Introduction and Episode Setup
00:00:01
John S
Good morning. Welcome to the business of machining episode number 388. My name is John Saunders.
00:00:07
johngrimsmo
And my name is John Grimsmough.
00:00:09
John S
John and I check in each week to see what we're, what's tickling our fancy, what we see and learn and and don't know and and what we can do better. Yeah. How you doing?
00:00:20
johngrimsmo
Uh, interesting. I'll start out.
Late-Night Shop Troubles
00:00:23
johngrimsmo
Um, so last night I came into work, you know, after dinner with the family, I'm like, I'm going to go in for a couple hours. I'm going to work on the field. I'm going to get a few hours to the shop, quiet shop to myself.
00:00:30
John S
Yeah. Yeah.
00:00:32
johngrimsmo
The curtains busy, but I need the speedio and some other stuff. Um, so I get in and there's some weird lights on the curtain and I'm like, Oh man. And then I walk around and it says tool not found. And then I look in the tool rack, like the the library of tools, basically.
00:00:48
johngrimsmo
And there's a tool on the ground.
00:00:50
John S
Oh.
00:00:51
johngrimsmo
it dropped a tool holder and that's never happened before. So I'm trying to figure it out. I literally go get the GoPro and put it in the tool rack and do a fake tool change just to like see if I can see it better with the GoPro or whatever.
00:01:05
johngrimsmo
And in the end, I ended up filming a big long knife making Tuesday, including that and feel stuff.
00:01:11
John S
ah
00:01:12
johngrimsmo
I'm pretty happy with that outcome. um one of the issues there may be two issues with the current tool changer i mean we've been running it hard for four and a half almost five years now yeah and uh the way it works it's like this big wall with like bookshelves of tools kind of thing like each tool just goes one against the background you open the door and you just see every single tool and you can pull anyone it's it's gorgeous and up until last night
00:01:22
John S
That's crazy.
00:01:32
John S
Mm hmm. It's beautiful. I love it.
Tool Changer Troubleshooting
00:01:41
johngrimsmo
I was like, this is the best tool changer that's ever existed, because it's so handy. It's so easy. You can replace tool while the machine's running, which is insanely valuable. um And there's basically two belts that move the gantry side to side and up and down.
00:01:55
John S
Mm hmm.
00:01:56
johngrimsmo
And the side to side has two belts, one on the top, one on the bottom. The bottom one coincidentally happens to get dripped and coolant perpetually. Every tool that comes out of the machine dripping wet drips onto this bottom belt and it broke.
00:02:10
John S
Oh, the belt broke.
00:02:11
johngrimsmo
belt it got the rubber on the outside gets squishy and I can feel it it's like super squishy and actually the fibers or whatever that makes a belt super strong like started to snap and there there became some some flex in this belt at that spot and I could feel along the belt and you push and it's like hard hard hard squish and for like a three inch section it's just uber squishy
00:02:13
John S
Oh.
00:02:24
John S
Mm hmm.
00:02:41
johngrimsmo
And so because the X axis or the left to right axis has an upper belt and a lower belt with a gantry vertically between them, the lower one has some backlash, like like half an inch of backlash or something, and the upper one's accurate.
00:02:54
John S
Yeah, sure Interesting
00:02:58
johngrimsmo
So tools in the upper rack are changing accurately, but tools in the lower rack are either failing or missing to grab entirely. so Yeah, coming late last night, that was my kind of nine to midnight project was trying to understand what the current is doing.
00:03:15
johngrimsmo
um And then I eventually got to the point where I'm like, well, nothing I can do about it tonight. The guys will handle it in the morning and they can start to like take it apart and debug it and figure it out. But I basically determined I'm not running it tonight, so that's okay.
00:03:28
John S
Yeah.
00:03:30
johngrimsmo
I tried to run it a couple more times and dropped a couple more tools and I was
Filming and YouTube Challenges
00:03:32
John S
We're done.
00:03:32
johngrimsmo
like, okay.
00:03:34
John S
We're done.
00:03:34
johngrimsmo
Yeah, like like maybe it'll work.
00:03:36
johngrimsmo
Let's try it. um But it was fun to be able to film that whole process. And I haven't wanted to film in quite a long time, but I kind of jumped into it last night.
00:03:43
John S
Yeah.
00:03:47
johngrimsmo
And it was it was fun to share the journey and the questions and the troubleshooting and the...
00:03:48
John S
yeah
00:03:51
johngrimsmo
I actually filmed a few tools dropping, which is kind of cool.
00:03:54
John S
oh Well, good good for you.
00:03:56
John S
Thank you for, you know, we could we could commiserate a long time over what has become of YouTube. But I think um we did the same thing this week. I filmed a shop update where I was like, Hey, here, I got a list of 10 things I wanted to share and talk about.
00:03:57
johngrimsmo
Yeah.
00:04:07
johngrimsmo
Nice.
00:04:09
John S
And it's simply for the folks that want to learn and enjoy. I love being a consumer of YouTube.
00:04:14
John S
it's There's so much phenomenal content out there, but it is now a commercialized rat race and we're not on that path.
00:04:14
johngrimsmo
Yeah, me too.
00:04:17
johngrimsmo
Yep.
00:04:20
johngrimsmo
Yep.
00:04:22
John S
So it it changes the, you know, we're, we're swimming upstream on that front, but like, great. Like I'd much rather see you show real life with the current than hear some guy yell.
Impact of Niche YouTube Content
00:04:32
John S
some excitement thing about some tool that's being pushed far beyond any realistic, like this is just stupid. Anyway.
00:04:39
johngrimsmo
Yeah, and I find myself really enjoying um very technical, very nerdy, or very personal videos on YouTube.
00:04:39
John S
um Yes.
00:04:46
johngrimsmo
And that's exactly what I do. But when I'm watching other people's content, whether it's, you know, your stuff, but or other industries, some chemistry videos from Val Red or some other ah engineering videos or Veritasium or like, like interesting, nerdy, like enjoyable stuff, or the whole watchmaking scene has a ton of enjoyable videos.
00:04:56
John S
Yeah. Yeah.
00:05:05
John S
Yes.
00:05:06
johngrimsmo
Factory tours or just a guy sitting there, you know, wristwatch revival, kind of restoring an old Rolex for an hour. And I'm just like glued to it.
00:05:13
John S
what Why is that so fascinating?
00:05:17
johngrimsmo
i do It gets like a million views every episode. I'm like, this guy's having so much fun.
Influential YouTube Creators
00:05:23
John S
Well, on that note, and I'm thinking, thinking on top of my head here, some YouTube channels that are, you know, must watches when they come out, uh, breaking taps, um, Adam, Adam, the machinist, uh, silos garages.
00:05:31
johngrimsmo
Yeah.
00:05:34
John S
I don't know if silos posts as much anymore, but he built that diamond turning lathe and I've been going through a lot of his or content.
00:05:37
johngrimsmo
Yep.
00:05:40
John S
Um, Robin Ranzetti, um, who helped me out here.
00:05:41
johngrimsmo
yeah
00:05:44
John S
Who else are you?
00:05:46
johngrimsmo
Um, I don't actually like have the notifications on and like, Oh, somebody posts.
00:05:50
John S
Yeah.
00:05:50
johngrimsmo
I just look at the homepage on YouTube and just want to be enjoyed or entertained for however much time I have.
00:05:53
John S
Yeah.
00:05:57
John S
You to come to the Algo, huh?
00:05:57
johngrimsmo
Um, yeah, I guess so.
00:06:00
John S
Dan Gelbert, God bless that guy, sorry.
00:06:01
johngrimsmo
And yeah.
00:06:03
johngrimsmo
Has he put up a video in years? I don't know.
00:06:05
John S
No, except I realized that he has had put out some stuff more recently than I thought, um which is which is super awesome, but it's still, he's not like a content creator um by any means.
00:06:10
johngrimsmo
Hmm.
00:06:17
johngrimsmo
Right, no, my two favorite videos of his, if anybody hasn't seen them. One is where he talks about his air-bearing lathe that he made from scratch.
00:06:24
John S
Yes.
00:06:24
johngrimsmo
It's like a five, seven year old video. Just super enjoyable. And then the other is his shop tour, where he talks about every machine and that heat treat oven he built, the vacuum service himself, how he has garbage cans in the floor so he can just sweep into the garbage, like all this crazy, like genius stuff.
00:06:37
John S
Yeah, yeah.
00:06:42
John S
Um, it is also so his he he Google's well or he's Google a bull and you can look at his well earned
Machinery Obsolescence Discussion
00:06:50
John S
fortune for lack of a better word comes from the other the optic optics industry or something in that world.
00:06:54
johngrimsmo
Yep, yep.
00:06:56
John S
um But a guy where there's money is no limit. And it's it's almost, and I say this humbly, it's almost a cautionary tale though, because whenever he built that shop, um let's say it was 20 years ago, it was kind of a like no holds bar.
00:07:09
johngrimsmo
All
00:07:11
John S
But he is also, he's clearly the kind of guy who's going to buy equipment that he's going to use.
00:07:15
John S
It's not just a, oh, in the lottery and now I'm going to put 20 cars in my garage.
00:07:15
johngrimsmo
right.
00:07:16
johngrimsmo
Yeah. No.
00:07:19
John S
um That being said, a lot of his stuff looks old.
00:07:23
John S
like And when it's a, oh my gosh, his manual lathe where he built that chuck that has the ability to dial and run out without actually moving the part, like you're actually flexuring the chuck. That's incredible. That doesn't age. But then you see that open so open frame bikini CNC in the corner and you're like, oh, that thing actually probably still makes great parts.
00:07:23
johngrimsmo
Yeah.
00:07:38
John S
So maybe it doesn't even matter.
00:07:39
johngrimsmo
Yeah.
00:07:39
John S
But it is a humble reminder that um And actually, I'm stealing this observation from Adam, the machinist, a long time ago, but it's just like, don't succumb to thinking that the CNC machines or other equipment we bought has perpetual life value, or it can be can be a way to fund your retirement. Because I hate to say it, but my Wilhelmin and your Kern will at some point be be sold.
00:08:05
John S
um you know be They'll either be literally run to the point where maintenance doesn't make sense to keep them in their soul for to somebody else or they'll just like they will have an end end of life.
00:08:15
johngrimsmo
Yep, eventually they will be scrap metal. Which is sad to say, but I remember those words from your voice in my head last night when I'm looking at at this V-belt, or, you know, to his timing belt, and I'm like, I told Leif this morning, I'm like, everything breaks.
00:08:17
John S
yeah if
00:08:25
John S
ah
00:08:29
johngrimsmo
Actually, he always teases me for the current breaking because I tell him every time it happens. I never tell him every time it works great.
00:08:34
John S
Yeah, right.
00:08:35
johngrimsmo
So I'm like, Leif, I told him this morning, Leif, promise not to make fun of me when I tell you this. No. And I'm like, the current broke again last night. He starts cracking up. It always freaks.
00:08:47
John S
Is that a Canada tire belt or is that a Kern FedEx overnight belt?
00:08:50
johngrimsmo
It's a Festo belt. um Actually, I don't know who makes the belt itself.
00:08:52
John S
Oh.
00:08:54
johngrimsmo
It's not branded by itself. Kern sells the entire axis of that gantry, which is a $2,000 part with extruded aluminum and pulleys and stuff. And I'm like, dude, it's it's a hundred dollar belt.
00:09:05
johngrimsmo
Like I just got to find it.
Community Support in Manufacturing
00:09:07
johngrimsmo
So I cut off an inch of that belt.
00:09:07
John S
Yeah.
00:09:10
johngrimsmo
And then it's an open belt, not a closed belt, so it's pinched on the two sides.
00:09:13
John S
Oh, even easier.
00:09:15
johngrimsmo
So you just need to find a source that has, you know, 100 feet of this belt in a spool and cut off however many feet, 12 feet that I need.
00:09:22
John S
Go.
00:09:24
johngrimsmo
um Coincidentally, since we are in Manufacturing Central, I was able to drive three buildings over at this new building they just built. And it's it's like a sort of conglomerate shop that has multiple locations. And I was like, I wonder if they have this belt. I go to their website. I know their location in downtown Hamilton, like half an hour away, would absolutely have this belt in stock. And I'm like, I wonder if this two buildings over has it in stock. So I walked there and I'm like, yeah, this is a really nice new building.
00:09:53
johngrimsmo
I drive by it every day. We watched them build it. I didn't know what was going to be in there. I kept joking with the guys. I was like, that's our future headquarters. um So I walked inside this huge and pretty nice, more of a warehouse than anything else.
00:10:00
John S
Yeah.
00:10:06
John S
No.
00:10:06
johngrimsmo
Tiny little bridge port in the corner just to do bearing replacements and stuff.
00:10:10
johngrimsmo
Um, but a lot of inventory and I was hopeful. And so I brought this little one inch length of belt and I was like, do you guys sell like Gates timing belts? And he goes, not here, but I can get them from Toronto like tomorrow or something.
00:10:22
johngrimsmo
So he took that in the info and he's going to email me back very shortly. Um, just super handy.
00:10:27
John S
um i'm I'm shadowing Freud in Lee happy because I was going to be pretty upset if you were like, yeah, they had it and I just walked out with it like good.
00:10:34
johngrimsmo
Yeah. Yeah.
00:10:34
John S
No good for you. That's a that's great.
00:10:36
johngrimsmo
and And I could jump around, there's some other locations. And he even he mentioned some of those other locations. He's like, BDI might have it. And I was like, yeah, I thought about that. But he's like, they they might not. like But let me take the info.
00:10:46
John S
Yeah.
00:10:48
johngrimsmo
I will dig in this and you get back to work and I'll i'll send you an email as soon as I can with, I'll find something for you. So it's good.
00:10:56
John S
Yeah, right. So current idling right now.
00:10:58
johngrimsmo
No email yet, but it's only been half an hour.
00:11:03
johngrimsmo
So that's great.
00:11:10
johngrimsmo
Still there? I can't hear anything. You sound awfully quiet.
00:11:21
johngrimsmo
Check, check. Check, check. Hmm.
00:11:46
johngrimsmo
You're back.
00:11:47
John S
Cool, what happened?
00:11:49
johngrimsmo
I don't know.
00:11:50
John S
Oh, okay.
00:11:51
johngrimsmo
Weird.
00:11:51
John S
did Did you see me still?
00:11:53
John S
Or sorry, did you?
00:11:53
johngrimsmo
I saw your, your, your screen was frozen and I couldn't hear anything.
00:11:56
johngrimsmo
Could you hear me?
00:11:57
John S
It just looks like you dropped, but I don't mean to make it sound like I'm the one that's so correct and you're wrong, but I just don't even know why I would.
00:12:04
johngrimsmo
Maybe it's a Zencaster glitch of the internet kind of thing. I don't know. I signed it.
00:12:07
John S
Yeah, weird, okay.
00:12:08
johngrimsmo
It wasn't that bad.
00:12:09
John S
Okay, so just so we know, um oops, where was that?
00:12:12
johngrimsmo
Yeah, I got it. It was 11 minutes, something.
00:12:13
John S
Okay, you got it, great.
00:12:15
johngrimsmo
I might just leave it in, who knows?
00:12:17
John S
Yeah, right. We'll see, make sure it's hanging.
00:12:20
johngrimsmo
Yeah.
00:12:23
John S
I lost my notes. Go ahead. Okay, so current idle right now then.
00:12:23
johngrimsmo
All right, sounds good.
00:12:27
johngrimsmo
Kern is just sitting there. The guys are taking out that gantry assembly, because it'll be way easier to replace the belts when it's out.
00:12:33
John S
Yeah, right.
00:12:33
johngrimsmo
There's a little cult Kern, they talked to them, they said, yeah, usually we just replace the whole thing, we send a service guy. I'm like, ah this is is way too easy.
00:12:39
John S
Yeah, no.
00:12:43
John S
You have to read home or calibrate, I guess.
00:12:45
johngrimsmo
the Because it's two axes that are synced with a mechanical coupling, um the top one's still good.
00:12:50
John S
ah
00:12:53
John S
got it Got it.
00:12:53
johngrimsmo
And you can just adjust the bottom one.
00:12:54
johngrimsmo
As long as the vertical gantry is actually vertical, it should be fine.
00:12:57
John S
Yeah. Got it.
00:12:59
johngrimsmo
So um we'll figure it out.
00:12:59
John S
Sweet.
00:13:02
John S
You've replaced glass in a machine before?
00:13:05
johngrimsmo
And the Nakamura, yeah.
00:13:06
John S
And and did you buy the Knack glass or did you just go to the glass shop?
00:13:08
johngrimsmo
Yeah, yeah, we did. Yeah, it was $1,400, I think.
00:13:09
John S
Ah, okay.
00:13:12
John S
Okay.
00:13:13
John S
We were, oh really?
00:13:13
johngrimsmo
But it's like an inch thick.
00:13:15
johngrimsmo
it's It's literally bulletproof glass. Yeah.
00:13:17
John S
Okay. Yeah, I'm late, I guess.
00:13:19
johngrimsmo
Yeah.
00:13:20
John S
Okay.
00:13:20
johngrimsmo
Especially Japanese Leah.
00:13:21
John S
Our Geno Store's glass could use it. And I was sitting in front of it today because for the first time in years, we just all of a sudden were like, what what's going on? We're running a custom plate that does have a smaller hole size, which you know we just drill.
00:13:36
John S
Everything we drill is like whatever, 11.4, I can't remember, but larger diameter. drill and this is a 8.1 millimeter or 8.2 millimeter drill and um the Sandvik was out of stock so the guys bought some YG1s and I'm more just sharing that I am looking for help at this point but they had three or four drills, I think four, because one, or more, maybe five, because one or two kind of blew up and they had adjusted speeds and and they were getting like 10 to 20 to 30 holes and then the drill was catastrophically shattering off.
00:14:13
John S
um And eight millimeters of 3.32 inches or something.
00:14:14
johngrimsmo
This is like a half inch or a bit, almost like not small. Oh, eight. You said 11. Okay.
00:14:21
John S
And, but it's a material we run have for every day, half per years. um And speeds and feeds are shouldn't be in a shoe like we were we were.
00:14:32
John S
So then I hopped in and we we blew up and the next three drills together.
00:14:37
John S
200 to 350 service feet, six to six thou to one to 10 thou per feed per rev. Yeah, it's still a totally normal
00:14:37
johngrimsmo
In steel.
Drill Performance Issues
00:14:45
John S
recipe.
00:14:46
John S
And it was,
00:14:46
johngrimsmo
You check grooving cut.
00:14:49
John S
It was totally, ah the drill cut quality and load was unchanged for let's say it did 30 holes for the first 29 holes in the 30 hole, boom, immediate shatter.
00:15:01
johngrimsmo
yeah
00:15:01
John S
um And so we switched to a different holder, we we checked run out, and we also switched to a different holder. We started, um the top of this material is face already, the bottom is not, and mill scale can be really hard on drills.
00:15:17
John S
Not normally this quickly, catastrophically, but nevertheless it can.
00:15:21
John S
So we even, bingo, yeah.
00:15:21
johngrimsmo
On the poke through you mean on the side too.
00:15:23
johngrimsmo
Yeah.
00:15:24
John S
So we even tried drilling through leaving 80 thou on the floor, thinking I can come through with a beater drill or something else later and again, deal with that. um And no, they're all gone. They're all blew up. And like the last thing I'm willing to think about is is it could it be a bad batch of carbide or a bad batch of drills? Because it's just always something.
00:15:45
John S
you know you're always the culprit like just generally speaking is my kind attitude but what really got me was um we found a we have a carbide drill drawer which frankly i should really just throw all that recycle all that because without saying this story it's never been useful.
00:15:48
johngrimsmo
Yeah.
00:16:01
John S
ah And sure enough, we had the Sandvik drill that we didn't, that was out of stock, it wasn't out of stock, it was like a five day lead time, out of because it's got to come out of Europe, and we're in the middle of this, it's not a hot job, but I don't want to i want to finish that plate while it's on the machine, I don't want to wait six days.
00:16:16
johngrimsmo
Sure.
00:16:16
John S
And so we found this drill, and it had one flute, two flute drill, one flute was basically great, the other flute had some pretty major chowder on the edge, but you know, it wasn't, I would have no problem trying it, especially in this situation,
00:16:32
John S
drilled the rest of the holes in the plate, like two or 300 holes, no problem, an unchanged condition, load meter stayed exactly the same.
00:16:37
johngrimsmo
i
00:16:39
John S
And so I'm kind of like, part of me thought about calling the YG-1 contact to be like, hey, what's up? And then I'm like, I don't even care. Like it just, but what, what?
00:16:47
johngrimsmo
Yeah.
00:16:49
John S
It's weird.
00:16:50
johngrimsmo
Yeah. I mean, you, you found the magic drill bit that just works perfectly for you, but yeah.
00:16:54
John S
Yeah, but it's not 30 Rockwell 4140, it's not. It's not that hard to do, you know?
00:17:01
johngrimsmo
yeah
00:17:02
John S
So I thought that was interesting.
00:17:07
John S
But yeah, we should replace the door the glass on it. That'd be nice. Oh, I should get a cooler, I guess, to see.
00:17:10
johngrimsmo
Is it, is it just frosted from chips hitting it or yeah.
00:17:13
John S
Yeah, there you go.
00:17:14
johngrimsmo
Okay.
00:17:14
John S
Yeah, over the years.
00:17:17
johngrimsmo
Yeah, the NAC one broke because a seven millimeter drill, long drill broke.
00:17:20
John S
Oh, that's right.
00:17:22
johngrimsmo
ah I can't remember why. I think the guys kind of came up with a reason. But, and then a shard of carbide must have hit the window.
00:17:30
John S
Just perfectly, huh?
00:17:31
johngrimsmo
Yep. And it just totally puts like a windshield in a car.
00:17:32
John S
Yeah, yeah.
00:17:34
johngrimsmo
Million, million little cracks.
00:17:34
John S
That's crazy. But good sense.
00:17:38
johngrimsmo
What do you mean?
00:17:39
John S
that It's been good sense.
00:17:41
John S
Like, no, she's there. Yeah.
00:17:41
johngrimsmo
Oh yeah, it's been, it's been great.
00:17:42
johngrimsmo
Yep.
00:17:42
John S
Yeah.
00:17:44
johngrimsmo
Yep. And then similar with um kind of speeds and feeds and on our Swiss lathe, the we cut a lot of 17.4 pH to stainless steel. It's about 45 Rockwell. We cut it with a V turning insert, 8. radius, a very pointy V small tool. And we've been doing this since forever, like seven years we've had the machine, whatever.
00:18:06
johngrimsmo
um And we have a couple different holders for this tool. Some of them are the quick change indexable head ones, where the head kind of quick changes makes it so much easier to replace the tool.
00:18:13
John S
Okay
00:18:17
johngrimsmo
And some of them are solid. but And our machinist, Jeff, there has been having a bunch of chatter issues with some of the parts. So he's you know trying to reprogram it for a roughing pass. And I'm like, it's a Swiss.
00:18:28
johngrimsmo
You don't need a roughing pass. like Yeah, it can help. But you just want it done. That's what I've been doing forever.
00:18:33
John S
Yeah.
00:18:34
johngrimsmo
And some of the inserts work great. Some of the holders work great. And other combinations just always, always lead to chatter.
00:18:42
John S
Really?
00:18:43
johngrimsmo
Yeah. So some of those, some of those quick change holders are less rigid, Sandvik being one of them than other ones.
00:18:43
John S
You think it's. the Interesting.
00:18:51
johngrimsmo
And I, personal preference, I don't like the Sandvik quick change turning tool holder, um at least for us.
00:18:58
John S
Oh yeah, I mean. No, totally. ah You learn what you learned.
00:19:01
John S
and what what What works works.
00:19:02
johngrimsmo
yeah example
00:19:05
John S
Yeah.
00:19:07
johngrimsmo
So yeah, I think his solution was to go back to the rigid stick tool holder, which is annoying to change inserts because you've got the coolant lines and you've got to reset it and everything, but always gets good results.
00:19:18
John S
that That's a tough trade-off.
00:19:19
johngrimsmo
Right.
00:19:20
John S
that would I would file that in my, ooh, that's a new item on my days off in the shop list, which we when we film in that shop update video, which hopefully will be out by the time this podcast airs, but today we're recording this two days prior and I haven't, I'm just about done editing it, but I kind of talk about the do its fail at the end about like, okay.
00:19:37
johngrimsmo
Yeah.
00:19:39
John S
like i can I can tell you the excuses, but it's also just like, here's where we're at. um And things like this morning, like Caleb and I spent a couple of hours this morning together. And that was good. You learned something, wasn't planned. um ah So we...
00:19:53
John S
Talk about a broken record, I told you last week that like all the VF2 stuff was basically done and then that wasn't totally true because I had run one set of the Shimpworks valve covers on it, but there were, but we make four or five other SKUs of those and I had not run those yet, which, you know, that's the first time you're gonna run through on a new machine.
Valve Cover Machining Challenges
00:20:13
John S
You're gonna sit there and so option stop it through the first program. But it's also the same tools, mostly the same fixture and it's not particularly big deal. Well, I was wrong. um It was.
00:20:23
John S
um it Not only was more of a big deal, but we had one of our overseas distributors be like, yeah, we're ready for a lot more. And I was just like, oh crud, which I like having fires lit for sure.
00:20:37
John S
But it's just all the more like perpetual excuses of like, what's, what's distracting you from actually taking this off your plate.
00:20:44
johngrimsmo
Yeah.
00:20:45
John S
And we have a we have a um tiny vice that we basically moved over from the horizontal and it worked fine for years. And it's now allowing the part to lift up about five thou, which i would but you could actually make that work, which sounds terrible, but it could be okay.
00:21:04
John S
But I don't, like I'm unwilling to accept that. Like why is it happening?
00:21:08
John S
How do I stop that? And so I'm working on that right now.
00:21:08
johngrimsmo
three
00:21:13
johngrimsmo
Yeah. And it didn't do it before or you didn't notice it before.
00:21:18
John S
I am comfortable saying it didn't do it before because if it does do it, the way the parts programmed, you'll see um it's happening when a roughing tool causes the part to lift and and you see it then on the finishing passes. and We would we we would weve caught it immediately when it happened here. Now look, it's a new machine. and so There could be other reasons why it's happening, but I'm just kind of, like I wouldn't have expected that, but there they're, they're tricky.
00:21:43
John S
Your parts to opt to hold because we're, um, the, it's a valve cover. So you're holding against on the outsides of a ah tube effectively. So you can crush it in. If you want, if you can't just clamp harder.
00:21:53
johngrimsmo
Right. Yeah, yeah. Tricky.
00:21:56
John S
Yeah.
00:22:00
johngrimsmo
I remember before I got into CNC machining, I was super into cars, old Volvos. And that's what got me into machining because I would watch guys make valve covers or pulleys or blow off valves for these older cars.
00:22:12
John S
Yeah, very cool.
00:22:15
johngrimsmo
And that's what taught me what a CNC machine was, was the learning, you know, seeing pictures of people who are making that kind of stuff. I'm like, well, how are those made? And then I saw one picture of a guy who had two small VMCs in his basement garage or something.
00:22:30
johngrimsmo
And that lit the fire as like, this is possible.
00:22:32
John S
Yes.
00:22:34
johngrimsmo
This is really cool. And they were, I don't remember what brand they were. Some, some foreign, smaller brand. Um, I can't remember, but yeah, it's, it was like one day, you know, one day.
00:22:46
John S
Yeah. No, John, right?
00:22:47
johngrimsmo
And this was 15, 20 years ago, like way before anything. It's 2005, six.
00:22:53
John S
Like. Yeah, I would have said for me like 2007 or eight, that guy, and I'm pretty sure his his precision machinist handle was a helicopter John's and he put an old Haas tool room mill that was like there when they had, they were like dark slate gray.
00:23:03
johngrimsmo
For him?
00:23:08
johngrimsmo
Yeah.
00:23:08
John S
um And again, I'm thinking that this guy is Bill Gates.
00:23:11
John S
Like this guy has bought a Haas machine. He personally owns a Haas and he has it. He's able to use it. Like I am just like, this is insane.
00:23:12
johngrimsmo
Yep.
00:23:20
johngrimsmo
Yep. And the the scope creep is such a real thing that, you know, in your position now, in my position now, we're like, yeah, but like, no, like, we should be proud.
00:23:22
John S
Yeah.
00:23:26
John S
hu Yeah. Yeah. How's your um totally randomly popped into my head? What's going on with your router and laser and phone? Remember, we were talking about that so much six months ago or more.
00:23:44
johngrimsmo
Grayson is handling it 100%.
00:23:47
John S
Great.
00:23:47
johngrimsmo
Actually, a weird thing happened. this Perfect opportunity, I forgot. I'll tell you about that. But basically, the router is routing foam and lasering foam five days a week.
00:23:57
John S
Okay. Works.
00:23:58
johngrimsmo
Just, it works. It just works.
00:23:59
John S
That's awesome. Good.
00:24:01
johngrimsmo
Um, which is great. Like I don't even think about it or worry about it. Uh, I think, I think supply from the shipping department who needs the phone and grace and making the phone is a little hand to mouth sometimes like, you know, Oh, we got a phone quick.
00:24:05
John S
Okay.
00:24:13
John S
Okay.
00:24:15
johngrimsmo
Um, I know they're working on it and they're always trying to keep the buffer needed, but, um, I just, as the owner, I kind of hear chatter and I don't have to deal with it, you know, which is great.
00:24:23
John S
Yeah, sure. Yeah.
00:24:26
johngrimsmo
However, so yesterday Grayson came to me he said, um, the router's being weird and I don't know what's going on. And then I was like, well, i'll dig into it and let me know what you find comes back a little later. And he's like, the x axis is move trying to move to negative 82 inches. And it's a 24 inch travel.
00:24:48
johngrimsmo
Okay, so he found the line, and it it has a graphical interface on the Maso controller, so it it shows the toolpath, basically. um And you can see this one line no way off to the side, and all these other little engraving texts that are where they're supposed to be. And he traced it down to that line, line 36,000, whatever it is, and and then he compared it, and it's it's weird. It reads G negative zero, zero, zero, eight, two, and then the feed rate.
00:25:19
johngrimsmo
And what happens is it disappeared the decimal and a zero and a five.
00:25:23
John S
No.
00:25:25
johngrimsmo
They just got deleted for some reason in in the middle of the program.
00:25:29
John S
Wait, have you have you seen this episode from somebody like Veritasium?
00:25:34
johngrimsmo
I think it's smarter every day.
00:25:35
John S
It's more to be where it's like chips have, silicone has defects and it can actually drop decimal places. It was like, a there was a came up in like a gambling machine, just ringing bells in the video.
00:25:45
johngrimsmo
I wasn't the Super Mario Brothers, there was this ah glitch level I think he talked about.
00:25:49
John S
Maybe, yeah.
00:25:50
johngrimsmo
um and And I think the title of the video is, this is why computers don't work in space, right?
00:25:55
John S
Yes, I think that was it, okay.
00:25:57
johngrimsmo
And because space particles, quantum, yada, yada, will change a bit from a one to a zero, unpredictably, right?
00:26:03
John S
Yes, that's it that's exactly what it is, yes.
00:26:06
johngrimsmo
And he said, you know, there's a theory going that this super secret level of Super Mario, somebody who was live streaming ah original super mario and and he glitched through a wall or something and i think that's why because they check the code afterwards and the code is wrong anyway yeah so i talked to grayson about that and he'd also seen that video and i was like maybe or more likely okay where is this data stored on the maso controller this is more of a diy controller it's a phanic it's a high nine it's like it's it's a thousand dollar control that you can put on a router
00:26:20
John S
Yes.
00:26:39
johngrimsmo
all programming files are stored on the USB stick and run from the USB stick.
00:26:44
John S
OK.
00:26:45
johngrimsmo
And I'm like, what is the likelihood that this 30 cent USB stick is just failing?
00:26:51
John S
Right.
00:26:52
johngrimsmo
You know? And so we said, okay, go back to your computer, check the original source code, make sure it's good, transfer it over again, see what happens. And he goes, that problem's fixed, but another problem happened. It moved another bit.
00:27:08
johngrimsmo
like Maybe, maybe it's time to pony up and buy a $20 USB stick. That's like good and not.
00:27:14
John S
via like, what are they, uh, like ECC, like radiation proof memory stick.
00:27:19
johngrimsmo
Yeah, I don't even know. I told him to look into it, but, um, so that was a couple.
00:27:21
John S
Right. This feels like a good line at Linus tech tips.
00:27:25
John S
Like tell, show me the way.
00:27:25
johngrimsmo
Yeah, exactly.
00:27:27
johngrimsmo
That was a couple of days ago. Um, I don't know where he's at, but he hasn't complained. So I assume making progress. And, but yeah, kind of a funny story. And I was telling a programmer friend of mine and I was like, I got one for you.
00:27:39
johngrimsmo
And he's like, usually a USB stick would just fail, like corrupt memory is bad. It won't load. It won't boot. It won't read, whatever. And not just drop bits, you know, characters, but I don't know.
00:27:48
John S
Yes.
00:27:52
John S
Yeah.
00:27:55
John S
That video for the folks listening, which I highly recommend is called the universe is hostile to computers.
00:28:03
johngrimsmo
I'll put in the show notes here.
00:28:04
John S
And it is very tossing them in. It's a great
00:28:07
johngrimsmo
Is it has some, okay.
00:28:08
John S
Um, just like one of those, like just checks, all the boxes. Um, although have you heard the joke that like the average male thinks about the Roman empire once a week?
00:28:17
johngrimsmo
The Roman Empire.
00:28:18
John S
Okay. Yeah. So my wife, I don't, but like, I probably think about world war two twice a week, you know, like, um, and I'm not even like a crazy history buff, but, uh, yeah, it's kind of like, they clearly upward, different than whatever.
00:28:19
johngrimsmo
I do not.
00:28:24
johngrimsmo
Okay. That's your version of it. Yeah.
00:28:35
johngrimsmo
Now, if it's space or something, that that's my kind of Roman empire, I guess.
00:28:35
John S
Uh,
00:28:38
John S
Yeah, yeah.
00:28:40
johngrimsmo
But, uh.
00:28:40
John S
No, I was talking to, oh, Justin, the CTO at Toolpath about failure mode and infusion cam. And it's just like, I, like, I don't mind if it fails, but when it fails, I want it to fail.
00:28:53
John S
Uh, he had a better, much better term for it, but like tell, no, like tell me it's failed.
00:28:55
johngrimsmo
Safe.
00:28:58
John S
Don't, um, don't. let allow the possibility that it keeps running because then I don't ever know. Like in this case, which I don't know how you, how do you do parity checks or or data checks on that stuff, but.
00:29:07
johngrimsmo
Yeah.
00:29:09
johngrimsmo
Yep. And, and if this was a Z issue, it would be a bad day.
00:29:13
John S
Oof, yeah. Right, right.
00:29:16
johngrimsmo
I mean, it's just a router and it's made of superglue basically, but it's, uh, for sure.
00:29:16
John S
Yeah, that's fair.
00:29:21
John S
No, but that stuff's real because it's more, look, it's money, it's time away, it's, um yeah.
00:29:25
johngrimsmo
Mm-hmm.
00:29:30
John S
Okay, off topic-ish, but. um My wife is um like putting a new decor in her little home office and She put it on wallpaper and she wanted a new piece of artwork. We're talking about it. And I so think I've mentioned before, really just love the artist Donald Judd. And I've made a number of his replicas myself over the years. And I had the new one that I'd always thought about wanting to make or what I hadn't yet made. And it's this kind of bulbous brass shaped thing, a sculpture. And so I thought, you know what, I think I can do this. And as much as I wanted to make it out of,
00:30:05
John S
Aluminum or machined or even sheet metaled and I thought about send cut sand or other versions I was like no I actually think I could pull this off with 3d printing If not as the final product, maybe just a proof of concept and it's pretty long It's about 30 inches long and 8 inches high and 10 inches deep.
3D Printed Sculpture Process
00:30:22
John S
So it's a large piece um And long story short, printed it in four sections on the bamboo.
00:30:28
John S
Each of the four prints was 23 hours, um but printed it with guide pin holes and then printed some drift pins that pressed in. It aligned it all up and then um welded the section or glued the sections together with those drift pins to align it and then spent probably three days, like just nights, weekends for fun, but probably a good three days or four days trying to bondo it.
00:30:50
John S
And I suck at bondo, like it's so,
00:30:52
johngrimsmo
yeah
00:30:53
John S
It's so rewarding because you know you get sections good, but you don't want to have sections good. You want the whole thing perfect. And I suck at it. I actually almost thought about like stripping it down and just taking it to a body shot.
00:31:05
John S
But then I kind of gave it one last hurrah and got it to a point where everybody else will probably think it's fine. I'm i'm still not.
00:31:13
johngrimsmo
Yeah, it's the artist curse.
00:31:13
John S
you know yes yeah i guess um but um i don't know why i brought that up oh yeah so the other thing that stunk was that i watched some youtube videos and there were some good examples of guys doing just this basically some version of a body filler or similar along with sanding and then primer and then they're able to get shiny glossy reflective paint That's where I couldn't, I ended up settling for a matte gold. It still looks awesome, but it wasn't what I wanted. And that bothered me. Sorry, long range question. Have you done anything like this?
00:31:45
johngrimsmo
um I bought cans of Bondo in my teenage years to make rock climbing holds.
00:31:54
John S
Really?
00:31:55
johngrimsmo
Yeah, because you mix sand and Bondo and you can apparently make the holds for indoor rock climbing.
00:31:57
John S
Oh.
00:32:00
johngrimsmo
And we had a barn shed in our home house and I was like, I just want to put rock climbing holds all over that thing. It'd be sweet. Never did. But that's my only experience with Bondo.
00:32:08
John S
Tell me you don't still have the, okay, fair enough.
00:32:10
johngrimsmo
No, no.
00:32:12
John S
Got it. Well, I want to get that. It's so actually something i I genuinely enjoyed it. Like I haven't had a project like that on the side that I've really bought.
00:32:19
johngrimsmo
It's fun, right?
00:32:20
John S
Yeah. And so I think I'm going to print some small pieces that are only one flat surface that went on to worse worry about bonding across joints and in curves. and practice a little more because I think with the right sanding primer and then there are really good spray paints that can look great.
00:32:38
johngrimsmo
yeah
00:32:38
John S
I want that ah want it to look like that can candy well dot candy red, but like that shine, like a carpet, you know, like glossy reflective, just cherry.
00:32:43
johngrimsmo
ye
00:32:45
johngrimsmo
would you Would you remake that artwork if you get it nailed?
00:32:50
John S
Too soon, too soon.
00:32:51
John S
I just hung it up this morning.
00:32:52
johngrimsmo
I'm, I guess I'm saying I'm trying to temper your free time.
00:32:57
johngrimsmo
If is, is getting really good at this skill, other than the fun of it, I totally understand. I'm going to do anything for you.
00:33:02
John S
Yeah. Uh, there's a pride of craftsmanship.
00:33:06
John S
You're right. Look, I, I made the call that you're alluding to, which is this morning. I was like, I gotta call this. It's been a good run.
00:33:06
johngrimsmo
Absolutely.
00:33:11
John S
I like, this was kind of cutting into my Johnny five time of like nights and weekends.
00:33:12
johngrimsmo
Yeah.
00:33:14
johngrimsmo
Yeah. Yeah. Right.
00:33:15
John S
So I'm, I'm happy with that, but, um, I want to do better.
00:33:21
John S
So, um, but I also don't want to be the, uh, definition of a guy who just keeps doing the same thing, expecting different results. Like I got to figure out what, um, cause some of it did look really good.
00:33:21
johngrimsmo
Yeah.
00:33:29
johngrimsmo
Yep.
00:33:30
John S
And I'm, look, I'm, I'm rattle canning with different, uh, bear rasolium and Krylon finished paints to experiment with the finishes there. Maybe I just need to go to airbrush because most of the guys.
00:33:43
John S
on YouTube or using airbrush paint, which isn't even that expensive to buy one. I also, to your point, I would not have a ego problem of just finding a body shop to finish it because that's what they do.
00:33:52
johngrimsmo
Sure.
00:33:54
John S
um yeah
00:33:56
johngrimsmo
It's like ah one of my neighbors older guy, he built his house 30 years ago or 30 or 40 years ago, um, when he was 23 with his own two hands, like he helped build it kind of thing.
00:34:07
johngrimsmo
And now he's redoing some of the work, like putting new handling up on the sides.
00:34:08
John S
Yeah. Mm hmm.
00:34:12
johngrimsmo
He's putting a deck on, like he's redoing his original work and he's a retired accountant now. So he's not a contractor by any means, but he's, he's getting really, really, really good at doing a project once.
00:34:20
John S
Yeah, yeah, yeah.
00:34:25
johngrimsmo
and learning all the skills and never needing it again.
00:34:27
John S
Right, that's funny.
00:34:28
johngrimsmo
Now, this is house. This is passion project. It's wonderful. But we do joke about this and we're like, yeah, nobody's better than than him, but he's never going to use it because it's not.
00:34:36
John S
every There's something about, I don't know, yeah, here's a there's a picture of it right there.
00:34:42
johngrimsmo
Oh, that does look really cool. It looks good.
00:34:44
John S
But the the Judd versions, yeah, the Judd versions though are,
00:34:46
johngrimsmo
It's shiny. Yeah.
00:34:50
John S
like C3PO, like pure reflective brass or, I believe it's brass not copper.
00:34:54
johngrimsmo
Yeah.
00:34:57
John S
And look, when you get up close to them, i've seen I've seen a number of them at galleries and auction places. They're not perfect either, that's the funny thing, but um I want it to be better.
00:35:03
johngrimsmo
Right. Yeah. Yeah.
00:35:06
John S
So, yeah.
00:35:07
johngrimsmo
Very cool.
00:35:08
John S
yeah
00:35:12
John S
What else is going on?
00:35:14
johngrimsmo
Let's see here. Did I tell you about the flocking setup for our tumblr?
00:35:22
John S
walking.
00:35:24
johngrimsmo
Apparently not.
00:35:25
John S
It's a family friendly podcast, John.
00:35:27
johngrimsmo
Yeah, exactly.
Improving Tumbling Operations
00:35:28
johngrimsmo
No, if Flock is a chemical or I think it's a clay-based thing where basically it you put it into water and it attracts all of the contaminants and dirt and everything and makes it settle into the bottom leaving basically pure water on the top like people use this for drinking water who's the guy Mark Rober made a video where I'm gonna drink mud and he mixes this water into it and yeah and clean you know some mud settles and clean water flows to the top and
00:35:42
John S
Okay. No kidding.
00:35:52
John S
Oh, yeah, yeah.
00:36:00
johngrimsmo
So we, this is used in the pool industry somewhat. um And what happens in our tumbler is all the ceramic stones break down and all the titanium and stainless steel gets eaten away by the stones and you're left with all the silt and dust and contaminants. And that keeps floating around the water, the slight lubricant in this water. And all that silt gets into the screw holes, it gets into the corners and features and becomes really hard to wash out of the parts.
00:36:29
johngrimsmo
And it also slows down the action of the tumbling like it's it's not ideal. So what some companies do is they flock their water they add this powder um to the water and it settles all the sediment out and then you keep using the clean water. um One of our local friends modus who makes firefighter equipment.
00:36:48
John S
yeah
00:36:48
John S
yeah
00:36:48
johngrimsmo
and and built a sweet tumbling line, built his own flocking setup with a big agricultural, you know, plastic cone shaped water vessel, and automatically puts the flock in the top and and settles it and sips it through some paper and filter bags and things like that and dumps it back.
00:37:06
johngrimsmo
And I saw his setup a couple years ago. And because he's kind of pulling back his manufacturing side, he's like, hey, um it's for sale.
00:37:10
John S
Yeah, yeah. yeah
00:37:14
johngrimsmo
I was like, What's the number here? And he's like, what's this? And I'm like, that's, yeah, we should really get this. So Eric and I went to go see it. And we're like, it's a little janky because it's somebody's DIY project.
00:37:24
johngrimsmo
It's like, they only needed to make one and, you know, learned a lot of lessons, but never made it.
00:37:30
John S
Yeah, yeah.
00:37:30
johngrimsmo
Um, well, we're like, you know, we can take his lessons and learn from it and improve these couple of things. And I think this would be hugely beneficial for us. And we've had this 50 pound bag of flock that we've been kind of afraid to use for a while because of it's so fine that it's a respiratory hazard.
00:37:47
johngrimsmo
So it's one of those big like, you know, you're going to die stickers on the front.
00:37:47
John S
Oh, interesting.
00:37:50
John S
OK.
00:37:51
johngrimsmo
um So the way we've come up with, it we did buy Paul's flocking setup and I figured out McMaster has a bronze venturi that you can that that will flow water through it and suck up any powder or liquid or whatever similar to your 3d printed whole cleaner upper venturi thingy but like proper industrials i bought one of those and now we're going to be able to do one yeah exactly exactly um which i want to know how yours is working but but give me a sec um
00:38:14
John S
Oh, yeah. Yeah. Oh, oh, and eat just cut me some slack there, sir. You like like yours except ours is industrial and commercial. Sorry.
00:38:31
johngrimsmo
I bought this because I don't want to mess around with this, you know, dangerous to breathe flat powder that attracts water and sound like you don't want that in your lungs.
00:38:36
John S
Yeah, we're in.
00:38:41
johngrimsmo
So I bought this proper Venturi to be able to with water flow, suck up the powder as needed and flock the system's water and settle the garbage to the bottom. And the guys are kind of mid install of that right now, which is exciting.
00:38:54
johngrimsmo
It's cool.
00:38:55
John S
I don't know that I, I'm going to look up after you hang up flocking. Cause I don't know that I totally understand. Okay. So flocking the, the, the powder mixes with the water, grabs the dirty stuff, settles it to the bottom.
00:39:07
John S
But then do you skim it somehow skimming off the bottom, which are sucking off the bottom.
00:39:10
johngrimsmo
No, it, if there's this siphon but ah an opening a big ball valve for its ball valve at the bottom that lets you open that and get all that you see the dirt level, so it flows all the dirt down this funnel.
00:39:24
John S
Ah, okay.
00:39:25
johngrimsmo
And then you turn it off and you get clean water.
00:39:25
John S
You drain down, the drain at the bottom.
00:39:27
John S
Sure. Sure.
00:39:27
johngrimsmo
Yeah, exactly.
00:39:28
John S
Okay. It's like just.
00:39:28
johngrimsmo
And there's a different inverter valve that, that turns all the dirty water through a large filter bag, um, which keeps it.
00:39:33
John S
Yeah.
00:39:35
johngrimsmo
And then the cleanish water filters through the filter bag and pumps back into the system.
00:39:39
John S
Okay. That makes sense.
00:39:40
johngrimsmo
So it's, it's a, it's not an automatic solution, but it's a very easy to maintain manual solution. And, uh, once we have it up and running, we'll do a video and explain it cause it's, it's pretty neat.
00:39:49
John S
Yeah, I'd like to see it.
00:39:51
johngrimsmo
Yeah.
00:39:51
John S
Interesting. And this helps, though, with your tumbling water fluid quality.
00:39:55
johngrimsmo
Yeah, and and water consumption, because I think the guys are replacing the entire water tank every two weeks, because it just is hard to maintain.
00:40:01
John S
Got it.
00:40:02
johngrimsmo
maintain And we have a paper filter in the system, which captures a lot of it. It doesn't capture the silts and the finest stuff. um This flock, as Paul showed me, it makes almost drinking quality water, which is just wild.
00:40:15
John S
That's cool.
00:40:19
John S
Interesting.
00:40:19
johngrimsmo
Yeah.
00:40:21
John S
Have you, Haas had something on their site, I think it was called a coolant sterilizer, but it was, I don't remember if it wasn't what I thought or what, but isn't there a there, I'm sure there's a way of sterilizing water with ultraviolet light, is that correct?
00:40:37
johngrimsmo
There is. Yep. Yep. I looked into this hard a couple of years ago.
00:40:39
John S
just Does this work on coolant or does it only work on H2O?
00:40:44
johngrimsmo
It works way better on HTO. I talked to John Wiley from QualiKen about doing this on Coolant because he's one of the experts.
00:40:49
John S
Yeah.
00:40:51
johngrimsmo
on that um Coolant, the visibility of coolant is hard. So you almost need like a very flat, thin, you know, waterfall of coolant, like like a river, but very thin, like a millimeter thin for the UV light to be able to kill any bacteria within it.
00:40:56
John S
Oh, I see. Okay.
00:41:06
John S
Got it.
00:41:08
johngrimsmo
um So there there were some companies that were really playing with that. Maybe there's something there, but yeah, totally.
00:41:13
John S
No, I don't, we don't have this problem. I'm not going to worry about it, but the idea that if you could cycle through coolant and also hit it with a UV that kills any bacteria, that's obviously a great thing, but that also may explain why this isn't a thing yet.
00:41:22
johngrimsmo
Sure.
00:41:26
johngrimsmo
Yeah. Yeah. I think that's one of the reasons.
00:41:27
John S
Got it.
00:41:27
johngrimsmo
Yeah.
00:41:28
John S
Got it.
DIY Fixture Storage Solution
00:41:30
John S
Well, speaking of DIY, I gotta win.
00:41:32
johngrimsmo
ah Good.
00:41:35
John S
So we have all these VF2 fixtures, puck chuck fixtures. We wanted to store them. We were putting them on our wire racks that we have for lots of other reasons, but they don't sit great on these wire racks because they're to various sizes and weights and they're laying down flat and so forth. And so Alex had mocked up a, um it wasn't a bad design. It was going to use some send cut send bracket, gusseted brackets. We were going to buy drawer slides that were rated. And then you could, remember,
00:42:02
John S
you and I are old enough goingring up to going to the CD or tape cassette store and they had the posters usually. You could flip through the posters that were pivoted.
00:42:09
johngrimsmo
yeah yeah totally
00:42:10
John S
yeah um and So it could be like that, but it would be... it would just be on the wall or on a cart, and then you could flip through your fixture library and then slide the one out that you want and lift it off of the pull studs off of the send cut, send brackets.
00:42:27
John S
Well, before we click send on that, I was just like, okay, time out, stop. like What are we trying to do here? Because this is still a project.
00:42:34
John S
It's a lot of send cut, send parts. It's a lot of brackets. It's putting this together, blah, blah, blah. And I can't remember what the light bulb was, but I ended up finding a commercial grade, 500 pound capacity industrial clothing rack. It's actually even better. It's a dual rack. So it has a seven six, like 70 inches and half that 35 inch height broad across it. It's one of those Z racks. So in theory, you could nest them together, which doesn't matter for us.
00:42:34
johngrimsmo
Yeah, yeah, totally.
00:43:00
John S
and So I was like, 90 bucks, Amazon delivered.
00:43:03
johngrimsmo
No way.
00:43:04
John S
I was like, okay, great, I'm buying this and I'll figure something out. So it came and I just grabbed a coat hanger. And I was like, how do I make a coat hanger, hold this fixture? I just grabbed some paracord, put the paracord around the studs and around the, necked it around the coat hanger.
00:43:17
John S
And that worked, but of course, way too janky. But then I started it for 90 seconds and I was like, oh, I know what I need. And so I went, I wish I had one here to hold up for you. 3D printed,
00:43:29
John S
3D printed a custom hanger that is plenty thick enough to support the weight of the fixtures. And it's in the video shop up there.
00:43:37
johngrimsmo
Does it, okay.
00:43:38
John S
We just went and did.
00:43:40
John S
John. 10 out of 10, yes.
00:43:40
johngrimsmo
Does it hold up pull studs?
00:43:43
johngrimsmo
Yeah. Cool.
00:43:43
John S
It is like, they they the hanger part that goes around the rod is both thicker and wider so that it prevents any rocking or twist. So the once they're on there, they't they don't move around like a normal hanger would allow, and they're nice and clean, and we can put um we could put plastic dividers between them to to mitigate any risk that they were to bang into each other, but it's not even an issue yet.
00:43:55
johngrimsmo
Yeah.
00:44:07
John S
um it looks It looks dialed like it's a real win.
00:44:11
johngrimsmo
Cool. That's fantastic. I can't wait to see that shop update video.
00:44:14
John S
Yeah.
00:44:17
John S
Yeah.
00:44:20
John S
What's going on?
00:44:20
johngrimsmo
I will, I will wait for the algorithm to throw it on my homepage, which it will.
00:44:23
John S
Yeah. Oh, yeah. Well, likewise, I want to see your I want to see the current just just shedding tools.
00:44:30
johngrimsmo
Yeah. and And I filmed it in 4K on the GoPro, so hopefully Ryan can like super zoom in on that section, because it's way off in the corner of the shot. But I think i think it'll work good.
00:44:38
John S
Got it. the
00:44:40
johngrimsmo
So I will review that footage. Basically, I was in you know late last night. I left the cameras on the table going up the stairs so that Ryan would see them in the morning, our editor.
00:44:51
johngrimsmo
And and he texted me at 1 o'clock this afternoon. And he's like, OK, the video's put together. You want to check it out, or should I just post it?
00:44:59
John S
send it oh nice yeah that's great that's great yes great i got bit because uh we're trying to get some um
00:44:59
johngrimsmo
and No communication between us whatsoever. I just hear, here's the camera. And I was like, that is, that is what I was hoping for.
00:45:12
John S
You have some stuff going here. So I came back to run the Akuma after dinner one night, which I've been done a long time, and the door through that alarm again, which i I talked about this a long time ago.
00:45:23
John S
I'll keep it short. It is chips building up between the door and the machine.
00:45:26
johngrimsmo
Okay.
00:45:26
John S
I can only humbly assure you it is unbelievably quirky to figure out how they're like, it's like a triple nested snail U channel or hooked around it. And so Garrett built this great little tool that you can actually snake up behind it and you can now rake the chips all the way down that inside seam.
00:45:45
John S
You have to snake them straight down like four feet and then down an angled section and then down a straight section. The internal gasket that seals the door to the machine, we switched the cap screws out for thumb screws.
00:45:58
John S
So you can take it off without tools.
00:45:59
johngrimsmo
Yeah.
00:46:00
John S
And then we have, oh, what are the, hemostats, the pliers that like grippy like that.
00:46:05
John S
The medical pliers that, well, you could just use the needle nose, but the hemostats work a little better.
00:46:05
johngrimsmo
Okay.
00:46:07
johngrimsmo
Yeah.
00:46:11
John S
And then that lets you pick out the chips once you've flushed them all the way down there. So now that they have a process, it's it's really not bad. Oh, you got to climb in the machine to do that because you had to have the door shut. um But I kid you not, like of one of my adult life challenges, when that first started happening, you're like, because we kept, we kept snaking it and we like, there's no chips there, no chips there.
00:46:32
John S
Well, they were like further back behind this invisible gap.
00:46:33
johngrimsmo
Yeah. Is there no way to 3D print a seal for that gap or something?
00:46:40
John S
the The replacing the rubber seals would probably help, although I'm not convinced it would totally stop it. And they were also, I think they were like $1,700, which I'm just like, not a good use right now.
00:46:53
John S
um Doing a better job at knocking the ship's nest out, if it happens to build up there would help. And now, now that we know where it is and and how to fix it, you can fix it in probably four or five minutes.
00:47:06
John S
So it's not a, it's actually not a big deal anymore.
00:47:07
johngrimsmo
Okay. Is there a way to have a wash down line constantly on that area?
00:47:15
John S
You know, this is probably one of those things like the current where a lathe makes fun of you because it breaks all the time. The wash down is so good and that machine is so productive that I'm just, I've had found the weakest spot.
00:47:26
John S
It's, it's like, I really don't. Yes. Somebody should redesign that. It should be better, but like it's, it's just.
00:47:26
johngrimsmo
Sure.
00:47:32
johngrimsmo
<unk> There's no way for you to do it with like a hard brass line that you can bend into that corner or something and have the system pressure just point at it. I don't know.
00:47:41
John S
My only thought is we've turned off a couple of the wash down lines. That machine has a phenomenal flash, like shower cooler or on all of them.
00:47:46
johngrimsmo
Yep.
00:47:48
John S
We've turned off a couple to give us more pressure where we want it.
00:47:50
John S
So I don't really want to starve those because this is also like a, okay, every four times a year, we just need to clean it.
00:47:50
johngrimsmo
True.
00:47:57
John S
Like five minute things. It's not a big deal.
00:47:57
johngrimsmo
Yeah.
00:47:59
johngrimsmo
On this video, it came with, with washdowns and I don't think I've ever used it.
00:47:59
John S
I think.
00:48:04
John S
but Okay. That's funny. shit Um,
00:48:06
johngrimsmo
Yeah.
00:48:09
John S
Okay. We're, we're informally out of time, but I want to hear about the field next week. I want to talk to you about the DIY lady or machine that I'm not going to do, but I still want to talk about it.
00:48:18
johngrimsmo
Yeah. I love it.
00:48:18
John S
Um, yeah, what else?
00:48:20
johngrimsmo
Yeah. I mean, progress for the next week on the field should be significantly more than what it is right now.
00:48:25
John S
Good.
00:48:27
johngrimsmo
um A short story from this past week is I'm committing to doing a lot more hard milling on the blades. Actually, I'm hard milling the entire slot instead of just roughing it cold soft and then heat treating.
00:48:33
John S
Good.
00:48:39
John S
Interesting.
00:48:39
johngrimsmo
And then, yeah, and i have I have good reasons for that.
00:48:41
johngrimsmo
I'm going to do nice stay on that.
00:48:43
John S
I want to hear more about that.
00:48:44
johngrimsmo
um And I'm going to look into buying union tools as they're Japanese end mills that Adam the Machinist keeps recommending. Yeah.
00:48:53
John S
I'm only laughing because I got a quote on a one micron vertical machining center that I don't think we need it, but um could be dedicated for hard milling. And I also just bought my first and NS tools, which is what Hakko was recommending.
00:49:05
johngrimsmo
Yeah.
00:49:07
John S
Union tool looks like it's quite good as well.
00:49:08
johngrimsmo
Where'd you buy them from?
00:49:10
John S
um funny story, i wasn't matured I've matured beyond complaining about this stuff, but since you asked, found the tool, found what I thought would be part number, sent a articulate email to the sales people, being like, I think this is what I want, this the application, let me know, and they got right back away, but basically, I think it was a suggestion or whatever, and then it took over 36 hours with probably seven or eight emails to get the distributor to do it, including two, like not fun, one typo was the wrong quantity, one typo was our wrong name, just to get them bought.
00:49:47
John S
Just like, this is just so so ridiculous, sorry.
00:49:47
johngrimsmo
Oh, um, McMaster sells them.
00:49:54
John S
Thank you, that's actually great. Okay, yeah.
00:49:54
johngrimsmo
I don't know if it's exactly the one you want, but I bought, I bought CBN ball mill and corner radius and mill from McMaster.
00:50:00
johngrimsmo
They're like $200 or whatever. But, and lo and behold, and NS tool comes and I'm like, this is amazing.
00:50:05
John S
That's hilarious, wait a minute, okay.
00:50:06
johngrimsmo
Like, cause they're the best of the best theoretically.
00:50:09
John S
What diameter?
00:50:09
johngrimsmo
I like one mill.
00:50:11
John S
Okay. I bought four millimeter shanked, two millimeter bullnose cutting tool.
00:50:15
johngrimsmo
Something like that. Go to McMaster and just look, see if that has what you want.
00:50:17
John S
Okay. Yeah, I will.
00:50:20
johngrimsmo
um However, for Union Tool, I'm not exactly sure. There are some distributors that say they source it, but I don't know. Adam said, if you call them, they will sell via credit card.
00:50:30
johngrimsmo
and on the phone or something so i'm like i might just try it out i haven't done that but um prices aren't so bad and what's really cool is when a company specializes in hard mailing like ns or union their catalog tells you how to run this tool like specifically you go down 0.5 micron over so much and you'll get well over an hour or dozens of hours of tool life in these steels and it's just it's nice to be able to know
00:50:31
John S
Oh, interesting. Yeah. Yeah. Right.
00:50:46
John S
Yeah.
00:50:59
John S
What are you going to, what machine will you do that in?
00:51:01
johngrimsmo
ah let video
00:51:03
John S
Oh, interesting. Not that might not the current. Okay.
00:51:05
johngrimsmo
A runout would be my biggest concern, really, because everything's in an ER holder currently, so yeah, I could really go fix it or check the runout or something.
00:51:09
John S
We go fix it, right?
00:51:15
