johngrimsmo
Good morning and welcome to the Business of Machining episode 413. My name is John Grimsmo.
00:00:06
John S
And my name is John Saunders.
00:00:08
johngrimsmo
And this is your weekly manufacturing dose where two business owners kind of hash out what's going on, what's new, what's changing, what's going good and what's going bad in their companies.
The Role of Conversations in Growth
00:00:20
John S
and I will share John and i honestly really do normally record everything, but you know, a while we'll have conversations that are kind of offline, which is healthy and good.
00:00:30
John S
And, um, I enjoyed, there's a lot to be said for kind of this existential, why do we do what we do? What do we want out of it on a very personal level, on a family level, personal finance level, business level?
00:00:42
John S
Um, it's good to have those conversations.
00:00:45
johngrimsmo
Absolutely. Whether it's a time in and out, um, money put in and money taken out.
Balancing Family and Business
00:00:52
johngrimsmo
Um, you know, as our kids grow, my kids are now, you know, 12 and 15.
00:00:56
johngrimsmo
Um, I, I go through phases in their past 15 years of like, they need me more. Okay. They don't need me right now.
00:01:04
johngrimsmo
And you know, and it, it flip-flops. Um, but the past little bit, they've needed more more and I've been around more and that, you know, pulls me away from the business a little bit. Um, But my business needs to be able to do that for me.
00:01:19
johngrimsmo
Like that's one of the reasons why i own a business is to have that slight flexibility to do what I need to do as long as I get my stuff done.
00:01:27
johngrimsmo
um And i'm I'm doing that. I'm, you know, towing that line right now where I can be quite flexible with my work schedule and be there as much as I need to be with my family. And it's going really well.
Business Setup and Obligations
00:01:40
John S
Yeah. But it's fun to talk, even if it's, you know, in, in confidence about, Hey, how do you set up these small businesses and are you borrowing money from machine vendors or from banks or from family?
00:01:50
John S
you have, do you investors? Well, how do you think about the obligations to yourself and to the business? And, um, that ties into stuff that I know you and i talked about some, but I'd like to talk about more of like, you know, is this a business that, you know, your two children would want to get involved in and becomes multi-generational is,
00:02:10
johngrimsmo
and Some of the deeper parts of these conversations, uh, do most people wouldn't be comfortable sharing publicly because it's, you know, like private stuff.
00:02:20
johngrimsmo
Um, and that's, that's fine. But do some of the questions, do we want this to last longer? Do I want my kids to get into it? Clara has no interest life. Maybe, um, he's talked about, he's 12.
00:02:33
johngrimsmo
Like he doesn't really know what he wants to do.
00:02:35
johngrimsmo
Um, he's he's at the age where he thinks he knows everything and he he will probably stay at that age. So he's about 30. But, um but but yeah, it's cool.
00:02:47
John S
I appreciate it makes me value, I mean, the but at this point, maybe thousands of hours, certainly hundreds of hours of back and forth.
00:02:54
johngrimsmo
Okay. Right. Okay. I'm going to math that out real quick. 413 times minutes minutes
00:03:03
johngrimsmo
by otherwise sixty is three hundred hours
00:03:05
John S
600, okay. Yeah, seems more, no, be more. Yeah, that would be right, okay.
00:03:12
John S
Huh. Yeah. What's going on? What's what's on your mind?
Technical CNC Issue
00:03:18
johngrimsmo
A lot of technical little issues keep me busy at work. I had an issue yesterday where, ah so our guy Steven runs the Speedio and he was hard milling our fjell blades, all little critical locking features on the fjell.
00:03:33
johngrimsmo
It's an 11 minute cycle. and angelo and i are having a meeting in the lunchroom um and steve walks in he's like did you put a couple more blades on the speedio no i haven't touched it all day he goes well it's still running it's been running for three hours and i'm like what ah go figure it out so he comes back later and he's like it's just looping the same program
00:03:57
johngrimsmo
So the way I have my subroutines set up and my macros and everything, it's, I got something wrong, obviously. So instead of hitting M99 at the end, it hit M, or instead of hitting M30, it hit And then it just rewound to the top and did it again.
00:04:12
johngrimsmo
And because I'm deprinting probed results on every blade, I was like, let me look at the results and see how many times we just reran this one blade. We ran it 17 times in a row.
00:04:22
John S
I'd say your spring passes are good.
00:04:24
johngrimsmo
Exactly. And fun fact, the bore diameter, which normally we're holding about one tenth, is ah just over a thou bigger. So it sprung past more and more and more and more.
00:04:36
John S
Interesting, that is kind of telling.
00:04:40
johngrimsmo
Yeah. Because because there's there's no more spring pass after 17 goes. um
00:04:46
John S
Yes, i but at least I hope there's not.
00:04:48
johngrimsmo
yeah So the question is, is that blade going to actually work? Because the hole is a little bit bigger and some of the locking features will be bigger. um ah we sent We sent it up to the finishing shop with a big fat sticky note on it saying these details and see John for more info.
00:05:06
johngrimsmo
um But yeah, that was kind of funny. And I still haven't actually solved it, but I'm going to do that next after this podcast. But
Toolpath Automation Excitement
00:05:16
John S
the I made my first toolpath part. So, ah
00:05:20
johngrimsmo
Like with the tool path software.
00:05:22
John S
yes. And there's like a ton of like, the watching toolpath automatically program part in Fusion is nothing short of magic.
00:05:32
johngrimsmo
You actually watch it happen. Like tool paths could create it or what?
00:05:35
johngrimsmo
What do you see? i don't know.
00:05:37
johngrimsmo
I've seen a couple little videos, but.
00:05:39
John S
Yeah, I mean, I just took, so a Johnny, do I have it here? thought I did. It's a Johnny 5 part, now that I don't know where I put it. And a very simple 2.5 axis part.
00:05:52
John S
But a great example is something where it's like, I don't want to program this anymore. It's right here. um And yeah.
00:05:57
johngrimsmo
So got flat part drilled and tapped holes face on top.
00:06:00
John S
Yeah. Yeah, simple hole, one big hole, a bunch of little holes.
00:06:04
John S
And you click a button and it just does all the tool pass. And then you go back into Fusion they're all there. Like it's just magic. So in this part, there would have been roughing, ah profiling, drilling, chamfering, facing, all that's just done.
00:06:20
John S
Now where it gets messy is number one, tools. How do you get your tools into tool pass? It knows what to use. And number two, tool pass. ah this This would have been an honest to goodness 10 out of 10 home run awesome. But when I did this last night at home and when I got to the shop, this is a quarter inch thick part. We don't really stock this thin of aluminum.
00:06:40
John S
And so I just grabbed a piece out of our scrap bin that was five eighths thick. and way bigger and I didn't want to saw it down. So I super glued this relatively oversized large part and I didn't want to adapt it all that away. So I sort of was counterproductive. I deleted the adaptive, switched it to a slot, like a 2D contour slotting.
00:07:02
John S
And so ah it probably was a wash. I wouldn't say it was slower to do it through toolpath, but it certainly wasn't the magic of like click and done and run run the code.
00:07:12
John S
It could have been if I had the right size material though.
00:07:12
johngrimsmo
Okay. Yeah, which is important. Yeah. Okay.
00:07:16
John S
Um, so that was, that felt good. Cause I do want to see, will very much want to see them succeed both because I think about what I've gone through in my years of doing this and how much more efficient we all could be. And I know this is on top of mind for you about, hey, how does your team make fixtures? how do you guys program parts?
00:07:38
John S
It's not necessarily ever going to be used for production parts where there's, you know, you've 260 tool pass in some of your parts. Sorry, John, but like when you want to make a quick fixture to hold a part, this kind of stuff makes it, especially if you have tool libraries and work holding type setup, which you do with your Auroa and Speedy and all that,
Innovations in Tool Selection
00:07:56
John S
I love. And then the other really cool thing, which is probably the most magical thing I've seen, certainly out of Toolpath and arguably in manufacturing in recent years, um there's a new video. I'll send you a link to it. It's quite short called the Toolpath Tool Recommendation Engine. It's 21 seconds.
00:08:13
johngrimsmo
I saw the repost you did. Yeah.
00:08:15
John S
Dude, it takes your part. um And right now I think they're tying in with Kenna Metal libraries. There'll be more in the future, but it takes your part. And it's just like, here are the four tools you'll need to do this. And now we're talking, we're not just talking like end mills, but like length of cut, ah dr like all this quirky stuff.
00:08:25
johngrimsmo
but the Okay, sure.
00:08:32
John S
So the holy grail will be an integration of your library plus the tool recommendation engine to be like, hey, John, you can do this part, but you need to order this key seat cutter.
00:08:43
johngrimsmo
Okay, got it.
00:08:43
John S
Here's here's a link to Kenna Metal, click here to buy it. um
00:08:47
johngrimsmo
Okay, that's cool. Yeah, especially key seat cutters and weird things that are like, you know, spent a lot of time measuring hole diameters.
00:08:54
johngrimsmo
How do I get a key seat in here? And like, interesting.
00:08:57
John S
Right. And obviously for those that are job shops and quoting you now with almost no effort, know a lot more about the cycle time and tooling costs, which, um, that we've heard, and I should disclose, I think I have before, so maybe I'll stop, but I'm an investor and board member.
00:09:13
John S
So I'm very much biased, but I'm only there because I saw the team and what they're doing.
00:09:16
John S
and I wanted to be involved.
00:09:17
John S
So it's, it's the the best of intentions from that standpoint. Um,
00:09:21
johngrimsmo
Yeah. And you have a very practical outlook on it. um You're not trying to blow smoke up anybody's butt, but you're, you're you do see the value.
00:09:29
John S
If anything, I've been a thorn in their palm because there's kind of this debate about like, and this is my own words, is Toolify this own software or is it just a really, really powerful addition to Fusion?
00:09:40
John S
um And there's more to that argument. I really want it to be a powerful addition to Fusion.
00:09:47
John S
the way I want to use it. I don't want to do my work holding in tool. I don't want to deal with like I'm a fusion user and we, we are, you are, that's where your stuff lives.
00:09:55
John S
So, um, I'm not saying I'm right by the way on that, but, um, that's kind of been the top of my, it's fun to see, it's fun to see where it goes.
00:10:02
John S
And like I said, there's enough magic to this technology that someone's going to crack this nut and much in the same way, none of us are writing G code.
00:10:12
John S
i think in two years, three years, uh, Cam is going to be something where you, um, CJ had a great quote, get get me 90% of the way there with
Future of CAM Automation
00:10:21
John S
I'm going to still, still going to be a form of skilled labor. I'm still going to need to tweak stuff massage that. That's fine. But the majority of it will will be, um, automated, which is freaking awesome.
00:10:31
johngrimsmo
Yeah. Cause the more parts you program, the more you realize how repit repetitive it is. um
00:10:39
johngrimsmo
And the fine tuning, even the fine tuning that I do is that finishing touch. It's, you know, the right tool, the right speeds and feeds, the right step overs, um the right strategies of even the order of operations sometimes really makes a big difference.
00:10:53
johngrimsmo
And that's where the skill comes in.
00:10:55
johngrimsmo
um But if you're just banging out parts.
00:10:57
John S
But I'm pushing them to do that. I'm pushing them to have that capability.
00:11:00
John S
I mean I don't want overpromise, but the the look, we could talk forever about this.
00:11:02
johngrimsmo
Kind of logic.
00:11:05
John S
The weirder things come in like, oh, like what happened today? I'm not holding this in a mod vice anymore. I'm super gluing it, which means I want to slot it.
00:11:13
John S
That's a very, in a perfect world, this is, again, to be totally clear, this is not something ToolPass going to do ever, if certainly in your firm. In a perfect world, you'd have a LLM like chat GPT in front of toolpath and you can say hey toolpath reprogram that part but I'm super gluing it now so will you back off my feeds and speeds and slot it but leave 20 thou on the slot like you could talk to it and then have it do it that's kind of the perfect world yep
00:11:44
John S
anyway I'll stop yeah Tormach
00:11:44
johngrimsmo
Well, that that's exciting. So like, you actually made you made the part. What machine you make it on? Nice.
00:11:52
John S
Yeah. Um, and that was the I don't want to sit here and get too excited, but I was excited. Like that's that we have a, we took our time. We built a good tool library on that machine with all the work holding set up for it.
00:12:04
John S
And so now when I want to make a part, it's just like, yeah, done. Like the hardest part was going to the scrap bin because it's like, that's a weird size.
00:12:11
John S
Um, and the super glue was there to do like, it was just, it couldn't have been more effortless. And that is a freaking win. Love that.
00:12:19
johngrimsmo
So trying to work through this in my head in fusion, like what is step one? You have a part modeled. Do you start a new file with your vice, your fixture, your part in it your stock, and then you hit go on the tool path.
00:12:34
John S
Uh, let's come back to that in a future podcast. Cause I don't know what's there's work holding stuff that's happening.
00:12:39
John S
I don't remember what's public and what's in beta or whatever, but for parts like this, where you don't really care about
00:12:47
John S
it's certainly not collision risk, three plus two, et cetera, et cetera. You just have your part. Like you click, set it to a path, pick the, it'll let you use their default tool library, which is a great way to reduce the burden.
00:12:58
John S
If you want to just see what it can do, you just programs your part. You're done in your, you can have G code to review in 30 seconds.
00:13:03
johngrimsmo
But how it's held and are there g gripper jaws on the vice? You don't want to hit them. There's a hat on the second op. Okay.
00:13:09
John S
That's what's coming in and um it's coming.
00:13:14
John S
That type of thing.
00:13:16
John S
Yep. Yeah. but from yeah
00:13:20
johngrimsmo
yeah, that kind of an issue we've been having the
Waterjet Cutting Challenges
00:13:23
johngrimsmo
past few days. And today, especially i was just talking with my guys about it. Um, so we get our blades, the rough blank of the blade. We get a water jet cut local company. We buy the big sheets of steel from dam steel.
00:13:34
johngrimsmo
Um, they come to us and it's our nice stainless steel oversized thickness. Um, and they're like two foot by three foot sheets, pretty much, um, five sixteenths thick or five 30 seconds, you know, 150,000. Um,
00:13:50
johngrimsmo
um And then we have a local water jet company. We literally drive it over. They water jet our parts. They come back. A bunch of the parts in this last batch, the holes are too small, which is kind of annoying because the screw won't go in.
00:14:03
johngrimsmo
um But the profiles are bad.
00:14:05
John S
From the water jet shop.
00:14:07
johngrimsmo
ah Either we don't know exactly what happened, but nothing's lining up well. um I think hole to hole spacing is probably OK. The holes are small, so we have to drill them out before a screw will go in, which is annoying.
00:14:21
johngrimsmo
And then one of the, um the, the jimping, so little grippy holes on the blade where the flipper tab is that kind of gives you grip on your finger.
00:14:32
johngrimsmo
We drill those with the one 16th drill bit and we ream them um one 16th as well.
00:14:37
johngrimsmo
And so we spot drill undersized and then ream to size. And that's supposed to be kind of 50 thou away from the water jet wall so that there's enough meat to like,
00:14:46
johngrimsmo
get in there. Um, but that drill is breaking and we've broken two or three of those drills now because it's hitting the edge of the material because the profile is small. Um, and these are like,
00:14:56
John S
I've never heard heard of like, do they have a linear or a ball screw issue or backlash or like what's a, it was weird.
00:15:03
johngrimsmo
I don't know, or the sheet shifted. Maybe that's one of our thoughts, you know, pretty easy for that to happen.
00:15:11
johngrimsmo
I could imagine a situation, imagine the water jet program. They're like, let me do all the holes first, 400 holes, and then go back and do all the profiles.
00:15:19
johngrimsmo
And there's a shift in the middle, like maybe, I don't know. um But that's us trying to triage this and trying to figure out what happened and then trying to figure out what do we need to bring back to the water jet supplier to be like, these are wrong.
00:15:32
johngrimsmo
I don't know why, but they're bad and we can't use them or maybe we can.
00:15:39
johngrimsmo
Yeah, I was just looking at flat bottom drills. like They do exist in 1 16 size, so I could actually just plunge that hole. there There is enough material to do everything, just not with our current strategy.
00:15:52
John S
Yeah, man, um for I'm sorry.
00:15:55
johngrimsmo
Yeah, it's it's just annoying.
00:15:57
johngrimsmo
And you think, oh it's just one. And then the guys are going through every blade. And they're like, well, these are all kind of vary. And you can kind of see it, some of it. um And then just today I printed off a DXF of the water jet file with little crosshairs in the holes. Yeah.
00:16:13
johngrimsmo
And the first one I printed, it's it's like small. And then I put the blade on top of this print piece of paper and i was like, why is it small? I look at the print settings within Fusion, it says fit to page.
00:16:24
johngrimsmo
i'm like, oh, dang it.
00:16:25
johngrimsmo
Okay, put it to one-to-one, print it again.
00:16:28
johngrimsmo
It's still small. I'm like, hold on. And I actually printed the hole to hole spacing, like the dimension 4.72, whatever.
00:16:37
johngrimsmo
So that I could take my calipers to the piece of paper and I could be like, no, this measures 4.55, not 4.72.
00:16:41
johngrimsmo
the heck? That's one-to-one printed. what the heck that's it's one to one printed So then I did the math between those two numbers and I'm like, okay, let me print one at a scale of 1.04, 628, whatever to one.
00:16:53
johngrimsmo
And now it's, you know, caliper paper bang on close enough. Um, and I'm like, what the heck? I don't know.
00:17:00
John S
you have a second printer to try?
00:17:02
johngrimsmo
ah yeah, probably, but I haven't done that yet, but it's, know.
00:17:06
johngrimsmo
I got the result I need. Now I have a piece of paper. We can lay the water jet on top and it shows, oh, we're missing in this area.
Handling Vendor Mishaps
00:17:12
johngrimsmo
Um, So yeah, the guys are thinking if we drill the holes off center, it might work. It might save everything.
00:17:25
John S
you just bore interpolating with a solid end mill?
00:17:27
johngrimsmo
Yeah, you'd have to.
00:17:28
johngrimsmo
and But some of my guys didn't get that far yet. I suggested that. I'm like, but then we got to hold it. We got to like, we have 300 parts here that we have to like hold. um Soft jaws would be a pretty easy soft jaws and a vice.
00:17:40
johngrimsmo
um Pretty easy way to do that. ah But we don't we don't do that. I haven't made soft jaws in like years other than no on the Willowman. um So yeah, it's 100%.
00:17:49
John S
I believe in you, John. you You can do this. You can make sure.
00:17:52
johngrimsmo
um Ideally, ah don't touch this whole project.
00:17:56
johngrimsmo
ah But yeah, Yes. Anyway, that's where I'm at. Oh.
00:18:00
John S
This similar-ish thing happened to us about a year ago and it had to do with buying some material that a spec got changed where it ended up going from um effectively hot rolled to cold rolled and they were stressing it and the mark the parts moved.
00:18:15
John S
I think we actually talked about this a little bit. and What I learned, which I don't mean to tell you how to do it anyway, how to to handle the situation, but I certainly am gonna learn a lot and took this to heart, which was, if this happens to us in the future, the first thing we're doing is we're ordering, like in this case, the material was the problem. So the first thing we're doing is we're ordering the correct material, getting it in, knowing that we can go back to making good parts from scratch.
00:18:41
John S
And that that process happens. Simultaneous to that, we'll decide, should we rework the stuff that we have? And then you start to size up, okay, it's X amount of money in the material and it would be this much more to work it and there's a risk about returns.
00:18:57
John S
I don't overanalyze this. I'm making it sound like I do, but I've always found emotionally, if it's, let's say it's $3,000 worth steel, the first thing you want to do is be like, ah no, we need to save all that and rework it.
00:18:59
johngrimsmo
yeah Yeah, I don't really care anymore.
00:19:08
John S
We can do it. We can figure out. And then once we get the new material and we start making good product, you look at that pile of bad material and you're just like, that good riddance, like, write but um yeah
00:19:19
johngrimsmo
But it it is easy to your point to get hung up on like, before moving on, like, I got to find the problem, I got to solve the problem, I got to fix all this material, and then I can move on. i get stuck in that sometimes for sure.
00:19:30
John S
Well, you do need to figure out for sure. i mean, what happened or tell the water jet folks to make them.
00:19:35
John S
Don't do like your point don't do all the holes at once and then go back to profiles. Do a full blade. um That way if it shifts, you're going to ruin a couple of blades at most maybe.
00:19:43
johngrimsmo
Yeah, exactly. Yep. So I'm in this mental battle of like, do I feed back to our current water jet supplier? Do I try to find another water jet supplier? um There's plus and minuses to all options.
00:19:54
johngrimsmo
You know, we've had other issues um from, mean, every vendor will give you issues just because our expectations are high.
00:20:01
johngrimsmo
And why can't you just do the thing? you know Just do what I asked.
00:20:06
John S
you have a Wazer now. You could test, test.
00:20:08
John S
cut what No, no, that won't work for production, but you could test cut one.
00:20:10
johngrimsmo
Not for production, but um but when Eric first started making dam steel blades on the Wazer, they also came out super undersized. But like <unk> it's, um you know, Fusion, you have the direction arrow like on this side or on that side.
00:20:24
johngrimsmo
But on Wazer, your curve is small and he didn't really know left or right. So he just made, you know, oversized holes, undersized profiles, which is the worst of both worlds, because now the whole part can shift in the hole.
00:20:36
johngrimsmo
And it's undersized. ah So he scrapped a couple of damn steel blades because of that.
00:20:41
John S
Can you fix the blaze on the laser?
00:20:43
johngrimsmo
ah Oh, that's a good question. I don't know.
00:20:48
John S
Waterjet might be perfect to be.
00:20:49
johngrimsmo
it It might. Well, Grayson's first idea was like, if we had a wire, that would be amazing. I think, yes, we we don't have a wire. Move on.
00:21:00
johngrimsmo
I'd love to, but um could you water jet them? Probably. You'd need a fixture to repeatedly hold them, and then it would just tickle the missing section.
00:21:12
johngrimsmo
Because i think we need to make a small um circular hole into an oval so that the blade moves um like in the fixture.
00:21:23
johngrimsmo
I don't know. A couple ways to do it, but...
00:21:25
John S
Hartman, saw and mill and the toolpaths also seems pretty nice because
00:21:30
johngrimsmo
Yeah, it's soft jaws and an orange vise seems really low effort.
00:21:34
John S
you're, yeah, right.
00:21:35
johngrimsmo
um and you just, there's only so many to do. i forget if it's a hundred or a bit more, maybe.
00:21:41
John S
Yeah, crank through and then, right.
00:21:41
johngrimsmo
Um, yeah. So there's that.
00:21:44
John S
Oh, I'm sorry, that stinks.
00:21:47
johngrimsmo
Yeah. It's annoying. Each drill is, you know, close to a hundred dollars. So we've lost two of those and you start scratching your head and you're like, hold on, we have a pattern here.
00:21:59
John S
so it's It's always tough with vendors that are performing a service that where the service cost is still relatively small compared to the material or value.
00:22:07
John S
You can't go back to them and say, Hey, you owe me all this. Like they're, they,
00:22:10
johngrimsmo
You can do a chargeback if you really push like either next order. I want so much off because you sent me so many bad parts in in your labor.
00:22:18
johngrimsmo
um Angelo worked in aerospace for many years and Jeff worked at automotive prototyping lab. So they both have a quite a bit of experience with what they do in the big companies for this.
00:22:30
johngrimsmo
And yeah, chargeback can be can be common. um Sometimes if the remote supplier scraps customer supplied material, you know the customer would be like, oh, you just scrapped $50,000 in material that I brought to you. You owe me $50,000. I don't think that usually works very well.
00:22:49
johngrimsmo
But in the effort and labor that that supplier put into your products, if they did a poor job, there is definitely a conversation there to have some flexibility, depending on...
00:22:57
John S
for but to your point it's not like they thought oh let's screw this batch up like it's probably an innocent mistake
00:23:02
johngrimsmo
Of course, of course. and And my guys are like, there's no way they didn't know that these were bad parts because they're they're visual. the If you look close enough, you can tell that they look weird.
00:23:14
John S
oh i'd be i'd be careful though john you're not putting on the bias how this is your world like there's a guy at the water jet shop who doesn't know you guys from a spider co
00:23:15
johngrimsmo
But how close are you looking? No.
00:23:23
johngrimsmo
Totally. I'm trying to...
00:23:24
John S
So on that note, and this, I got a tip of the hat to Henry Holsters because I'd like to think I would have thought of this on my own, but it's really touring his shop lately that got me thinking more about this. You need to send him, you need to send them ah green and red, go, no, go 3D printed template gauges where they, when they pull parts off the water jet, they just drop them in to make sure they fit.
00:23:47
johngrimsmo
Yeah, that's a pretty good idea because at that moment they can tweak hole sizes. They can tweak offsets. They can do a test cut. They can, they can get it right.
00:23:56
johngrimsmo
That's a good idea. I think we told them, you know, years ago, an M six screw has to pass through. um
00:24:04
johngrimsmo
But i I doubt that has carried forward to the latest guy doing the job right now. It might be on the print. I don't know. But there's something there.
00:24:11
John S
we've We've adopted this mentality of like, this might sound kind of weird, so hear me out, but like, we are never the victim.
00:24:18
John S
It's always my fault. So, you know,
00:24:21
johngrimsmo
Wait. so I got to get.
00:24:23
John S
I'm it's yeah, it's always something that I just always something we should have done better.
00:24:24
johngrimsmo
Yeah. which Interesting.
00:24:28
John S
So, ah and you kind of treat it to the lowest common denominator like, Hey, you get the, you know, night shift person that's running this.
00:24:34
John S
It doesn't know or care. Not a bad way they just don't know.
00:24:36
John S
So it's kind of like, how do you put it on the paperwork?
00:24:38
John S
How do you put it on the traveler? How do you instruct it with each shipment? How do you include the, you know, even for certain processes, we used to send them gauges now,
00:24:48
John S
We include the gauges in a with the shipment each time in clear box so that it's basically ah gross negligence. You can't possibly remove our product without seeing the gauge right there.
00:25:02
John S
with That's the mentality I have.
00:25:03
johngrimsmo
And I like that because we're delivering material on sheets of material. We could easily have either 3D printed or literally machine parts if you need a bit more accuracy and rigidity.
00:25:14
johngrimsmo
um And we could include that. And then it's there. And then it comes back to us. And then...
00:25:20
John S
Yeah, and it's like your phone number is on the 3D printed part, so that's like you call me when there's a question or you stop, like do whatever.
00:25:27
John S
You just make it idiot-proof.
00:25:29
johngrimsmo
Yeah, don I feel like 3D print wouldn't be... I don't want say accurate enough, but obvious enough for these small errors that we're seeing. But if it was, say you machine a pocket into a block of aluminum and be like, the part needs to slip into this pocket, but not be smaller, or you have a go, no go.
00:25:47
John S
Or 3D print with holes in and just buy McMaster pins and press them in for future sizes.
00:25:52
johngrimsmo
Yeah, yeah. Well, and because the holes are pretty easy to gauge, but ah they clearly didn't because they're all undersized. But everything else is weird, organic shapes. Like you can't just take calipers and be like, oh, that's one inch.
00:26:06
johngrimsmo
Nothing is measurable, really. oh
00:26:09
johngrimsmo
So even if you called out a bunch of arcs and angles on the print, like it's useless.
00:26:14
johngrimsmo
However, a physical hard, you know, slip on gauge, go, no, go. Great idea. Well, there's something there.
Johnny Five Project Update
00:26:27
John S
I got to bring up Johnny Five again.
00:26:29
johngrimsmo
obviously yeah it's insane
00:26:30
John S
Cause number one, it's awesome. We put an Instagram video. He's under RC control. Um, now I'm tearing into the upper torso sections, um, which is a mix of but far less to do, but also like, Oh my gosh, you just forget how many freaking things and parts there is. Like I spent 20 minutes last night, just looking through ah CAD model to find what I need to add to the McMaster cart so that you don't, um,
00:26:57
John S
end up 40 minutes into a specific area of the build and be like, i don't have a 1.25 inch flathead 440 screw. Like these are not Home Depot viable hardware stuff.
00:27:10
John S
um Which is a great segue to ah thing I've said before, but I, And I don't know if this is just, I'm the only person in the world afflicted by this. And if that's the case, I'm sorry for wasting everybody's time, but I still get overwhelmed. It's probably like a form of anxiety about the build. I want it done. I want to be proud of it. I get hard on myself. And then I just realize,
00:27:31
John S
like take a deep breath. All I need to do today is this one, you know, fist size section. Like I even brought a part in, like all I need to do is get this bearing pocket done with the screws in the side.
00:27:44
John S
And that's all you gotta worry about. Just one part, one step at a time.
00:27:48
John S
Um, maybe a humble analogy would be like, it's like building a car from scratch and it's just like, you know, and it's tough because you, oh, you to work on the suspension and then you realize you don't ball joint. That's two days away. So now you do, know, you have energy and time. So it's like, well, I'm going to go work on the, the differential because I have those parts sitting here in a box, which means you also have the box labeled. You need, know, there's some time to get back into that part and be like, okay, where I leave off, what do need to do next?
00:28:12
John S
Um, so it's been, It's still been very fun and I've just learned a lot about managing my own mentality behind the project.
00:28:24
johngrimsmo
I'm curious, since some of the other other stuff we talked about, ah do you have Johnny Five costed out?
00:28:30
John S
You don't want to know.
00:28:32
johngrimsmo
No, but I'm curious, are you costing it? Like, do you? No, I don't need to know what it is.
00:28:38
John S
But it's it's probably the closest thing to like, I just pretend to not. to the
00:28:44
John S
At this point, it's it's kind of like the Apollo program when they shut it down. Like they didn't run 18, 19, and 20. Like 98% of the project was funded, but the allowance was still a lot. Like last night, last last two days have been three-figure McMaster order, like hundreds of dollars in McMaster for like $1,
00:29:01
John S
you know, and sometimes it's annoying cause it's like, I need a 4.3, seven, five inch quarter 20 shoulder bowl or something.
00:29:08
John S
and it's like, they only sell them in 10 packs. It's 18. It's like death $18 parts.
00:29:14
John S
Um, but I'm also not gonna try to get a five inch one and go over to the delay, either grinder and sand it down.
00:29:20
johngrimsmo
Or you buy the one pack in a stainless steel bowl so that's, you know, $5 cheaper or something like that.
00:29:25
John S
yeah. Um, yeah, not for the faint of heart. Um,
00:29:32
John S
But like I gotta to say thank you to everybody. I've been trying to put some instances up of like, now that I'm tearing so much of them apart, showing off the folks that made parts and
00:29:38
johngrimsmo
Yeah, yeah. I saw that.
00:29:40
johngrimsmo
I really appreciate you re-showing that. and I'm sure all those people like like love that too.
00:29:45
johngrimsmo
um And to remind you know current viewers and myself included that a lot of these components were made by fans and friends um years ago.
00:29:56
johngrimsmo
And the you know beautiful work. And it's you have such a an amazing collection of a crowd-sourced, like friend-sourced machine parts for this Johnny Five.
00:30:06
johngrimsmo
It's it's beautiful.
00:30:07
John S
Yeah, it really is awesome.
00:30:12
John S
Last question I had for you. um We have three machines now that are frankly more idle than they are on the Tormach, the UMC 350 and our grinder. And the UMC got, yeah, the UMC got pretty close to having skank coolant.
00:30:23
johngrimsmo
The surface grinder? Yep.
00:30:29
John S
um To be fair, we just, the skimmer got unplugged. So that's probably part of it. But um I need to spend some time thinking about how to maintain coolant flood coolant machines where they may not get used for two, three weeks.
00:30:44
johngrimsmo
Do bubbler in any of them?
00:30:46
John S
Only in the grinder. And that was going to be one of my thoughts. I did that because I felt like somebody had said at one point time, but I don't know if that's good because it agitates it or because it oxygenates it.
00:30:58
johngrimsmo
I think both. I think it prevents the top skim layer of oil from just creating a a um seal.
00:31:07
johngrimsmo
on the top. So that's one of the reasons probably oxygenates the coolant a little bit and it kind of keeps it moving and flowing a little bit too.
00:31:13
johngrimsmo
um On the Mori, we actually have a small aquarium pump that pumps a hose all the way around to the opposite corner and then just flows coolant to, yeah.
00:31:22
John S
Oh, that's a great call.
00:31:24
johngrimsmo
So it's literally circulating the coolant and I think it runs 24 seven.
00:31:27
johngrimsmo
It also, it's the same, maybe the same one that goes through the coalescer.
00:31:33
johngrimsmo
Maybe it's not the same pump, but it's a similar thing. um
00:31:37
John S
I was thinking, Bubbler, the idea of a pump just to create some flow is a great point.
00:31:40
johngrimsmo
Yeah. You're kind of faking use, you know?
00:31:43
johngrimsmo
um It obviously provides a small flood risk if something goes wrong. Because, know, you have a new hose, but...
00:31:50
John S
yeah. So we do the bubbler and all the other stuff like that in our shop, our pond are well pump for our RO system, all that stuff is on Alexa timers and then none of it runs, which I like because I don't want the bubbler to run 365.
00:32:05
John S
twenty four seven three sixty five And then Alexa timer just...
00:32:05
johngrimsmo
Yeah. Yeah. I think ours does, but
00:32:12
John S
But not the bubbler so much as the, I don't want IBC toad of water getting dumped onto my floor i at two in the morning.
00:32:19
johngrimsmo
Yep. Yeah. hundred percent. Yeah. And our central cooling system, we've got a big green, big red e stop on the front of it that I'm pretty sure we shut it off ah like every, every day.
00:32:32
johngrimsmo
Cause we don't need it on when it's nobody's here.
00:32:35
johngrimsmo
Cause don't have auto fill at this moment, but we don't need it.
00:32:39
John S
Okay, so, because I was thinking stupidly about like ah an arm that just rotated, to like agitated, but of course, freaking aquarium is way, way smarter.
00:32:48
johngrimsmo
Yep. You just flow fluid. Yep.
00:32:50
John S
And you can even run that tubing in the coolant. So it's it's not like it's going outside the machine and if it ever popped a leak, that'll help.
00:32:54
johngrimsmo
Yeah. Sure. Yep. Yep.
Coolant Maintenance Strategies
00:33:01
johngrimsmo
Yeah, I think coolant doesn't like to sit still. um Bacteria is a thing. don't know.
00:33:08
John S
Is yours good when we're talking about a long time ago with the algae or something?
00:33:12
johngrimsmo
Um, mostly foaming was our problem. So we have 251C in most machines, except for the Mori. We're testing Geo Cool 890, I think. It's a quality chem product and it's made different. i don't know if it's a fully synthetic or if it's a vegetable based or something. It's, it's weird.
00:33:31
johngrimsmo
Um, it's certainly gotten a different aroma to it. And because it's a year, maybe close to two years old, it's starting to get like yellower.
00:33:41
johngrimsmo
You know, quality cam is like white. It's like when it's clean, it's like nice.
00:33:45
johngrimsmo
It's got that smell we're used to. And it's just, and this GeoCool is different.
00:33:49
johngrimsmo
It looks uglier, but it performs really well. And we had, we had massive foaming problems on that machine where it would flood a little bit almost every day. And now and nothing like now it just works.
00:33:59
John S
Okay. That's good.
00:34:00
johngrimsmo
So the question we're battling with is, do we swap the whole shop over to centralized with this new coolant?
00:34:06
johngrimsmo
And Angela and I, we don't have a decision yet.
00:34:10
John S
It's really nice to have one coolant.
00:34:12
johngrimsmo
Yeah. Yeah, especially because we have plumbing to pretty much every machine. um
00:34:17
John S
that's Cause you run premix through your lines.
00:34:19
johngrimsmo
Pre-mix through the shop, yeah.
00:34:21
johngrimsmo
Which is great. you have one tub in the back with a mixotron thing, and and it just pressurizes coolant to each machine.
00:34:29
johngrimsmo
But I don't know. we're We're at the point where we're pretty much out of coolant, like like ah concentrate.
00:34:38
johngrimsmo
So it's time to order something. And all the machines are pretty much due for a full changeover. So Angela's like, it's going to be a day to like change them all over and make a decision on which one.
00:34:48
johngrimsmo
And ah we have a Freddy, which helps.
00:34:50
johngrimsmo
But yeah, it's just work.
00:34:52
John S
What size, Freddie, you have?
00:34:54
johngrimsmo
It's huge. I don't know. It's not the little tiny vertical one.
00:34:57
johngrimsmo
It's the big, like, like drum size.
00:35:02
John S
We have an Xair, which I think was, don't know, actually don't know the technical differences in what it can do, but um I thought about adding a Freddy because the one we have 110 gallon drum with the idea that you can drain.
00:35:12
johngrimsmo
Mm-hmm. Which is big.
00:35:14
John S
Yeah. I wanted to be able to drain a whole tank, cool tank, but yeah,
00:35:18
John S
It had a 25 or 50 micron sock filter in it and the, they were cleaning a tank and putting it back in and it wasn't, I wasn't happy. So we bought a five micron filter and that worked, but it's like, ah, man, you don't always, i don't think we always want to be using a five micron.
00:35:35
John S
It seems like it's going to clog up pretty quick.
00:35:37
johngrimsmo
Clog up and or strip the defoamer out of the coolant.
00:35:39
John S
Yeah. Yeah. So part of me is like, man, you could almost benefit from having two. One's a rough filter, one's a fine filter, but now we're getting, don't know.
00:35:49
johngrimsmo
Yeah. Yeah. I've thought about buying a second small Freddy for our oil machines for the Willie and for the Swiss.
00:35:58
johngrimsmo
Not that we ever really do, like the oil doesn't really go bad, but sometimes we want to remove it all so we can clean the tanks and get all the little chips out and like just do a good clean. oh But that's money that doesn't need to be spent right now.
00:36:12
John S
Yeah, sure. I was a little bit surprised that I thought the Freddy's were, it looked like you could spend a lot more than I was wanting to spend on a Freddy.
00:36:20
johngrimsmo
Yeah, they're like a high four figures.
00:36:25
John S
Yeah, exactly. Which our Xair, maybe it's less, maybe it has less features. I don't know that guy I don't know, but it was two grand.
00:36:33
johngrimsmo
it's air operated, right?
00:36:35
johngrimsmo
Right. The Freddie has like pumps, so two pumps at least.
00:36:37
John S
Oh, I bet that's the difference, which I don't, I have no problem using air.
00:36:41
John S
Good grief. That's eat free. oh You know, we already have all that.
00:36:45
John S
Got it. Oh, the other guy was going to mention, silly, but... on the J five build and sort of like mentality behind killing
Organizing with Durham Bins
00:36:55
John S
I bought more of those Durham bins. I showed you that picture of the, the bins have the individual trays and they're on a slide sliding pullout system. And, um, that's become a no brainer for like, no no, no, this is going to pay off in the long run for what we do at Saunders and everything.
00:37:12
John S
It's just so nice.
00:37:13
johngrimsmo
It's nice to find something you really like that you can start to standardize and like buy more of.
00:37:19
johngrimsmo
um i was just telling my wife that last night, she ordered a thing from Ikea that's like a small side table, whatever, but with four or five drawers.
00:37:29
johngrimsmo
And you could take out two of the drawers and put a printer in it. And this could be like your mobile printing cart.
00:37:34
johngrimsmo
um And I'm like, that looks really sweet. That looks like the kind of thing we could have four of in this house before too long. You know, it's a craft car, you know, whatever.
00:37:48
johngrimsmo
um had a weird issue on the Kern where the the door to the Aeroa, so when it wants to do a pallet change, the know the machine waits, and then the side the left side door opens up, and then the Aeroa can come in, and there's all these sensors and signals like, yes, the door's open. Yes, the Aeroa can come in. Yes, the Aeroa's out. Now it can close the door.
00:38:08
johngrimsmo
um The closing of the door would start to slam. like like pretty violently. You know, if you're standing in the shop, like, what was that?
00:38:18
johngrimsmo
Even if you know what it is, you're just like, what?
00:38:20
johngrimsmo
Oh, oh, it's that. um So we spent quite a while the past few days trying to figure out what is it? Okay. It's an air operated cylinder. Is there a damper? Is there a bumper that's broken?
00:38:32
johngrimsmo
What is causing this door to fly and not just...
00:38:36
johngrimsmo
like slowly move, because normally it should take, call it two seconds to close fully.
00:38:41
johngrimsmo
um And it's not. And after quite a while of figuring it out, we traced it down to their there's two little regulators or flow control valves.
00:38:52
johngrimsmo
One controls the opening speed and one controls the closing speed. And they have that paint marker on it that like um stops the threads from, well, it shows if the threads have been messed with.
00:39:04
johngrimsmo
Um, so we're like, okay, mess with one of them. Um, we actually unplugged the two hoses. We flipped them. We plugged it back in, uh, knowing that the door would open opposite, but wondering if we can change which one's slow and which one's fast. And it did.
00:39:17
johngrimsmo
we're like, okay, the problem's probably here.
00:39:19
johngrimsmo
So then we started messing with the regulators and we got the open to open really slowly. Okay. So it's not that one, put it back. And then we tightened up the other one and it made no difference at all. So the the more we tightened it, which should have restricted the air more and made it slow, it didn't do anything. So it's clearly something about that regulator is busted or the flow control valve is not working anymore, whether it's the needle seat inside or I don't know whatever.
00:39:45
johngrimsmo
Um, So that's all. We just got to order another one. It's a $40 Festo part.
00:39:50
John S
Can you run it in the meantime?
00:39:52
johngrimsmo
Yep. It just bangs.
00:39:54
John S
Sounds like a TPU printed rubber bumper could help.
00:39:57
johngrimsmo
Not a bad idea.
00:39:58
John S
A little spring in there.
00:39:59
johngrimsmo
Yep. But that might affect the sensor that tells if it's closed or not.
00:40:05
johngrimsmo
Right? Because it it actually hits paint on paint. I was kind of surprised.
00:40:09
John S
Oh yeah, and that is interesting.
00:40:11
John S
You get some weather, trip sorry, or you figure this out.
00:40:15
John S
ah Oh, it's funny you mentioned that because the Xair R chip thing is a 110-pound drum that's air-driven. And when you turn it on, it it sucks the drum in like 16th.
00:40:25
johngrimsmo
Yeah. And it pops.
00:40:28
johngrimsmo
Yeah. The lid comes down and yes.
00:40:29
John S
Oh, my God. Yeah. Gives you an aneurysm.
00:40:32
johngrimsmo
Yeah, we have um this lid top from Lee Valley that's like this plastic thing that you hook a shop vac up to a 55-gallon drum, put this plastic lid on top, and it's like a cyclone.
00:40:42
johngrimsmo
It's like a dust deputy, but for a 55-gallon drum.
00:40:47
johngrimsmo
And that does the same thing. It actually folds itself upside down and does that same loud pop.
00:40:54
johngrimsmo
um But we used that to suck coolant out of the machines before we had the Freddy. And I think even still the guys used it for some reason.
00:41:02
johngrimsmo
as a rough rough clean out.
00:41:06
John S
Other random share. Before we hit record, you were mentioning you changed your computer setup in the in your office. I have sort of inadvertently realized how much I love using remote desktop.
00:41:17
John S
I use Chrome's remote desktop, which is free, but
00:41:18
johngrimsmo
Yeah. Yeah, I use it a lot.
00:41:21
John S
I have my laptop, two work computers, one in the office, one on the floor, and then I have actually two computers at home. um And used to have Fusion on all of them. I still do, but like now I've just gotten in the habit of, I always remote into my main work computer.
00:41:36
John S
It's just like the home base. It probably is the most powerful, but it's not even about that. It's just easier, even though you have cloud software and all that.
00:41:42
johngrimsmo
Right. But, but you got close the fusion on the one you left it open over here.
00:41:47
johngrimsmo
It's it's for me, my, um, the laptop that's in the shop floor is kind of connected to the current it's, you know, it's got the, uh, the VNC server, all this stuff.
00:41:57
johngrimsmo
It's just, it's got everything. Um, so I do quite a bit of that. I do find a lag that's mildly annoying, at least on my, um, um,
00:42:04
John S
Oh, really? What software do you use?
00:42:07
johngrimsmo
ah Chrome remote desktop.
00:42:10
johngrimsmo
So we have pretty fast internet speed at work too, but maybe not as fast at home. um Yeah, it's just like, ah you can tell there's something, something slow you down a little bit.
00:42:20
johngrimsmo
I don't really care unless I'm, you know, if it annoys me, I'll close it. and I'll open it locally where, where if I am at home or whatever, it'd be like this weekend, I don't want to do that. I'm going to do it here.
00:42:31
johngrimsmo
I'm just live, you know, but yeah, i use it quite a lot, tons.
00:42:37
John S
It's free, which although frankly, if it was like, i don't know TeamViewer or Faster, I probably should pay for it at this point.
00:42:37
johngrimsmo
that's for Yeah,
00:42:42
johngrimsmo
yeah exactly. um And sometimes because I have so many Raspberry Pis kicking around, i I'll be like four layers deep. You know, I'm i'm remote desktop into my work PC.
00:42:53
johngrimsmo
And then from there, I'm into a Raspberry Pi. And then from there, I see a second Raspberry Pi. And I'll show my kids that sometimes. And you have like, and and in Windows, you have your Windows bar on the bottom, and you have a second Windows bar on the bottom. And then you have a Linux bar at the top.
00:43:07
johngrimsmo
And my kids are like, Dad, that's not cool. the That's just weird.
00:43:11
John S
it's funny I had a fun memory this morning of I asked the kids to clear the 3D printer at home before they left for school um so I could start another print.
00:43:22
John S
And I was going into a meeting and I knew the print was done. i was like, hey, I know you guys are going to do it, but can you do it right now so I can start this next print? I'm watching the bamboo from this board meeting and I see William's hand on the camera.
00:43:35
John S
So I pop open notepad. I remote into that computer. I pop open notepad. I'm like, Hey William, thanks for doing that. Knowing, not sure if he'd be looking at the computer screen cause it's a little bit off to the side. And he did. So we had this little conversation over windows notepad, um, which is what I used to do as a kid before there were cell phones and you were trying to help somebody you'd remote into their computer and then you'd have a conversation with them over text edit or whatever.
00:43:54
johngrimsmo
eat Yep, yep.
00:43:56
John S
It was just fun memories.
00:43:57
johngrimsmo
That's amazing.
00:44:00
John S
I was on tap for the of the day or week.
00:44:03
johngrimsmo
Today, bunch of the guys left early for various reasons. I think I got the shop to myself now. It's 3 o'clock. um What am I doing?
00:44:14
johngrimsmo
Fixing the looping problem on the Speedio.
00:44:16
johngrimsmo
A couple other little things like that. And then... Yeah, don't know.
00:44:23
John S
You're not going to the Elliott answer this year? I saw it on YouTube.
00:44:25
johngrimsmo
I am actually. I'm going tomorrow.
00:44:26
John S
Oh, good. Have fun.
00:44:27
johngrimsmo
Yep. Yeah. So that's, that's a good point.
00:44:29
johngrimsmo
I'm bringing some of the guys. Steve's going to come with me for the whole day. We're going to go to all four locations. Grayson and Jeff are going pop in and do some stuff as well. um
00:44:38
johngrimsmo
Yeah, that'll be good.
00:44:40
johngrimsmo
And one of the beautiful benefits, if I go to all four locations, I get eight hours of free service on one of my machines.
00:44:46
John S
Yeah, remains like the best deal ever.
00:44:49
johngrimsmo
And some yours, we forget about it and we don't use it. We don't have to use it, whatever.
00:44:52
johngrimsmo
um But we have used it a couple of times and we're like, yeah, they come in and poke at the Mori for eight hours. Make sure it's good. Like, yes, please.
00:45:00
johngrimsmo
yeah Oh, your filter canister has got a crack in it. it You know, here's a, you got to pay for the parts, but like, okay.
00:45:06
John S
Yeah, that's still awesome.
00:45:08
johngrimsmo
Yeah. Thanks for looking. I didn't look, you know?
00:45:13
johngrimsmo
So yeah, we got to make sure to take advantage of that because I don't think we did in the past year.
00:45:17
johngrimsmo
And we have, of the four locations that we're going to, ah almost all of our equipment is from one of those four locations, except for the current.
00:45:25
John S
yeah that's perfect. That's great.
00:45:26
johngrimsmo
So it's great. Yep.
00:45:29
johngrimsmo
You, anything coming up?
00:45:31
John S
Nothing, nothing, honestly, nothing noteworthy.
00:45:33
John S
