robot. And it's just like, this is great. Like,
00:17:46
johngrimsmo
yeah
00:17:46
John
Maybe it's hallucinating, but I'm probably way better off than I would have been trying to read through forum posts or whatever.
00:17:53
johngrimsmo
exactly yep and another one that i've been dipping in and out of is i want to measure vibration like on a spindle or on a tool holder or imbalance or things like that and having deep conversations with chat gpt about it uh you can buy like a one dollar piezo sensor
00:18:02
John
Mm-hmm.
00:18:11
johngrimsmo
um which is like a little speaker kind of thing and it'll it'll measure the vibration and produce a voltage and then the the question i'm asking you now is do i buy like an 800 oscilloscope that measures four channels and all this thing or can i use all these raspberry pi's that i already have and is there a way to input the signal into raspberry pi and see signals and stuff and it told me things like if your vibrational frequency is higher than you know megahertz or kilohertz or whatever you need the oscilloscope because raspberry pi is limited to so many blah blah
00:18:14
John
Mm-hmm.
00:18:23
John
Oh.
00:18:41
johngrimsmo
And I'm like, cool.
00:18:41
John
Bingo.
00:18:42
johngrimsmo
Like, okay, that kind of helps. I should just buy the oscilloscope. And then if I need more functionality or different, I can build the Pi version as well. um But if, you know, for what I want to use, the oscilloscope is the right answer.
00:18:55
johngrimsmo
I'm like, sweet.
00:18:56
John
It is awesome.
00:18:57
johngrimsmo
Or if I went with the Pi route, it would tell me all the code and all the scripts and all the programs to download. And I find Raspberry Pi is confusing in a way where it's like, just tell me what to type into terminal and hit go and i don't need i didn't I don't need to memorize all this stuff.
00:19:11
John
Yeah.
00:19:13
johngrimsmo
Just tell me what to do.
00:19:15
John
Yep.
00:19:17
John
It's awesome. i mean i There's a part of me that has a huge amount of respect for humanity and cultures and education. So I i i don't know Meg's position.
00:19:29
John
I suspect I'd like to think there's a part of me that's very sympathetic to it. And certainly the issue of LLMs being trained over the next year or two on data sets of LLM-created content is a pretty frightening feedback loop.
00:19:41
johngrimsmo
Yeah, yeah, for sure.
00:19:44
John
I also think the cat's out of the bag. You can't unring this bell.
00:19:48
johngrimsmo
Totally.
00:19:48
John
And um sorry, you know, if you own if you own a bunch of horses, you don't like Henry Ford.
00:19:49
johngrimsmo
Yup.
00:19:54
John
But the reality is we're never never looking back.
00:19:56
johngrimsmo
Yeah, exactly.
00:20:00
johngrimsmo
Yup.
00:20:01
John
So what's next, like literally next step on just buying parts for the interferometer getting stuff in?
00:20:04
johngrimsmo
i'm I'm finalizing my 3D print design, which is getting more and more complicated. And what I need slash want is every optic component. I want it to magnet in place on a three-point kinematic mount.
00:20:15
John
Oh, face.
00:20:16
johngrimsmo
And I need multiple degrees of adjustment because these are all light and lasers and stuff. And you need to be able to aim everything to hit your camera lens perfectly.
00:20:24
John
Mm-hmm.
00:20:26
johngrimsmo
So I need a tip tilt adjustment. And I did a bunch of research on Thor Labs and it's like,
00:20:30
John
Yeah.
00:20:31
johngrimsmo
How do you, you know, you have three points of contact, you can have three adjusters, but you can also get away with just two adjusters. And one of the points is a pivot.
00:20:38
johngrimsmo
And that's how all the Thor Labs ones do. They only have two adjusters. that's like, well, how does that work? Oh, obviously. With three points, you can adjust your overall height because you just unthread them all.
00:20:38
John
Okay.
00:20:49
johngrimsmo
With two points or a one fixed point and two adjusters, you can only adjust tip hilt.
00:20:49
John
Okay.
00:20:54
John
Yeah, sure.
00:20:54
johngrimsmo
which which is fine from my application, but I also need a rotational adjustment as well. So I have to put it on a swiveling base or something like that and put an adjuster there. And then I need this to magnet in place on a kinematic mount.
00:21:06
johngrimsmo
So I want the beam splitter to come on and off and I want the LED assembly and the reference mirror to be able to just pop on and off.
00:21:14
John
Cool.
00:21:14
johngrimsmo
um so that's the design that i'm working on right now and then once that's done the print is it's complicated to attach everything together but the print will be easy the assembly should be easy it'll probably be wrong and i'll find out once i put it all together and then i'll make a tweak do another one um the stepper motor i can actually use like the smallest step or more like a nema 8 or something i don't need a nema 23.
00:21:28
John
Yeah, sure.
00:21:35
John
Yeah. All right.
00:21:37
johngrimsmo
um even though the guy's diffraction limited model is based on a NEMA 17. But I'm like, because I'm hanging all this from a 3D print, I kind of want as little weight as possible.
00:21:47
John
Sure.
00:21:48
johngrimsmo
And I already have this little, what's it called? ah seven millimeter linear rail.
00:21:52
John
Mm-hmm.
00:21:53
johngrimsmo
like from an old 3D printer project that I have and I'm not using. So i'm like, sweet, that's going to be my slider. And the motor is just going to slide that. And so the hard costs are like less than $100 in optics, beam splitter reference lens.
00:22:07
John
Isn't that crazy?
00:22:08
johngrimsmo
And like, it's just the the knowledge of putting it all together, the software side of it, the scanning side of it. um And I'm making it more complicated than it absolutely needs to be. So I'm like, Do I simplify this and just like start getting results before I build this whole complicated package?
00:22:24
johngrimsmo
um Anyway, so I'm on the 3D print right now.
00:22:27
John
Cool.
00:22:27
johngrimsmo
Kind of taking my time, but very
Sharing Personal Projects
00:22:30
johngrimsmo
fun.
00:22:30
John
Yeah. It's awesome. Are you going share about it when you like video or more or keep an
00:22:35
johngrimsmo
i Okay, here's where I'm at with that. I'm sick of hiding all the cool things that I'm working on.
00:22:42
John
Yeah.
00:22:43
johngrimsmo
And it's it's bugging me a lot. The problem is it takes a lot of time and effort to share all the cool things you're working on. And it's so much easier just to not. However, I would love to, and I want to.
00:22:57
John
OK, yeah.
00:22:57
johngrimsmo
So I will be filming the build of this um for YouTube video and probably a bunch of little Instagram things. I'm just, i don It's very easy to not share, but it's it's very cool when you do.
00:23:09
John
We had a nice compliment guy I was talking to um and he said, Hey, just so you know, I, and this is just one data point, but still very much appreciate.
00:23:21
John
He's like, I don't ever find you talking about something like tool path offensive or salesy because <unk> you've kept your points to being on topic. And by the way, he's like, I want to hear how people like you are using AI, like it will change our word.
00:23:28
johngrimsmo
Yeah.
00:23:32
John
I don't even, mean I'm not even bringing this up because of the whole AI thing. i'm just saying like,
00:23:34
johngrimsmo
Yeah.
00:23:35
John
I, it was nice to hear somebody says like, Hey, don't, you know, have to agree with you, disagree with you. I just want to see how you're using tools, technology, whatever is available. Um, and I think that's one reason why we do this.
00:23:46
John
Like I learned I'm better off because of what I see from you.
00:23:47
johngrimsmo
Yeah.
00:23:49
John
And it's iron ironic because I'm trying, am consciously cutting down a lot of my social media stuff. So you won't get some of the benefit of what we've seen.
00:23:55
johngrimsmo
Right. and
00:23:56
John
But the truth is that don't take this wrong way, but guys like you aren't putting that stuff out there anymore. And it's more you noise so i don't you know what mean like 100 but the caveat is that the the algorithm punishes you i don't i don't care like as a personal like i sleep fine at night my life's great except you you know don't
00:24:04
johngrimsmo
Yeah. Yeah. But maybe that's a perfect reason for us to need to share the more real, the meat and potatoes of these the cool things we're working on. I'll give you the real feed, not just the noise that everybody else is pumping.
00:24:23
johngrimsmo
Hmm.
00:24:30
John
you're playing the wrong game. That's the, my criticism.
00:24:31
johngrimsmo
Yeah, yeah.
00:24:32
John
So, um,
00:24:33
johngrimsmo
And maybe we got to look at it not as playing the game as we're just putting it out there. ah you just The information's there if you want to find it.
00:24:38
John
I know, I know.
00:24:40
johngrimsmo
And I find myself watching 32 minute very boring videos about white light interferometry that have very few views. And it's just like the greatest video I've ever seen. Yeah,
00:24:51
John
so Totally. And again, i know i've I've said Robin's name a lot like on this podcast recently, but it deservedly so.
00:24:55
johngrimsmo
yeah. yeah
00:24:57
John
Like I hope Robin never doesn't post a video and I've certainly.
00:25:00
johngrimsmo
Exactly.
00:25:01
John
Yeah.
00:25:02
johngrimsmo
that That is exactly the point I told my guys yesterday. i was like, you know, um imagine all the people that you, that you follow on Instagram, that you really enjoy their content. Like you're there for what they post. You never get sick of them posting too much. You want them to post more, even if it's a brand, like, like how many Porsche cars are in your feed? And you're like, yeah I want to see a next one. I want to see another one. Sure.
00:25:21
johngrimsmo
Like it's what you're, it's what you like to a point.
00:25:22
John
Yeah.
00:25:26
John
Yeah, but...
00:25:26
johngrimsmo
Um, um,
00:25:26
John
I'm sorry.
00:25:31
johngrimsmo
Which brings me to ah segues into another point. um One of the DMs that I got yesterday was ah I reposted a customer's picture where they took a part of a knife and they showed the inside of the knife.
00:25:42
johngrimsmo
Cool picture of a Norseman just showed the lock bar insert and it was colorful and beautiful.
00:25:44
John
Mm-hmm.
00:25:46
johngrimsmo
And so this watchmaker DM me and he's like, at first when I saw the picture, I thought it was a beautifully decorated watch bridge, like part of the movement in the back of the watch that was like, oh, and then I realized it's a Grimmswood knife and all the meticulous machining. It's like, okay, cool.
00:25:59
johngrimsmo
So he DM that to me. And then I was like, nope, not yet. And he's like, wait, are you thinking about making a watch? i'm like, yeah, of course I'm thinking about making a watch. um So I was at home in front of my desk and I don't even know if I've told you this, but going back to the whole, I'm sick of not sharing things.
00:26:16
John
Yep.
00:26:17
johngrimsmo
I'll start now.
Exploring Watchmaking
00:26:18
johngrimsmo
So for the past five months, you might've caught a little wind of it, but I've been totally obsessed with watchmaking. Yeah. on a far deeper level than i've ever like, than you even are aware of.
00:26:30
John
Okay.
00:26:30
johngrimsmo
It is, it is, no, it is, it is so deep.
00:26:31
John
I knew you were good, but obviously you're, it's more, it's,
00:26:34
johngrimsmo
So this guy's like a real watchmaker. His entire feed is his schooling and his watchmaking and the courses he's going through and all that. Like, that's what this guy does. And so I, I saw the DM I'm right in front of my desk at home and I filmed a video of that desk for him.
00:26:50
johngrimsmo
And it's a mega actually founded on Facebook marketplace. It's a late eighteen hundreds watchmakers desk with about, you know, 50 little tiny drawers and all this beautiful stuff.
00:26:57
John
any Okay.
00:27:02
johngrimsmo
And so we bought it and we refinished it. And now it is my computer desk at home.
00:27:06
John
Oh, that's awesome.
00:27:07
johngrimsmo
And I told her at,
00:27:08
John
So can i can you rewind? I'm following, but you lost me. Like this is the DM is from this watchmaker guy.
00:27:11
johngrimsmo
and sorry. Yeah.
00:27:14
John
You already own this desk, but you haven't shown it on your Instagram or what's the, okay.
00:27:14
johngrimsmo
yeah Yes. Correct. So I just sent him a little video because I'm like, he'll appreciate this.
00:27:22
John
Yeah.
00:27:22
johngrimsmo
And I kind of alluded that maybe we'll make a watch one day. And I'm like, No, dude, you don't know how far down the rabbit hole I am. Like, let me tell you. And so I took a little video of the desk. And it's cool. And not only that, but I've been buying all of the watchmaker tools for home.
00:27:37
johngrimsmo
um
00:27:38
John
Oh, that damn labe.
00:27:39
johngrimsmo
Exactly. And so I've got ah you know all all the screwdrivers and all the lubricants and all all the tools to service vintage watches um I now have.
00:27:41
John
OK. This is
00:27:48
John
awesome.
00:27:48
johngrimsmo
And I have this cell at home, which is like so amazing outside of work. It's not Fusion. It's not anything. It's just I don't even play a show or a video when I'm servicing a watch. I just I just do it for like hours at a time.
00:28:02
johngrimsmo
um And it is super, super enjoyable.
00:28:03
John
this is awesome
00:28:05
johngrimsmo
And so that's been my kind of secret obsession. um And not only that, but I've been to probably 50 antique stores this summer looking for vintage watches.
00:28:13
John
ah what ah You've shared some of that.
00:28:17
johngrimsmo
I've shared some, but 50 is a lot.
00:28:17
John
I picked up my... Okay. And so are you servicing them as a service to other people now, or are you just kind of doing something you're...
00:28:23
johngrimsmo
No.
00:28:24
John
Okay. Just for fun.
00:28:24
johngrimsmo
A, I don't feel like I'm nearly qualified to do that yet.
00:28:25
John
Okay.
00:28:29
johngrimsmo
um I'm doing it for fun. I'm doing it to learn and I'm doing it to learn in a very practical hands-on way how watches work, how they go together, not just theoretically, but like, no, no, I need to like lose screws and like search on the floor for an hour and tell my kids not to step on them until I find this little tiny screw.
00:28:39
John
yeah
00:28:46
John
but
00:28:47
johngrimsmo
And
00:28:48
John
Yeah.
00:28:49
johngrimsmo
i've I've been making small screws for 10 years, and I am still shocked at the level of tininess of a watch screw. it is It is mind-blowingly, ridiculously, dumbly small.
00:29:01
johngrimsmo
And it's really cool.
00:29:03
John
John, this is awesome. I mean, I guess as your, I don't know, like day job counterpart, counter like guidance to each other, there's some cautionary tale here, but like a hundred percent love it.
00:29:13
johngrimsmo
Yeah.
00:29:16
johngrimsmo
now,
00:29:16
John
I get it. Like,
00:29:17
johngrimsmo
Yep. And it's interesting because I'm doing it on my own time with my own money.
00:29:22
John
yeah.
00:29:22
johngrimsmo
um And it's like it's like a home project. And it's it's for now, it's for me, for John, not for Grimsbo Knives, not for...
00:29:29
John
I'm shit.
00:29:30
johngrimsmo
It is for the long term. If we're going to make watches, we're going to do it right. We're going to do it under the company and all that. But I'm just starting with, this is me time.
00:29:38
John
That's awesome.
00:29:39
johngrimsmo
Yeah.
00:29:40
John
Love it. Certainly don't mean to to even roll like Tommy Top, but I i feel the pack. Go ahead.
00:29:49
johngrimsmo
I have one last point on that. So this watchmaker I'm talking with, and the reason I brought it up here on the podcast is he said, not going to lie, I i went to watchmaking school in 2019 because of John Saunders and John Grimm's most YouTube videos.
00:30:02
John
That's awesome.
00:30:02
johngrimsmo
you guys inspired me into manufacturing and this is the route of manufacturing I took.
00:30:03
John
Yeah.
00:30:05
johngrimsmo
And i was like, shut up. Like, this is all full circle. Like in that time, now you've become the watchmaker and I'm aspiring to become a DIY watchmaker.
00:30:10
John
Yeah.
00:30:15
John
Yeah.
00:30:15
johngrimsmo
And right it's like, wow, cool. Like I'm never going to go to school for watchmaking. I'm never going a certified official, whatever. I don't care.
00:30:21
John
But you
00:30:23
johngrimsmo
I'll figure it out.
00:30:24
John
You're, well, there's like an aspect of, and i don't know Zach Smith super well, the current guy, actually you're in Ohio, but like, or I, associate with him, Kurt, but like he's his own entity, like very much in the watch world.
00:30:29
johngrimsmo
Yeah. Yeah.
00:30:34
johngrimsmo
yeah
00:30:36
John
And I believe, and then, yeah, Hakko has a little bit of a rebel aspect to their story. So dude, full love it.
00:30:43
johngrimsmo
Yeah.
00:30:43
John
Freaking love it. Yeah.
00:30:45
johngrimsmo
Yeah. it's cool.
00:30:47
John
and All I wanted to share was I had found a similar invigorating passion
Johnny Five Project Progress
00:30:50
John
with Johnny five, like,
00:30:51
johngrimsmo
Yes.
00:30:51
John
Just to out of, I took him home. It was the best move ever working on them on my own with my kids. Like when I want, and I constantly have to remind myself it's okay if you don't make more progress than you want to make.
00:31:02
John
Like, it's just, it's just for for you.
00:31:03
johngrimsmo
Yeah, exactly. Yep. Yep.
00:31:07
John
and I hope that bullet point sinks in. If there's folks that are listening that are in similar stories, like I, I really have to put a lot of effort into reminding myself, just, just smile and enjoy it. And I'm proud of what i built.
00:31:18
johngrimsmo
Yeah.
00:31:18
John
Um, and not think, oh man, I really need to get three things checked off the list. Also fun fact, like there are so many, ah there's 080 screws, there's a lot of 256 screws, like a 440 screw now looks big to me.
00:31:32
johngrimsmo
Yeah.
00:31:32
John
Now I know that's not watchmaking world stuff or even your knives, but like I grew up in, you know, Saunders Machine Works is like half 13 stuff.
00:31:34
johngrimsmo
Right.
00:31:38
John
Like, you know, think of a car with a half 13 screw.
00:31:39
johngrimsmo
Yeah, exactly. Yeah. Sorry, our knives are full for you.
00:31:44
John
Yeah.
00:31:45
johngrimsmo
The threads on the knives. um But
00:31:46
John
Does that look big to you?
00:31:48
johngrimsmo
And now it does after looking at the watch stuff.
00:31:50
John
Yeah, pretty funny.
00:31:50
johngrimsmo
Yeah. It's like ridiculous. You can fit, you know, 40 watch screws inside the surface area or the volume of a, one of our knife screws.
00:31:55
John
Yeah.
00:31:59
johngrimsmo
Um,
00:32:00
John
It's crazy.
00:32:01
johngrimsmo
Yeah. So, I mean, I've spent the past 10 years kind of grinding on Grimsmall knives and I work at work and I work at home and I do, it's like work and family. That's all I had for the past 10 years.
00:32:14
johngrimsmo
And this, this year I've finally allowed myself to spend a little bit of money personally and spend a lot of time personally on this kind of passion project and it's like i keep joking with my eyes like it's like honey i have a hobby now this is weird this is kind of cool like i've never needed to spend money at home on personal things just because i i have work things i i get to i get to buy all the cool tools at work
00:32:37
John
yeah right. Right. like
00:32:42
johngrimsmo
But home money, I don't spend home money.
00:32:43
John
Yeah.
00:32:45
johngrimsmo
I don't even spend a lot on clothes or tech or anything.
00:32:48
John
Yeah.
00:32:48
johngrimsmo
um But now it's like changing. Yeah,
00:32:52
John
Yep. Oh yeah. I like a Shaublin Collet for my birthday.
00:32:56
johngrimsmo
yeah exactly, exactly.
00:32:59
John
No, that's awesome. So the little lathe is at home, the one you bought on in.
00:33:01
johngrimsmo
it's It's currently at work. i got to rebuild the motor or have the local motor shop.
00:33:04
John
Okay.
00:33:05
johngrimsmo
like re I don't know, 50 bucks, I couldn't turn it down. I was like, sweet.
00:33:09
John
but Sorry, I should have asked the better question. That's for watch stuff. That's not for. Okay.
00:33:12
johngrimsmo
I don't know yet. We might use it at work instead um for polishing little things. We we don't have we don't have a manual lathe at all.
00:33:20
John
Vivor makes a very nice lathe for polishing things at work, John.
00:33:21
johngrimsmo
Yeah.
00:33:24
John
I'll have you know.
00:33:25
johngrimsmo
I thought you mentioned on the spencerer ah Spencer Web Podcast that your last lathe is going out the door very soon. And then I realized you have the V-Bor lathe.
00:33:32
John
It is.
00:33:35
John
Oh, come on. That's a low blow. You're right. But it's in the air. like Damn it. Oh, I sworn twice on this podcast. This is going to get flagged.
00:33:42
johngrimsmo
Oh, missed the first one.
00:33:43
John
um
00:33:43
johngrimsmo
Interesting.
00:33:45
John
Yeah, that's funny. Well, i will I will take the opportunity to mention, yes, our ST20Y is up on our Saunders Machine Works website.
00:33:47
johngrimsmo
Anyway.
00:33:54
John
So for folks that weren't interested, we're taking the approach of like very public about specs, price and all that.
00:33:58
johngrimsmo
Good.
00:34:00
John
yeah other But what I also have realized now, and this is gutsier and way different approach than I was originally planning, we're selling the horizontal.
00:34:08
johngrimsmo
The Okuma.
00:34:08
John
And yeah, so I was going to wait quite a while to mention this because I was thinking we would get the new machine in that we haven't bought yet, robot automation. But I've now um have so much conviction with humble confidence that that's the route we're going to go that I I'll mention it now in case, you know, it'll.
00:34:25
johngrimsmo
Yeah,
00:34:31
John
that machine it's not super unique or specific but it's definitely ah a big i mean it's a four millimeter akuma horizontal with a 217 tool atc and a six pallet pool so it's a very standard configuration if if you will but it's also it's not a vf2 like it's not like one of those like there's a hundred buyers at any point in time for that machine
00:34:44
johngrimsmo
yeah which is good. you
00:34:51
John
um So it'll it'll be some effort to sell it is of what I'm saying. But if for some reason someone listening and thinks interested, it will be months before we're ready to part with it. But I'd be happy to start having those conversations or have someone come out here and look at it, et etct cetera, et cetera.
00:35:01
johngrimsmo
Absolutely.
00:35:04
John
Yeah.
00:35:04
johngrimsmo
Yeah, it seems like a horizontal is sort of the thing, like when you're outgrowing three axis verticals and you're like, no, I need i need production. i need I need a machine that runs and runs and has a lot of tools and pallet changer and big parts, heavy parts.
00:35:15
John
Right.
00:35:16
johngrimsmo
um I'm curious, of the 217 tool, tool changer, what is your fill rate generally? Like like how many tools you got in there?
00:35:23
John
It's a little over a hundred.
00:35:25
johngrimsmo
Okay.
00:35:26
John
Yeah.
00:35:27
johngrimsmo
Better than if you if it only had 60.
00:35:27
John
but The incremental cost is, um so you, there's a, like a, i don't know, 30 or 60 tool changer. There's another wine rack option.
00:35:38
johngrimsmo
Wait.
00:35:39
John
Basically as soon as you go up to the external spider, it's effectively the same exterior sheet metal to go up to 50,
00:35:40
johngrimsmo
Yeah. right
00:35:48
John
free or 400 tools. And so the cost to go to add 50 tools is like they charge you a couple grand for like the wine rack sheet metal, but it wasn't like you.
00:35:56
johngrimsmo
yeah Yeah. Not much. Yeah.
00:35:58
John
Yeah.
Strategic Production Shifts
00:36:00
johngrimsmo
Yeah. Once you're there, you're in for a penny and for pound code thing.
00:36:00
John
Yeah.
00:36:03
John
a Thank you.
00:36:03
johngrimsmo
Um, okay.
00:36:05
John
but It's a great machine.
00:36:05
johngrimsmo
So
00:36:06
John
I have nothing wrong with it. And we make it's running this very second and we will it's also it's just we're going a totally different direction with production techniques.
00:36:09
johngrimsmo
Yeah.
00:36:13
johngrimsmo
Which is fascinating. And it's it's kind of a power move on your part. Like I know over the years how generally happy you've been with it. um Every machine has little problems and hiccups and like broken sensors and stuff. Every machine will do that.
00:36:26
johngrimsmo
But yeah, every time it's running well, you're like, it just runs. Like, I'm so happy with this.
00:36:31
John
Just of.
00:36:32
johngrimsmo
But I respect your direction change. And I can't wait to see where it goes.
00:36:37
John
Yeah, I know. Me too.
00:36:39
johngrimsmo
Oh, this guy.
00:36:41
John
Well, the other thing too is as much as I love the horizontal and look, it got us through production of the last few years that we would have never been able to keep up with, with standard three axis workflows.
00:36:42
johngrimsmo
Yeah.
00:36:52
John
But also I was so anti-robot. Like I really was.
00:36:56
johngrimsmo
Yeah.
00:36:57
John
And in the complication complications of part loading. So I don't have ah as succinct of an answer as to what changed other than the the benefits and um understanding you are frankly AI and the ability to like write scripts and and then recognizing what we want out of production and um And then the Willemann, which is a one-piece flow machine. So this is this whole thing is also very Willemann-ish inspired in that way.
00:37:23
johngrimsmo
Yeah.
00:37:24
John
It's a whole bunch of things like that that I like. um and And I guess the closest thing um that that triggered it was we were at that point where we really needed to start kind of doubling up fixtures on the horizontal.
00:37:26
johngrimsmo
Yeah.
00:37:36
John
And it's like, I don't want to make... You know, you just kind of listen to yourself. It's like, no, we can make these.
00:37:41
johngrimsmo
Yeah.
00:37:41
John
I don't want to make...
00:37:43
johngrimsmo
I'm, I'm kind of there somewhere way too.
00:37:44
John
16 or 24 more hardened eighty two fixtures that all behave differently that work offsets and crash risk and behavior.
00:37:45
johngrimsmo
Yeah. Yep.
00:37:50
John
And, um, I don't want to do this anymore.
00:37:53
johngrimsmo
That is exactly why Mori has not evolved in like the past seven years.
00:37:58
John
Yeah.
00:37:59
johngrimsmo
Because we still have we still have two orange vices on there with aluminum machined top pallets that bow and buckle and are not stable and are just bad.
00:37:59
John
yeah
00:38:08
johngrimsmo
And I went down the rabbit hole of, I had these A2 subplates made, heat treated, machined, surface ground, nickel plated, and we never used them. um And I was going to like put a whole bunch of modular devices on there that I could do smaller pallets, but it's still like, it's just a lot of work.
00:38:23
John
Yeah.
00:38:26
johngrimsmo
And obviously manufacturing is hard and it's work. But if, if from a point forward, you can make solid decisions that make future work easier, for example, like you're going thinking of a park loading there's no fixtures there.
00:38:41
John
Mm-hmm.
00:38:42
johngrimsmo
Like once you have a template, it just does the thing.
00:38:44
John
Yeah.
00:38:46
John
Well, there's, there there's, there's pictures, but it's one fixture. And so now like if I'm troubleshooting, it's top jaw, we can sit there and we can make one at a time. We can watch it. We can troubleshoot it. There's one toolpath.
00:38:57
John
There's like, you can pop like, it's so, there's so many yes moments to this.
00:38:59
johngrimsmo
Yeah.
00:39:03
johngrimsmo
Yeah.
00:39:03
John
Um, we're going to cut pads into the parts to do probing as, as checks and you don't have to run those.
00:39:07
johngrimsmo
Nice.
00:39:08
John
Like there's like, we started going through the, um and scott harms from metal quest kind of inspired me on this who's they've crushed it with robots it's like with a piece of paper right on every step you can think of like every single step that you want this to go through it's like pick up the material check the material open the door um and you'll some of them all end up being parallel processes or you'll add and delete but like you really think through every single little thing when do you open the vice when you even court in your inter interim was like hey instead of opening the vice then cleaning it why don't we clean it while the parts in it or minimize the risk
00:39:24
johngrimsmo
you
00:39:29
johngrimsmo
Sure.
00:39:39
John
Because the concern is when you're cleaning fixture A, you blow chips onto fixture B. And when you're cleaning B, you blow it back onto A. So it's like, how do you deal with
00:39:45
johngrimsmo
Sure.
Resolving Robotic Issues
00:39:46
John
it?
00:39:46
johngrimsmo
Yeah.
00:39:46
John
Anyway, I love it.
00:39:47
johngrimsmo
Yeah. And it really gets everybody thinking about the process because you're building the process. um was On that note, our robot, I mentioned it before, our Aeroa is acting up.
00:39:59
johngrimsmo
um It's not unclamping quick enough. So it's like when it unclamps the chuck and it lifts the Aeroa palette up, it it stays stuck and it kind of resists and it up, up, up, up And then it goes doing.
00:40:09
John
Ooh. Pops.
00:40:12
johngrimsmo
And it yeah, it's not great. So a few weeks ago, we took the chuck apart. We put all new O-rings in it because they had expanded and were just bad. It was the time to do it. That didn't solve the problem at all.
00:40:22
johngrimsmo
but We cleaned it.
00:40:23
johngrimsmo
We re-lubricated all the bearing valves, everything. I think there's another cylinder below that whole chuck that's like in the current Trunion thingy um that may maybe needs new O-rings and is getting slow.
00:40:23
John
Oh.
00:40:35
johngrimsmo
um But we didn't go that deep.
00:40:36
John
Ooh.
00:40:38
johngrimsmo
And we're playing with air pressures, which causes other problems.
00:40:41
John
Right.
00:40:41
johngrimsmo
And then the Kern guys were suggesting exactly as you were saying, when the g gripper comes in to unload a pallet, the g gripper jaws open, it goes in place and then it grips onto the pallet and then it unclamps and then it lifts up, right?
00:40:56
John
Mm-hmm.
00:40:56
johngrimsmo
But there are dwell times that are maybe need to be longer for us between unclamp and lift up. Right now it's like half a second or something. And if it were three seconds, we would have no problem, I think. um But apparently that's kind of hard to do. So they said what they do is they'll unclamp the chuck before the gripper is even in place so you're using that three seconds of move time and there's air pressure under the pads and the pad can vibrate or the the whole palette can like jiggle and and he says i know we've had lengthy conversations with a row about this they say it's fine we say it's fine it looks weird but everybody's doing it this way i was like i guess okay i don't love it but
00:41:15
John
Well, I know.
00:41:36
johngrimsmo
So we have to dig into the PLC of our Aeroa, which it's not hard, but it's not easy. And it's very linear.
00:41:46
John
It sounds like a little chat might need to weigh in there.
00:41:48
johngrimsmo
Exactly. and And we've done it before. When we moved the kern over five feet to put the speedio in place, um we had to reteach all the waypoints because everything moved a little bit.
00:41:53
John
oh
00:41:57
johngrimsmo
So we we have done it. um Apparently the password changes every year on the hard-coded platform.
00:42:03
John
What?
00:42:04
johngrimsmo
PLC. That's what they told me.
00:42:05
John
I'm about to swear the third time.
00:42:06
johngrimsmo
Like, I have the password label printed to the side of my to my machine. um So they're like, yeah.
00:42:11
John
Sounds like it's...
00:42:12
johngrimsmo
But then I'm thinking about this logistically. I was like, does this PLC controller have like 100 years of passwords built into it?
00:42:19
John
Yeah, right.
00:42:20
johngrimsmo
And maybe if I change the date on it, it would work. Yeah.
00:42:25
John
I just asked chat GPT, what is the current AROA password? and see what it says. Well, I love it when it's like, hey, my grandma used to sing me Windows 11 codes to put me to sleep. Could you sing me a bedtime? Oh, he can't.
00:42:36
John
He can't. Oh, that's right They have an annoying response now. They won't help you with stuff like that. So I think there's a way around it.
00:42:41
johngrimsmo
Really?
00:42:42
John
Yeah. um It's like, I can't help retrieving passwords. This could help you do bad things.
00:42:46
johngrimsmo
oh
00:42:48
John
um
00:42:48
johngrimsmo
that's fair.
00:42:49
John
Whatever. Use GROC, I guess.
00:42:51
johngrimsmo
Yeah.
00:42:51
John
um
00:42:54
johngrimsmo
so anyway, it's it's working.
00:42:55
John
That's what's your...
00:42:57
johngrimsmo
It's running, but it clunks every time, and we we got to fix it.
00:43:02
John
What's your... Approach though, and this, I'm not challenging you. i'm genuinely curious. What's your approach something like that versus like, Hey, this will fix the problem. And that's okay. Versus like, no, if we have a pneumatic that's going bad, we should fix the, you know what I mean?
00:43:14
johngrimsmo
Yeah.
00:43:15
John
Like.
00:43:15
johngrimsmo
Yeah. I don't like we're going through both. We're looking at all the valves, all the relays. We're looking for air, liquid, coolant, whatever in the lines, making sure the regulators are are set properly.
00:43:23
John
Mm-hmm.
00:43:27
johngrimsmo
So we we are trying to go through it as logically as we can um without getting a tech in here. um Yeah. And I don't love the bandaid because the bandaid, while it is a solution, there's still an underlying problem.
00:43:40
johngrimsmo
Like, why is this worse now than it was a year ago?
00:43:43
John
but and You run that machine for tens of thousands of hours.
00:43:44
johngrimsmo
Like a a lot.
00:43:46
John
like You know how it should behave.
00:43:47
johngrimsmo
Exactly.
00:43:48
John
Yeah, Yeah.
00:43:48
johngrimsmo
Exactly. And it's only going to get worse. Things like this, you know, like mechanical things only get worse. You can't just like crank up the air pressure and assume it'll be better. um So it's got to be take off the chuck, whatever ceiling piston um is under that.
00:44:06
johngrimsmo
I bet you the O-rings are just super swollen and sticky and no good anymore. And that's not a bad thing. um We just got to get in there, which I don't think is impossible.
00:44:16
johngrimsmo
I was just kind of scared of it when I had the chuck off.
00:44:18
John
Oh, is it? It sounded like the chuck on off could be a one day, two day project.
00:44:23
johngrimsmo
It is. And now that, now that I i have the Aurora calibration palette, I know how to align it. It's, it's probably a two hour project.
00:44:28
John
Yeah.
00:44:30
johngrimsmo
Um,
00:44:31
John
When you put it back onto, you could immediately check the release. So you kind of know what you're looking for to see, right?
00:44:35
johngrimsmo
yes, I think so. Well, no, cause if you, if you, if you manually release it, it doesn't always do it.
00:44:37
John
You can check that before you align it.
00:44:41
johngrimsmo
It just like, after it's been gripped for a while and, I don't know exactly when.
00:44:46
John
No, that's annoying.
00:44:46
johngrimsmo
Yeah.
00:44:47
John
But that's weird. That doesn't... Whatever. Yeah.
00:44:50
johngrimsmo
Yeah.
00:44:51
John
Well, we're quote-unquote out of time and we didn't even get to the taper lockup.
00:44:56
johngrimsmo
Let's do it.
00:44:57
John
Do it. Shoot.
00:44:59
johngrimsmo
ah
00:45:01
johngrimsmo
Let's see. So I had the guys make me a six degree included angle, seven degree and eight degree buttons. Did I tell you about this?
00:45:09
John
think you said you were going
Knife Performance Improvements
00:45:10
John
to...
00:45:10
johngrimsmo
Right. So we I've been stuck on six degrees because I'm like, that's how I designed it. And that's how it's got to be. And we'll make it work. And we're changing with surface finishes and all that stuff. So I'm like, you know what? Let's go. Let's go wild here. lets Make me a seven degree, make me an eight degree.
00:45:24
johngrimsmo
without even changing the blade, which happens to be 6.8 degree right now, the mating feature. um So I tried 7 degree and then I tried an 8 degree button in a 6.8 degree blade.
00:45:36
johngrimsmo
And it it is amazing. It is absolutely phenomenal.
00:45:42
John
Can you try to explain to me what is that? like only having one thin con like one tangentially radio contact patch. yeah
00:45:50
johngrimsmo
Technically, except everything is rubber, and the second the surface is kind of wearing together, one of them is going to give the softer one, the blade, um is going to conform to the button shape.
00:45:53
John
Yeah.
00:46:02
John
Okay.
00:46:03
johngrimsmo
And still, at the end of the day, since the button is so hard, we're locked on an eight degree angle. The blade is going to squish itself and kind of become an eight degree angle, which is ah broader than the taper locking angle or a locking taper.
00:46:16
John
That's what was trying to think through. So like, if I think about a funnel I'd use to put car on my oil, that's quite big. You have a, and that's the knife, your pin is not as tapered as it is.
00:46:22
johngrimsmo
Yeah.
00:46:27
John
So it's, there's a bunch of space around it versus it being overly.
00:46:31
johngrimsmo
Yeah, and I had to literally sit there with pen and paper and and fusion sketches and be like, what does this really look like?
00:46:34
John
Sorry. Yeah.
00:46:36
johngrimsmo
Where's it contacting?
00:46:38
John
Mm-hmm.
00:46:38
johngrimsmo
where's it What's going to deform? What's going to matter? And this whole process of developing this knife, I don't know. So I'm learning and I'm testing and I'm feeling it. But this 8 degree button in a 6.8 blade is working so good. There's no more button stick.
00:46:53
johngrimsmo
It just unclicks like super smooth and it holds.
00:46:53
John
Dude.
00:46:56
johngrimsmo
It holds to some abuse um keeping the blade locked. And I'm like, I think we got it. So the guys are currently machining couple hundred um ah eight degree buttons, and then they'll heat treat tomorrow.
00:47:02
John
Dude.
00:47:09
johngrimsmo
And then we have over 100 fields in process ready to put together waiting for buttons.
00:47:12
John
Nice.
00:47:15
johngrimsmo
um So that's fantastic.
00:47:19
John
And no issues, more issues on the ah button material?
00:47:24
johngrimsmo
We are on M2 right now, which is getting about 63, 64 Rockwell, which is fantastic. My only caveat is that it it is not a stainless steel. And long term, I don't love that.
00:47:33
John
okay
00:47:36
johngrimsmo
um I want this knife to still exist in 100 years kind of thing. like And if I can use a stainless, I want to use a stainless. so the one i've got in my knife right now is 420v which is uh apparently really good stainless should be awesome for what we're doing and i'm testing it right now and uh getting good results so yeah this one's coming in at 64 65 but these these are the ones that dent weirdly in heat treat so
00:47:55
John
You need it to be at north of 60 though, right?
00:48:00
John
Oh, wow.
00:48:04
John
But you fix that with the graphite, right?
00:48:04
johngrimsmo
I fixed it with the graphite exactly. So I'm i'm using the graphite heat treated samples right now as my testers and final validating, but it's not like a super easy material to buy.
00:48:06
John
Yeah. but
00:48:11
John
so
00:48:16
johngrimsmo
um I can't just like buy it on McMaster like I can the M2.
00:48:17
John
Oh.
00:48:20
John
Okay.
00:48:21
johngrimsmo
So that's kind of, I can get it.
00:48:21
John
But you can get it reliably. like
00:48:24
johngrimsmo
I think we have to get it through Germany and then import through the US, which is dumb for tariffs and then ground and then sent to us.
00:48:24
John
live Okay.
00:48:30
John
Yeah.
00:48:32
johngrimsmo
So it's a process.
00:48:33
John
Got it. Okay.
00:48:37
johngrimsmo
But yeah. Okay, your turn. What do you got
00:48:39
John
Well, all was going to ask you and it's half a question, half a statement, but I haven't shared as much with Johnny Five at home because he's kind of become my project. Like, it's not because don't want to share it, but like, it's just my,
00:48:48
johngrimsmo
you got? Yeah, right? Yeah, yeah.
Finalizing the Johnny Five Project
00:48:51
John
it's my time away.
00:48:51
John
I'm not like all this social media stuff. Like it's none of it is... business intent, sponsor, none of none of that, period. It's just my love of what I'm doing. And sometimes it's just fun to not worry about it. And at this point, he's so close actually to being done.
00:49:06
John
um Part of me is wondering, do I just go into quiet mode and finish him?
00:49:10
johngrimsmo
Yeah, right?
00:49:11
John
Versus versus the like, hey, I want attention for every little screw. I thought I'm being exaggerated. But like, here, John, take a look at this.
00:49:16
johngrimsmo
Yep. Yep.
00:49:22
johngrimsmo
Oh, I see 25. I see, is that LEDs under his neck or?
00:49:25
John
his His lip lights are moving, so his audio, as he talks, that the neck cylinders work, the head motion works.
00:49:26
johngrimsmo
Oh my gosh. And he's just looking around the room like a chicken head. oh my gosh.
00:49:34
John
um There's more that works that I'm not showing here on this.
00:49:35
johngrimsmo
How? Is that a programmed routine?
00:49:39
John
Yeah, right now it is.
00:49:40
johngrimsmo
Interesting.
00:49:41
John
Yeah.
00:49:42
johngrimsmo
I don't even know how all that is going to work out for you.
00:49:42
John
So
00:49:44
johngrimsmo
Like, yeah.
00:49:45
John
I didn't either. I'm learning. Um, and for the folks that don't see that video, I might put that up on social, but like, he's, he's really, he's really close to, uh, that's not to say there are lots of little things I will continue to improve on him, but, um, he really came along last 40 days.
00:49:52
johngrimsmo
Yeah, 100%.
00:49:55
johngrimsmo
Yeah.
00:49:59
johngrimsmo
Yeah.
00:50:04
johngrimsmo
That is fantastic.
00:50:04
John
Um, yeah. So I'm super pumped.
00:50:07
johngrimsmo
I think...
00:50:08
John
In fact, I, you,
00:50:09
johngrimsmo
I think the the answer for sharing is what is the lowest effort, highest yield or enjoyment from viewers that we can do? Like you posting that video with basically no context is like low effort for you, high enjoyment for everybody watching it, like win, epic win, you know?
00:50:21
John
That's all I do. Yeah. Yeah.
00:50:28
John
Well, I'll, I'll put that out to our audience. You guys know how to reach us through emails or Instagrams. If you guys want to see stuff from Grimsville on the infront, or from me on Johnny, cause like at this point we don't need the, I'm not doing it to feed my ego or attention. Like it's more about just passion and pride.
00:50:43
johngrimsmo
like
00:50:44
John
Um,
00:50:44
johngrimsmo
my business could use the eyeballs. I got to mention.
00:50:47
John
Oh, that's fair. Fine.
00:50:48
johngrimsmo
So there's that.
00:50:48
John
this part Sure. This podcast is sponsored by Grimstone Eyes and Saunders Machine Works. um Reach out to us. We'd be curious.
00:50:56
johngrimsmo
Yeah.
00:50:56
John
Yeah.
00:50:57
johngrimsmo
DM us. Let us know um if you want to see more. Obviously you want to see more, but you know, give us ideas.
00:51:02
John
Yeah.
00:51:03
johngrimsmo
i don't know.
00:51:04
John
Same thing with the robots. Like we're going to go through a steep learning curve with integrating a UR robot on One Piece Flow. Some of that will end up being secret sauce stuff.
00:51:14
John
I think that makes our business thrive, but it's also like, no, like, look, tons of people helped us.
00:51:18
johngrimsmo
Yeah.
00:51:19
John
Like I'm not, I'm not going to be your integrator, but like, I'm going to also and share some what we learned.
00:51:21
johngrimsmo
Yeah.
00:51:26
John
That makes sense.
00:51:27
johngrimsmo
I think that's one of my hesitations not to get too deep in the weeds here, but if I share a deep topic, I don't want to hold somebody's hand while they try to do it too.
00:51:31
John
Mm-hmm.
00:51:38
johngrimsmo
You know what i mean? like i'm I'm happy to help, but I got a lot on my plate and I don't necessarily want to feel 400 emails on how to integrate a UR robot into different machines.
00:51:48
johngrimsmo
um
00:51:49
John
Most people know, understand that now.
00:51:51
johngrimsmo
I know. Yeah. And it's maybe it's a mental barrier, not an actual barrier. Cause while I do get a good amount of DMS, not a ton of them are like super complex required big response kind of, you know, anyway,
00:52:06
John
right.
00:52:09
John
well I'll go out of my way and say, if you if you are going to reach out to anybody and you want help, help yourself first. Like I will my i will get a little pissy when somebody asks me a question that they could have Googled themselves immediately.
00:52:20
johngrimsmo
Yes.
00:52:21
John
Like you need to help yourself. But when somebody reached out they're like, Hey, I did this thing Utah. I've been doing it. I just can't figure out this one little thing. Like I'll usually respond with audio message for sure.
00:52:30
johngrimsmo
Which is really cool.
00:52:30
John
But I it all time.
00:52:31
johngrimsmo
I've never done that. I like that you do that. Yeah, that's really cool.
00:52:33
John
Yeah. Um, maybe that makes me a bit of turd, but I, I have a low threshold for people that are just lazy and just want you to help do the work for them.
00:52:41
johngrimsmo
Mm-hmm.
00:52:42
John
But if somebody else is really trying, yeah.
00:52:44
johngrimsmo
Yep.
00:52:45
John
Okay. Let's see what do. Anyway, I'll see you next week.
00:52:46
johngrimsmo
100% same. Okay, man. Sounds good. Take care.
00:52:50
John
Bye.
00:52:50
johngrimsmo
Bye.
