johngrimsmo: Good morning and welcome to the Business of Machining episode 429. My name is John Grimsmo.
John: And my name is John Sonners.
johngrimsmo: And this is your weekly dose of manufacturing where John and John talk about kind of what's going on in their ever growing 10 year plus manufacturing business journeys.
John: I need this outlet partly because, you know, I just need like I create these lists and I get excited at the risk of saying I like talking about what I'm up to.
johngrimsmo: Yeah.
John: You don't even like that's the point, right? Yeah.
johngrimsmo: Yeah. Yeah.
John: yeah I have a bunch of, actually, I said to you just before hit record, had a few things. I had a bunch of things. Some of them are quick, I a bunch things. But how are you?
johngrimsmo: Excellent.
John: Good. How are you?
johngrimsmo: Yeah, i got I got a few things. um I'll start with over the weekend, Grayson and I went to the Toronto Timepiece show, which is a the you know the second annual Toronto watch show.
johngrimsmo: And they didn't really have them before that. ah So it was in a much bigger venue than it was last year. And it was just super enjoyable. Go walk around, talk to watchmakers, both big and small. um Some local Canadian guys, like Toronto guys that are you know importing either complete watches
John: Uh-huh.
johngrimsmo: from Switzerland or they designed it, Switzerland makes them, they import them, or maybe they put the final touches on it or whatever to the guys that are making, you know, 80 plus percent of the components themselves.
John: OK.
John: Legit. All
johngrimsmo: Yeah. For many many, many tens of thousands of dollars kind of thing. Um, it was really cool. It was eyeopening. It was really good. Um, these one, one company from Montreal is making a quartz watch, which is usually not that special, but solar powered.
johngrimsmo: And the dial, and then they explained it to me, like the dial is so thin that it's transparent and there's a solar cell underneath the dial, but it looks white.
John: right.
John: No. Oh, that's cool.
johngrimsmo: It looks totally white. And like Citizen and big companies have been doing this for a while, but they're trying to do it themselves, like small scale, grow big scale kind of thing.
John: Yeah.
johngrimsmo: And yeah, it was just super great to nerd out with the guy and, you know, talk about what's going on.
John: Yeah.
johngrimsmo: And typically I would totally discount quartz watches because I'm now so into mechanical watches that I'm like, okay, but this is actually kind of cool. and they look really good. And he said, you could hide in a cave for 364 days a year and it'll it'll run.
johngrimsmo: And then one hour it'll charge it from sunlight.
John: No. For a year?
johngrimsmo: Yeah. Yeah. Yeah.
John: That's cool. the like the The whole like the fact that mechanical watches function as a battery to me is bueno.
johngrimsmo: Mm-hmm.
John: It's really cool.
johngrimsmo: Yep. And then one of the guys that listens to our podcast and is in Switzerland, Torsti Lane, Lane Watches.
John: Yeah.
John: Yeah.
johngrimsmo: um I got to meet him. he didn't get a table. He had just invited people to his hotel room kind of thing.
John: Oh, yeah.
johngrimsmo: which was cool. It actually worked really well. He got like the deluxe suite with the table and all his brochures were out and everything.
John: Yeah.
johngrimsmo: And so Grace and I just had like an hour long, super close, like question session with this expert watchmaker from originally from Finland, but now in Switzerland, he like moved his whole family to Switzerland to pursue watchmaking.
johngrimsmo: Cause he's like, if you want to make it, you're going go to the Mecca and and do it.
John: yeah
johngrimsmo: And some of the things like I've heard stories, but to hear it firsthand, he's like, If you're not Swiss, they won't sell you parts.
John: Well, that's kind of what, i don't to put words in his mouth, that's kind of what our Australian friend said seven years seven years ago when I met him.
johngrimsmo: Exactly. Yeah.
John: Yeah. Yeah.
johngrimsmo: Yeah.
John: it's ah
johngrimsmo: And Torsti was like, ah you know, even moving here. It like helps a little bit, but it's not a green light to like buy whatever you want. and it's like It's weird. so
John: yeah
johngrimsmo: But it was cool. um It was great. His work is phenomenally, absolutely next level. Just gorgeous, beautiful, very inspiring. and
John: What was the name of it again?
johngrimsmo: ah Lane, L-A-I-N-E watches.
John: Lane watchers. if I'll take a look too.
johngrimsmo: Yeah. Yeah, just take a look. and It's just beautiful, beautiful stuff.
John: Sure. Sure.
johngrimsmo: And I complimented him on his Instagram, like filming and the way he macro videos the watches. And I'm like, I watch everyone. It's like just so nice. um And you're familiar with Guillaume
John: The engine turning.
johngrimsmo: The
John: Mm-hmm.
johngrimsmo: Engine tree, exactly. Putting the beautiful decorative finishes. So he's got some old, um you know, 100 year old lathes or whatever that to do that.
John: Oh,
johngrimsmo: And he's quite the master at it. But he said it's very repetitive. So he's like, I'll just sit there listening to business and machining, like repeating these, these same things. And he's like, you know, it's like 123, you know, re rack or whatever you call it back to zero 123. And if you go for you've screwed up the whole part.
John: right, right, right.
johngrimsmo: It's just like doing that for two hours straight. Just one, two, three, one, two, three, one, two, three. And if you lose count, if you lose concentration, if whatever. So
John: Oh, I can't not say it. That's got to be a CNC automated.
johngrimsmo: I know. So we had a long conversation about that and it's, it's scraping basically.
John: Yeah.
johngrimsmo: That's, that's the benefit of doing it like that. And like Hako has transformed his current to do scraping. Um,
John: Yeah.
johngrimsmo: spindle rotating controlled thing but uh it's a lot of a lot of effort to upgrade like his current my current to do that there's like weird stuff that has to be done um no but but uh sorry hacko does yeah yeah um but yeah anyway
John: Yes.
John: Mm-hmm.
John: Lean watches has a current. Oh, sorry. his' Okay, sorry. Yeah, sure, sure.
John: The idea too of like, it's kind of full circle to me of... you build a little machine, an engine, a guilloche is perfect because it doesn't have to be, it doesn't have to be terribly rigid or terribly accurate.
johngrimsmo: Yeah.
John: And then you have a, you know, a cam or some sort of a control system or a code, and then you can even have interval set up So it's like, okay, here's my x-way pattern and here's my interval where I go.
John: um We actually, I think did this years ago on the Tormach with a little experiment where every four intervals, it would go over and re-dip the rubber tool like a really hard rubber tool in a, um ah what do you call it?
johngrimsmo: oh
John: Like a compound. I can't think of the name. Grit.
johngrimsmo: yeah
John: the Sandpaper compound. Sorry, lapping, whatever. Anyway, really cool.
johngrimsmo: Yep. So that's like using a Kraytex or a rubber eraser or whatever, where you're just going vertical, like dot, dot, dot, dot. dot Right.
John: Yeah, correct.
johngrimsmo: Whereas guillotine is more like scribing and scraping along a circular or a linear pattern or whatever.
John: Okay. Okay.
johngrimsmo: um
John: Yes.
johngrimsmo: But all all kinds of different ways to decorate the, decorate the onion kind of thing. But, um but yeah, it was great.
John: Yeah.
johngrimsmo: was super fun.
John: I had to laugh last week when you spilled the beans on your love of watches.
johngrimsmo: Yeah.
John: So, you know, I've been talking about sort of on a personal side, you know getting the phones out of our bedroom and like detaching from them and all that. I still want to wait to tell what time it is in the bedroom, especially because, yeah, i wake the of the lot times in these restrooms.
johngrimsmo: e
John: Sometimes I'm like, is it 10 minutes before my alarm's going off or is it four hours?
johngrimsmo: Yeah.
John: And so I thought, oh, I bought a watch from, um 20 some years ago, I just graduated. i i stumbled across it in a store.
johngrimsmo: Okay.
John: I immediately fell in love. It's one of the rare times in my life where I've just immediately seen something and won it. And at the time was maybe $800. So it was a huge purchase at the time.
johngrimsmo: Totally.
John: And it's from, ah so I believe this was company called Zemex, Z-E-M-E-X.
johngrimsmo: Okay.
John: I am certain it's quartz because it takes a battery and it's whatever.
johngrimsmo: Yep.
John: um the The motion is also that quartz like chunky.
johngrimsmo: Every second, yeah, tick, tick, tick, yep.
John: is Yeah, yeah. But I still love the look of it. And it sat unused for 10 years in a drawer. And I thought, well, there you go, John, just use the watch. So.
John: Pure coincidence. I'm just laughing because i I enjoy these nuggets of our stories over the years. I haven't touched a mechanical watch in 10 years. And that one day you say it, that watch is on my desk. I had 3D printed a tool to remove the back casing um to expose the battery, which worked.
johngrimsmo: Okay.
John: And had a little O-ring that was like pretty much trash, but I'm going to go underwater with it.
johngrimsmo: Yep.
John: So who cares? and And I replaced the battery, which is like not even remotely a legitimate watch task, but only compared to mechanical stuff, but it was fun.
johngrimsmo: Nice.
johngrimsmo: Nice. Exactly.
John: Yeah.
johngrimsmo: and And there's, there's a we're also used to using our phones or computers or whatever to tell what time it is. There is a unit task beauty to a wristwatch that it's, that's all it does.
John: Yeah.
johngrimsmo: Like I i used to have a smartwatch back in 2017 or whatever. And I, once it broke, I stopped caring. I'm like, I don't, I don't want notifications on my wrist. I don't want any distractions. I don't want anything. So to have this beautiful piece of mechanical art that just does one thing, i love it.
John: Yes, that's awesome. What wear now?
johngrimsmo: ah Now I'm wearing a 1990 Oris that I picked up at a flea market for $360.
John: Okay. Yeah.
johngrimsmo: And I had a cracked crystal. I replaced the crystal. I did a full service on the movement. and Now it runs. It doesn't run perfectly. I think I was two minutes fast the other like when I checked it yesterday. And I was like, no, that's not good.
John: After how long?
johngrimsmo: It's been a couple weeks since I've touched it.
John: Oh, it doesn't seem to a bore.
johngrimsmo: But like like, I have a time grapher that that you put the watch on. It's like an acoustic microphone that senses all the ticks. It's pretty cool.
John: You really are further down this rabbit hole.
johngrimsmo: um Oh, I'm so deep down it. And I don't know, it runs good on the time grapher, but different in real life. So like I did something wrong or need to polish something that I didn't or need to loop something that I didn't or use too much or i don't know.
johngrimsmo: There's a lot to learn. you know You think you got your head wrapped around it and then you get actual results from your work.
John: yeah
johngrimsmo: And you're like, no, there's way more. like That's why people study for 10 years to do this.
John: Yeah. Yeah.
johngrimsmo: I'm just playing.
John: But that's what seems, um that's what seems appealing. i don't have ah desire myself, but it so it does seem appealing is that it seems like you could choose how much you want to take on, like just servicing a fleas market watch or building a watch with off the shelf components.
johngrimsmo: Yeah.
John: And then you start making individual ones and swapping like that's cool.
johngrimsmo: Yes.
johngrimsmo: Yeah, it is la carte, which is super cool. ah Depending on availability of what you want to do and the market and things like that.
John: Yeah.
johngrimsmo: um Yeah, that's fun.
John: The other funny or coincidence to this is if you take your arm and you hold your arm straight out level with the ground, you're right.
johngrimsmo: you
johngrimsmo: In front of you?
John: great So that's john that's Johnny Five's arm, right?
johngrimsmo: Yeah.
John: And there's a motor, there's a gear motor in his shoulder that controls his arm pivoting um you know down and up, which is a lot of torque on a whatever, ten eight millimeter shaft of that gear motor.
johngrimsmo: Okay.
johngrimsmo: i
John: and Springs are a wonderful device to help soak up ah some of that required torque. And so the way the inputting team built this is it uses a grandfather clock mainspring, which is powerful enough that when you buy it and you cut open the ah snip off the wires that hold the mainspring, you have to be careful it doesn't
johngrimsmo: No way.
John: like hurt you.
johngrimsmo: No way.
John: it's It's probably eighth inch thick steel, something like 12 mil, eighth inch, or sorry, half inch or 12 mil meters wide.
johngrimsmo: Oh, geez.
John: And it's probably four or five inches in diameter with, with I don't know, eight or 10, what you call spring loops, if you look, coil, thank you.
johngrimsmo: Coils. Yep.
John: And so um just actually, mean, I made great progress this past week on J5, which felt really good.
johngrimsmo: Nice.
John: And one of the things i I had installed the springs, but I hadn't preloaded them. And so I'm finally ready to start testing the motor functionality and the motor does not have enough torque to to lift the arm on its own.
johngrimsmo: Hmm.
John: Well, and don't think it does, certainly not in a fluid way. So what you do when you're ready is there's two, um there's a drive plate that has two screws that act as pins in it. You pull those screws out and then you you like wind up the arm.
johngrimsmo: oh
John: I think it went two or three rotations that compresses that spring.
johngrimsmo: Yeah.
John: And then unfortunately the arm, i there there's some question of what spring to use and what's available. It's it's a little bit frustrating. and um i I think mine should be a little bit more, have more power and it doesn't.
John: So the arm is not perfectly, I would say buoyant. i don't know what that word is, but it's close.
johngrimsmo: Yeah.
John: And now the motor definitely can can lift and lower the arm.
johngrimsmo: That is really, really cool.
John: Right?
johngrimsmo: Yeah.
John: I'll post a, uh, this Friday when this airs, I'll post an IG of the, um, of the arm.
johngrimsmo: please Yeah, and it it stays loaded. like It's not like a watch mainspring that unwinds over time. You're just preloading it two or three turns, and now it's lifting the arm by itself.
John: Yeah. The equivalent, guess the analogy would be like a tool balancer that hangs from the ceiling and where the tool, the eight pound tool is now weightless.
johngrimsmo: Yep. Cool.
John: Yeah, that's fun.
John: um
johngrimsmo: would What you got going on?
John: if you would what's Okay, here's my here's my, okay, one ah one one other Johnny Five thing I wanted to just share.
johngrimsmo: Thank
John: There's a ton of instances where you do have to use little bits of super glue, mostly around putting magnets into 3D printed ah parts that have pockets for the magnets that allow the covers to attach and detach.
John: um There isn't a lot of other super glue in terms of like, it's not a super glue build. Like it's a structural build that has fasteners, et cetera, et cetera. But nevertheless, there's quite a few instances where you're using super glue. And do you know about the baking soda trick?
johngrimsmo: ah Yes, from 1998, building RC airplanes. I learned the super glue and baking soda trick.
John: Okay. I want to hear what you how you explain it.
johngrimsmo: So yeah, building airplanes, if you need to fill a gap, you just literally sprinkle a bunch of baking soda in the gap and then put thin CA glue and it fills it, makes it hard, still grips to everything. And it's a total gap filler.
johngrimsmo: So yeah, I did learn that trick when I was like 13.
John: Awesome. um
johngrimsmo: But I've never told anybody.
John: Well, that's the thing too. It's like, if this helps one person. um So yes, it's great to help with as like a filler. But um the key thing that I like is that it basically, it acts as a catalyst and it significantly accelerates the curing.
John: I'm reading now from a Google spot.
johngrimsmo: Interesting.
John: It basically hardens instantly, which I care about because I put these magnets in and the magnets are, somewhere between a slip fit and a press fit, but it's needs some adhesion, but I want this done. Like i want to push the magnet in cause sometimes there's tape, eight magnets and I don't want the uncured super glue to then get on my fingers and all that.
johngrimsmo: Yeah.
John: And so I just have a little plastic jar of baking soda. You sprinkle a little bit on it's instantly hard. You can then tip it over, dump the extra back into the container or in the trash.
johngrimsmo: So it, it, uh, catalyzes the the reaction to start faster.
John: The reaction is due to bicarbonate molecules in the baking soda reacting with the cryo cyanacrylate, creating a reactive ion that promotes faster polarization to a strong durable bond.
johngrimsmo: Yeah.
John: I believe it also increases the strength of the glue.
johngrimsmo: Interesting.
John: Can be used as a structural filler or to strengthen joints. Minimizes shrinkage compared to CA glue curing on its own. But it is exothermic, so it creates heat. and ah so But it's like, it's great. I love it.
johngrimsmo: because i've I've used thin CA glue and it kind of stays wet for longer than you want it to if you have a glob of it or whatever. I did not know you could use a sprinkle to to kickstart it.
John: Yep, yep.
johngrimsmo: That's cool.
John: And it's way easier, like primers are, first off, it's another thing you gotta buy and have around or spray or put on.
johngrimsmo: Yeah, I do have the activator spray. I quite like that.
John: Well, I don't because sometimes The activator spray means as soon as the twos are joined together, they're done.
johngrimsmo: Yeah.
John: Sometimes you can't even get the thing like pushed in.
johngrimsmo: Yeah, like aligned or flat. Yeah.
John: Yeah. So the base was nice because you just sprinkle on when you're ready. And I believe many or most of the primers or accelerators we weaken the bot.
John: Not that that matters for 3D printed covers, but um it's been a real win.
johngrimsmo: you
johngrimsmo: That's super cool.
John: Um, and then ah other real quick one is I really love my computer. It's been another full kind of week having it.
johngrimsmo: The new, yeah.
John: Um, yeah, I don't remember if we, if I shared anything about this, but there was a mistake and they gave me 32 gigs of RAM. It was supposed to be 64.
John: So they just came out and swapped those sticks out because I was getting a memory error and in the Johnny five model, but it's, that's cause it's massive.
johngrimsmo: Yeah.
John: Um, but now I can open it, but um I'm going to put up an Instagram of all the specs, if anybody cares. The other thing I just learned, which I'm just going to share it, it kind of stinks if it's true, but I'm also happy.
John: But Instagram folks, gentlemen reached out and said, um if you can get rid of your RTX gaming, it's a graphics card, which I got the 5060. It's a gaming card um that's really good, but it doesn't offer as much benefit as a Quadro card does with things like Fusion, where it allows...
John: um the graphics card is able to then help support the CPU and computation. So I'll just leave that out there. I'm only a little bit frustrated because I tried to do this research ahead of time and ask people, reach out, Google around, et cetera.
John: And I didn't hear that. Like, that's kind of what I wanted to know. Like, just tell me what to buy.
johngrimsmo: Yeah.
John: And if you go to the Autodesk site, they list 783 graphics cards.
johngrimsmo: yeah
John: It's like, no, just tell me like, tell me four.
johngrimsmo: And and the the quick answer as to why this matters, you know why does RAM matter?
John: Yeah, right. That's great.
johngrimsmo: What does the graphic card matter? Things like that. yeah A while ago, there was people were kicking around a benchmark test. I never looked into it. Yep.
John: So I reached out to PDXCNC who did all that and he did a great job, but he um was kind of like, I don't think he's given it a lot of love lately and he was mostly focused on Mac stuff.
johngrimsmo: Yeah.
John: And again, not a great answer, but I don't really care. I just needed like a seven year upgrade. And this thing is, this thing is my kids would say, bussing, bussing.
johngrimsmo: That's awesome.
John: Um, it wasn't, I mean, the whole computer, like case power supply, solid graphics card, terabyte, SD, whole thing was under two grand. Like it wasn't, wasn't like I spent so what I think is an inordinate amount of money on some like mainframe desktop power PC, whatever.
johngrimsmo: Okay.
johngrimsmo: Right.
John: It's like, I mean, yeah. but month
johngrimsmo: Not like Amish building a $100,000 for Linux. Yeah, yeah. pc for linux
John: Yes. That was crazy. That was a while back too.
johngrimsmo: yeah um I do have another glue point actually.
John: Um,
John: Shoot.
johngrimsmo: So I've always wanted to make a glue fixture. So watchmakers use these all the time. It's like so a small fixture with a grid pattern in it.
John: Yep.
johngrimsmo: um And then you glue your part right onto it. And for years after you, I've done the you know double-sided tape or two pieces of tape with the glue in the middle kind of thing.
John: Yep.
johngrimsmo: But a glue fixture is a metal flat thing that you glue your part onto.
John: OK.
johngrimsmo: And I had, what was I making? Oh, I wanted to blank out um a chunk a leftover chunk of damasteel into pocket clips.
John: and
johngrimsmo: And so I made my glue fixture, made it really good for fun. Me and Steve lapped it like really flat and shiny. um And then I glue my part on and I go, I, earlier that day I had made the glue fixture and then I go to make it and I cut the parts. And because it's glued down, I'm like, how rough, how aggressive can I go?
johngrimsmo: ah you know, so I went light. I used a high feet end mill that pushes downwards, not sideways kind of thing.
John: Yep. Come
johngrimsmo: And then for the last 10 thou, I kind of kissed it one thou at a time with a small end mill. just to like not put any sideways force and throw my parts.
John: here.
johngrimsmo: And it worked. It took a long time, like 45 minutes to do what shouldn't take that long but whatever it worked but I cut into my glue fixture by seven thou and I was like no I programmed this to be three thou over why are you ten thou lower than that on the speedio and so there's an error somewhere either in my tool touch off or maybe I didn't touch off the tool or something and I haven't fully dug into it yet but um
John: Come here.
John: Come here. Come here.
John: What was your ZDAM?
johngrimsmo: um fixture origins of like the bottom of the Aeroa.
John: Yeah.
johngrimsmo: but But I made the fixture to that datum, right?
John: Okay. That's a good rebuttal. That's a good rebuttal.
johngrimsmo: Yeah, exactly.
John: Yeah.
johngrimsmo: And, uh, and i retouched off the tool that made the fixture and it was with intense. And then I retouched off my cutting tool for the parts and it was off by like 5,000, which is like, what the heck?
johngrimsmo: Maybe I didn't touch it off. I don't remember. Um, this weird stuff like that.
John: Okay.
johngrimsmo: Like I don't, I don't spend all day, every day making new stuff like prototypes and, you know, so I'm
John: hook
johngrimsmo: I feel really bad when I make dumb mistakes like that, or or I can't figure out what the problem was. I'm like, shouldn't I be able to do this better?
John: Yeah.
johngrimsmo: But it's it's fun. It's good.
John: did it Did the fact that it cut into your fixture cause any problems other than the emotional scarring?
johngrimsmo: My pride. Yeah.
John: Yeah. Yeah.
johngrimsmo: and And I can very easily just make it again 10,000 deeper. um
John: yeah
johngrimsmo: So like, whatever. But still, I'm like, what the heck? No.
John: I watch, still watch most click spring videos. And he does this, he uses those on his little micro lathe where he'll have a, sometimes he'll dimple in the center of the part and then he'll use his tailstock to push it into the grid, like the waffle iron with the super glue.
johngrimsmo: any
johngrimsmo: oh yep
John: And then it'll hold no tape, like just direct super glue of the brass part on the, I don't aluminum or steel fixture.
johngrimsmo: yeah
John: And then he can turn the full side full face. it works great.
johngrimsmo: turning with superglue that's crazy yeah yeah your favorite um yeah and i'm using have you ever used the black ca glue
John: Yeah, he uses a lathe, which is a bummer. yeah
John: um Black Max.
johngrimsmo: Black Max, yeah. So Loctite 380, 480, or the new one I just learned about give me second, 438.
John: I do have some of Wait, 480 and then 438?
johngrimsmo: 438 and 380. Okay.
johngrimsmo: four thirty eight and three eighty
John: So I own 380, which I didn't know there were other versions.
johngrimsmo: Exactly. and It's like, there's there's like 20 more, but those are the big ones.
John: Touche.
johngrimsmo: And they're all like slightly different formulations of whatever. I think 380 is, that's also what I have. It's like the bread and butter. Like, yeah, it's not cheap.
John: Yeah. It's not cheap, by the way.
johngrimsmo: Small bottle, it's like 20, 30 bucks or something like that for a small one.
John: Yeah.
johngrimsmo: But it's rubber toughened apparently. And it just adds a bit more cushion, not the the hard shock of a super hard clear CA.
John: Okay.
johngrimsmo: So it can help for stuff like that.
John: Yeah. No, but I keep the 380 we have is over by the Tormach because that's what we would use for super gluing on real stuff. And then i I chew, I mean, it's probably silly to be this frugal, but I use just regular old, uh,
John: Loctite brand. i had a my draw
johngrimsmo: Like superglue?
John: ah use this. Yeah, well, but I'm picky.
johngrimsmo: excellent
John: I don't like that. We used to so often i used to use the I know you probably can't hear me when i turn around. They would sell these 10 packs of like disposable, the little mini toothpaste tube ones.
johngrimsmo: Okay, yeah.
John: And I get tired of those. They like break out the backside and all all that.
johngrimsmo: Yeah, I don't use those. I use the big, like bigger bottles, like bigger than that even.
John: Oh, really?
johngrimsmo: Yeah. Yeah.
John: I like, I like this Loctite it's on Amazon. It's 20 grams and it's not the gel. I don't like the gel usually. And what I like about this is it seems like the sweet spot size, because this will last me six months or a year it's it's eight bucks or something.
John: And then it doesn't get on your fingers. The cap is pretty good. And I don't really want to keep super glue for like three years. Cause I feel like it's, you know what mean?
johngrimsmo: yeah
John: Anyway.
johngrimsmo: Yeah, and then what the watchmakers do is they'll take the whole glue fixture and dump it in acetone and it dissolves. And that's what the grooves in the fixture are for so that the acetone can start to attack the sides.
johngrimsmo: And i was reading, if you scratch the side before the acetone attacks it, you're now opening a a path for the decrystallization depolymerization process to begin.
John: Interesting.
johngrimsmo: or in the acetone can attack it a little bit faster and it worked extremely well. um I just had like a little yogurt tub that was upside down with a quarter inch of acetone in the bottom and soaked my part and it's like within 20 minutes, it was completely off and then another 20 minutes and it's pretty much like toothbrush dissolvable after that.
John: yeah
John: I wonder if... um I wonder if you could put your part in a glass mason jar of acetone and put the whole mason jar inside and ultrasonic.
johngrimsmo: Yes, you absolutely could.
John: I just cleaned Yvonne's like wedding ring and I have a little, uh, it's my absolutely disgustingly filthy gun, um firearms, ultrasonic.
johngrimsmo: Nice.
johngrimsmo: Okay.
John: Like, i mean, it has just a carbon buildup that looks terrible, but like, okay, you put it in a little, uh, you put the, uh, the ring in a, uh, of, uh, I think it's DNA alcohol.
johngrimsmo: A little jar.
John: It works great.
johngrimsmo: yup ye Yeah, I did that to Meg's wedding ring too and I put it under the microscope and I'm sending her pictures from work and um she's like, I didn't even know it was that shiny. Like, holy cow, look at all the details.
John: That's hilarious.
johngrimsmo: Yeah.
John: Tell me you need your wedding ring for the white light interferometer.
johngrimsmo: Oh, I actually thought about scanning a diamond with that. It would be amazing. I'm like, oh I'm 100% doing that.
John: The most expensive part of that bill becomes the divorce.
johngrimsmo: yeah Exactly.
johngrimsmo: So, I mean, I'm happy to talk about the white light enderometer as my next point.
John: I was setting you up.
johngrimsmo: So the past week um I didn't go hardware, I went software. So I wanted to wrap my head around the computer side of what's required for this. And thankfully Cyrus put up a um Google Drive folder with some of his video files.
John: Okay.
johngrimsmo: So like you build a device and it's basically, you know, ah LED bounces off a beam splitter, goes down to your part, reflects off your part, goes back to the camera.
John: Okay.
johngrimsmo: And the LED also goes to a reference mirror and then back to the beam splitter and then up to your camera. And the interaction between the two arms um interferes the wavelengths and like shows fringes, basically.
John: I understand what you're saying, but like, I don't, okay.
johngrimsmo: is Yeah, it's quick and dirty. it It'll be easier to explain when I make a video of it. but So that's the hardware side of it. um And Cyrus already has video files recorded from his device that are just publicly available to use.
johngrimsmo: um
John: Phenomenal.
johngrimsmo: So I downloaded them and I'm like, sweet, now I don't need to do the hardware side to test the software side because I have valid video files.
John: Oh, you can just use his as if it were as as as a surrogate.
johngrimsmo: ah could be Exactly.
John: Oh, that's cool.
johngrimsmo: Exactly.
John: Sure, sure, sure.
johngrimsmo: So I can piecemeal my project as I want to, as I want to spend money or time or whatever. um And he used a program called Math Lab, which is like a big, fancy, scientific, like expensive, multi-thousand-dollar-a-year kind of program.
John: man Okay.
johngrimsmo: um There's an open source one called Octave that does almost the same thing. And I'm sitting there with ChatGPT for hours and hours, like basically writing my own conversion script to get from this video file.
johngrimsmo: And it scans through every frame, every single pixel on the screen for light, dark intensity, watching the...
John: Oh my God. You need a new computer.
johngrimsmo: yeah watching the fringes pass across the part and knowing what's high and what's low and it's pretty interesting how it does it and i've got that almost fully working
John: Yeah.
johngrimsmo: um And when I figured out the other days, you need another program called Gwydion that interprets the results from that and actually makes you a visual 3D map. And you can do a section view.
johngrimsmo: You can say, show me a cross section between this point and this point. And it'll give you like um like a heartbeat monitor, like ding, ding, ding of a cross section height map of your part.
John: OK.
John: OK.
johngrimsmo: So imagine you you put a 3D milled surface on there and you're like, how deep are the cusps of every ball mill?
John: Yeah.
John: it's just It's a second, literally section view.
johngrimsmo: is section view. Yep. And I'm like, Oh my gosh, this is gonna be so amazing.
John: Okay.
johngrimsmo: So I'm converting his files into that into that into that. And I'm getting like, actual results from this. And it is getting real exciting real fast.
John: Good. That's sorry. That's incredible.
johngrimsmo: Yeah. and And now as I come to work, and I do my work, and I'm like, man, if I had that thing right now, i would be using it, man, if I had that thing, I'd be using it like literally five times a day.
John: Yeah.
johngrimsmo: um So the one I'm building, I'm going to attach to my Zeiss microscope to save some time and money. But then can't help but think of like, what is a little tiny, you know, one foot by one foot cubed microscope interferometer size 3D printed device that I could make this open source, you know?
John: yeah yeah
johngrimsmo: Because for me it to attach it to my relatively specialized size microscope, like nobody else is going to do that exactly. So And I'm probably going to want more than one if this works really well, like one in the front shop kind of thing.
John: yeah
johngrimsmo: So like there could be the next phase is to build an open source like kit. Not that I'm going to supply it, but I'll put the bill of materials up in my notes and videos kind of thing, right?
John: But feels like the perfect thing where other people are probably going to be more willing to to share, pay for make it better. Because the reality is like you could pour four years into this and the reality is getting one month of feedback from other people is going to be a better.
johngrimsmo: Yeah.
johngrimsmo: that's That's a really good point, yeah.
John: Yeah, that's awesome.
johngrimsmo: yeah it's the i want one at home like it's it's gonna be really really really cool
John: The two things that are blowing up in my head are number one, your diffraction limited YouTube guy that blew me away.
johngrimsmo: yeah yeah you saw the micro manipulator video
John: And number two, Ren Zeddy. Yes. Incredible. I don't even think we should talk about it because it's just, I'm going to say it's such a strong, and i mean, you already mentioned it and I'm not going to double down as such a strong endorsement.
John: Maybe we can throw the link in the video notes.
johngrimsmo: Yeah, i'll I'll do that.
John: Um, or just if you Google search, uh, or YouTube search for, I believe it was called, um, diffraction limited, not unlimited diffraction limited.
johngrimsmo: Yeah. Correct.
John: um
johngrimsmo: And it's um what's called 3D printed micro manipulator is this big video, but
John: yeah
John: incredible.
johngrimsmo: Everybody listening to this will get a kick out of at least peeking at the video, whether you watch the whole 20 minutes or not. But like, it's really cool. And it's a great edit and a great narration and like, so good.
John: It's a like, I shouldn't say this out loud, but like continuing last week's kind of question of like, should we post more content?
johngrimsmo: Exactly.
John: i'm like, no guys like that are doing it a hundred times better than I would.
johngrimsmo: it exactly
John: So I'm going to just be a consumer of this content. um But the other one is in typical fashion, Renzetti put up a phenomenal video on Instagram this morning. You absolutely need to watch it.
johngrimsmo: I saw that. ah sorry I saw it. I saw it.
John: Tormach lathe tool setter. I'm like, what is he doing? I'm thinking like, is he built like a touch out, a touch probe that swings out? Nope. It is a kinematic three point mount that's removable with a carbon fiber tube that holds this um off the shelf, uh,
johngrimsmo: Amscope. Microscope.
John: Thank you.
johngrimsmo: Yep.
John: Yes. And it lets him look at his cutting tool. And i not not that I had any doubt in my head because Robin's so good at what he does, but I wasn't really sure how, you know, like when you walk up to an optical comparator, I think many of us could get different answers on an optical comparator of ah of ah parts.
johngrimsmo: Yeah,
John: yeah The way Robin showed this through his camera, it's like, oh, that is dialed.
johngrimsmo: yeah he said it's like an 80 times zoom like lens and how he kind of self centered it by putting a wiggler in there and like, yeah, the three point kinematic mounts with a big magnet to hold it down and the cathedral arch.
John: Holy cow.
John: Yeah. Yeah.
John: The arch, what was it called? Like the cathedral arch dome balls.
johngrimsmo: Yeah.
John: So that's like the contact patch point is, yeah.
johngrimsmo: So the Hertzian contact is more spread out across the, and I'm like, you, him just explaining what he's already done teaches guys like us, like how to do more things.
John: Yeah. yeah
johngrimsmo: Like. Hmm.
John: You know, it's interesting you say that. I'm inclined to agree. i also think to some extent it's so intimidating that it also may be a bear. i don't mean this is in any way to throw shade at Robin or to say he shouldn't stop doing it, but I don't know that guys like him appreciate how far they've come. And it is a little bit of like, I'm not going to count.
John: Like he's shown in his videos, like how to contact, how to calculate the effects of gravity on a ah carbide tooling ball. Like that's, First of all, it's almost completely irrelevant for many of our applications in our lives.
johngrimsmo: But you never know. And even just that video he watched, i took takeaways from that that I will probably use at some point um or at least reference back to, you know, it's like and you don't know whatever you post, you don't know what it's going to hit, who it's going to hit, how it's going to hit, you know.
John: I know.
John: you know Which is great, which is great.
John: Right, right. No, and no, no, sorry. I feel like I'm making a mistake by saying this. I don't mean to imply that Robin should tone it down at all.
johngrimsmo: No, of course.
John: I just mean it is, it can be tough to follow along. and But what i love about Robin is he's never saying a single thing because he wants you to be impressed by him. We all know there's people that are like, I need to flex on you by telling you how much I know.
johngrimsmo: No.
John: It's not, it's Robin is so wholesome and it's so good, but it is, it can be tough to follow. um
johngrimsmo: Yeah.
John: and At least for a guy like me.
johngrimsmo: Yeah, he put up a, he was making what a cylindrical grinding ah thing, one of his YouTube videos, which is basically like a flat fourth axis for a surface grinder that will spin parts.
johngrimsmo: And he shows how he makes it and how he measures every needle bearing and like it intersperses them and all this stuff. And had to watch that video twice to really understand it.
John: Yeah.
johngrimsmo: But i was like, holy God, this is amazing.
John: Incredible.
johngrimsmo: And that's just what what he does and has been doing for million years.
John: Yeah. in The world.
John: Yes.
John: um Okay. are we Are we ready for just, are we ready to wait for next week to talk more about the white light interferometer? Is there more talk about now?
johngrimsmo: i'm I'm pretty good, yeah.
John: Okay. We have, ah there's two Lex updates I want to share that are worth sharing. And then also I got to give a tip of the hat to AI. Sorry, Meg. um We, I had this on my, to sort of like,
John: half active, half passive to do list. And then Rob Lockwood made a comment that pushed me over the edge, which was notebook LM. So I actually started to make my own little cheat sheet of what i what are different AIs good for, because i'm not I'm not an expert, but I'm an active consumer.
John: So ChatGPT is what I use every day. um Claude is apparently the best for programming code. um Alex here was saying that chat is really good at creating images, but but Gemini is better at editing images.
John: just throw i up Don't take that as gospel. And then um Notebook LM, which is a Google product, and I first came across it a while back because it's the one where you could put...
John: The example we did was we put links to national parks and and other stuff about national parks and it creates an NPR style podcast within like five minutes of two people bantering back and forth in an NPR fashion about like, if you've not seen this,
johngrimsmo: What? Actual audio?
John: Yes, John, complete. I mean, you would never know it wasn't real. if Like if I hopped in the car with you and turn that on, you would never be like, John, is this fake?
johngrimsmo: Yeah.
John: Like it's laughing banter. I'll send one to you when we hang up because it really is um just too cool.
johngrimsmo: No way.
johngrimsmo: That's wild.
John: But what Notebook LM seems to be good at for reasons I can't explain is Parsing through docs. So I uploaded all 20 of our Okuma horizontal PDFs, which printed out are probably four feet tall.
johngrimsmo: Yeah.
John: Like it's rivaling the intro guide to a FANUC manual and and uploaded it.
johngrimsmo: Yeah, yeah.
John: i don't know, maybe waited 10 minutes. And then I typed in a question. i was like, hey, how do I do this on this machine?
johngrimsmo: Oh, sure?
John: It responded with eloquent three different ways to do it with all cited references. John. I mean, it kind of goes back to the current schematic.
John: It's like, where does this pump deadhead like electrically?
johngrimsmo: Yeah.
John: Like it's just insane.
johngrimsmo: And the the sites are amazing because then you could just like go to page 457 and be like, oh, that's what you mean.
John: Boom.
johngrimsmo: okay
John: Yep.
johngrimsmo: wow
John: The other one is we figured out um that we can put, because we use our internal wiki through Google Sites, um but it's it's a protected thing that you have to be on our Sonar's domain to access for because it's an internal private wiki.
johngrimsmo: but
John: We could put Gemini, I say Gemini, oh wait, I say, whatever, don't care how you pronounce Alex figured out how to hook up Gemini. so now our wiki, which the point of the wiki was to be and a place to dump information. And then the fact that it's Google search means it's pretty good to find what you're looking for.
John: But the real point was like, we all just know wiki is where you put stuff. Now with, we have an LLM on the front end, you just sort of say, hey, what ah what size go-no-gos do we send to our anodizer?
John: And it now tells you what Saunders does on its optimizing policies. Boom, done.
johngrimsmo: holy cow and that's a module you could add like a little search page
John: Yeah, done. ah hard The hardest part of figuring that out was the fact that most search results were trying to tell you how to create websites with with Gemini. Like, no, no, I have the site. I want to use Gemini as like the front end of the site.
johngrimsmo: Yeah.
John: And there's no haip there's no hallucination because it's only,
johngrimsmo: Cool.
johngrimsmo: You're on dinner.
John: Yeah.
johngrimsmo: Nice.
John: The Lex updates are phenomenal quality of life improvements. Again, a big tip of the hat to Alex for this. One is that um we have a page now that I go to once a week because that was like kind of one of like a weekly report.
John: And I look at it, it lists all of the purchase orders that Saunders sent out in the last week, sorts by total total size of the item placed, purchased of the item.
John: So if we bought $6,000 worth of one screw, that's going to be at the top, regardless of the overall size of the PO, et cetera, et cetera. But like, I care more about the $6,000 screws than the $22 of washers whatever. washers or whatever um And it it cites what the item is, the price we paid this week for it, and in the last three times we ordered it and the price we paid with a color coded, um like basically within 10%, we don't care.
johngrimsmo: oh
John: And then above or below that, because this actually...
johngrimsmo: Okay. Yeah.
John: It obvious use but cases to anybody who's listening and understands purchasing like simple use cases. But what it came from was we ordered some raw material that was supposed to be saw cut and the ah the vendor flame cut it So it's on them, it's their mistake, but it's a lose-lose all around because we didn't know that they flame cut it.
John: And so it shows up we're like, we can't use this. And that stinks because it's that's literally thousands of dollars that is wasted for everybody. It's lose for us, it's lose for them.
johngrimsmo: Yeah.
John: And when I looked at the purchase history, it was... 20, 25% cheaper. And tribally, I would have known, we don't save those prices fluctuate.
John: They don't, they don't, that's too good to be true. And I would have caught it.
johngrimsmo: yeah
John: um
johngrimsmo: Interesting.
John: And that's not something that I can put on. Like, it's not somebody else's fault. It's just, I want to have one day a week or one moment a week where can look at, okay, here's all the stuff we bought. Make sure there are any red flags. Do we need to adjust prices? Does something get ordered incorrectly?
johngrimsmo: hey
John: Yeah.
johngrimsmo: Well, yeah, when ah like we track our purchase orders as well, and whenever I'm ordering something that's not like every day, day to day kind of thing, I want to know when did I order it last? How much did I pay for it last? And those are like the critical things and you got to dig for it.
johngrimsmo: And you've now created a little dashboard to like, just show me.
John: All right.
John: Yep. The other one, which is super simple, but we probably should have been doing it in the past is now when you push a PO, um a lot of times there are lots of PDFs that accompany that.
John: So there could be a quote, there's usually a sales order or confirmation, and then there's usually later on a packing slip, bill of some sort, certs.
johngrimsmo: Yeah.
John: And now all of our POs in Lex, you just take any PDFs you want, drag them over the PO and uploads and attaches them to the history of that order.
johngrimsmo: Nice.
John: I think that's probably something that's ah like ISO type thing. I'm not an ISO guy, I don't know about it, but what I want to know if I can look back two months ago and say, hey, here's all the documentation that accompanied that order.
johngrimsmo: Yeah.
johngrimsmo: Yep. Yep. Find the certs for the thing. You just keep it all in one place.
John: Yeah.
johngrimsmo: That's the thing. I think we delude ourselves by thinking, oh, it's in my email. Like I can find it if I need to find it. um But to have it centralized is way easier.
John: Yep.
johngrimsmo: And like even even for us, we don't do a lot of it, but you know we send out for some water jet and we've got the Wazer water jet now. And eric Eric's like, what is the latest ah you know Norseman clip outline code? like Where do I find that? And I'm like, it's it's in GURP.
johngrimsmo: And then, ah sorry, of a DXF.
John: What do you mean outline code? Like G code?
John: oh Oh, oh.
johngrimsmo: like That's the file we send to water jet, right? Latest DXF.
John: Interesting. Yeah, that's a great, I didn't even thought about that.
johngrimsmo: And then, Yeah. So then he needs that because it's like, that's the shape of the rough cut. Like that never changes pretty much.
John: Sure.
johngrimsmo: And so he cut a bunch of Norseman clips and he's like, oh I thought you told me they were Norseman and Rask. Like it's the same clip for both. um So I just made a whole bunch of the one file thinking it would you know let you pick which Norseman or RAS clip you want to make from it. And I go, no, that's Norseman only. The RAS is a separate file um because whoever designed these files back in the day made them a quarter inch different hole spacing when they didn't have to me.
johngrimsmo: And so that that taught me the lesson of standardize your stock if you can um shape, hole size, flippability, all that stuff.
John: Wow. That's, yeah.
johngrimsmo: So no big deal, but
John: Well, no, but like, so do you rev try to rev track the DXF file name?
johngrimsmo: I put ah the date in the file name and, but these are like 2019 dates.
John: Okay. Yeah, that helps. Yeah, sure.
johngrimsmo: And you know, you look at that and you go, is that still accurate? Even though it is, but
John: Yeah, I know. i hear you. that's That's good to know. I didn't have thought about storing.
johngrimsmo: so,
John: we don't i guess we don't do that.
johngrimsmo: So that's having it stored in the location.
John: Yeah.
johngrimsmo: And if I tell everybody involved, like that's the latest one, like and everything in GERP is the latest one and that's helping.
John: yeah
John: yeah That's awesome.
johngrimsmo: Yeah.
John: ah What else?
johngrimsmo: um I'm struggling with ah our Norseman lock inserts right now. They're these thin little tiny, tiny pieces of ABL stainless steel.
John: Oh.
johngrimsmo: um We've been making for years. We machine.
John: The things you carburize, what do you call it?
johngrimsmo: ah We used to, we don't do that anymore.
John: Okay, okay. But I know that's what...
johngrimsmo: Yeah.
John: Okay.
johngrimsmo: We replaced that process with a hardened steel lock insert.
John: okay
johngrimsmo: And so we machine these things and there's some tight critical features and bores and counter bores and little tiny screws that go in them. um and engraving and a champ for 3d profile on the one side and it all has to come together and usually there's something wrong like the back chamfer is undercutting a little bit or the holes are too small or the end mill chips out or something like that and i've been fighting it for years and and they warp during heat treat so we got to like bend everyone and they're only half inch long how do you bend that just kind of overall pretty frustrating so
johngrimsmo: I'm tackling a tool wear issue right now where I've got 1 16th end mill that is, you know, when you 2d bore operation and it just goes down the outside of a bore and you know, it makes the whole, well, that wears the, at the corner radius of the end mill.
John: Sure do.
johngrimsmo: And I used a radius end mill with a 5,000 radius, like very small radius, but, and then I'm using that same tool to machine the, the screw head counter bore in this part.
John: OK, I'm with you.
johngrimsmo: And it's a very small little, very shallow counterbore. But same tool is boring down the cylinder and cutting the bigger diameter counterbore. And if the tool wears from doing too much boring, then the counterbore is chipped and too small and the head won't fit.
John: Yeah.
johngrimsmo: It won't see properly. And I never really thought about that as I was programming like same tool to do all these operations. um but now and and i'm not running parts like my team's running parts now um and i only hear about it downstream when some fit and into some don't fit and i like dig in with the microscope and like go nuts on it um so to reduce the headache scrap rate questionability honestly the white light interferometer is going to help with this a lot because i'll be able to see things like that like clear as day um
John: Sure.
John: Yeah.
John: Mm-hmm.
John: heard
johngrimsmo: So it's making me wonder about splitting the tools between one tool only does the boring and then another tool finishes the counter bore because it'll stay fresh. It's not wearing from cutting on the tips of the tool doing the bore the whole time.
John: Yes.
johngrimsmo: um Yeah.
John: Kern?
johngrimsmo: us Yes, correct.
John: Okay.
johngrimsmo: Yeah.
John: And can you, can you, instead of the bore, can you do a, is it pre-drilled?
johngrimsmo: Yes.
John: So could you not do a plunge with a center cut, like a center hole, plunging the center of the hole because pre-drilled and then do a 2D contour with it spiraling out?
johngrimsmo: I feel like I used to do that. And then I went to the bore for reasons, tool chipping reasons or chip evacuation or something. I can't remember exactly, but every, both of those solutions have tool wear issues that become issues.
John: Okay.
johngrimsmo: So so
John: ah Yeah, agree. We just went through this with one of our hobby fixture plates, which is aluminum. So toolware isn't really an issue, but taper can be and chipping the corners could be and
johngrimsmo: Yeah.
John: I'm also often find myself liking the idea of the 2D board, but we've been, we've switched some of them to that, what I said, plunging and interpolating out because I'd rather it use the full flute length, not wear those tips out.
johngrimsmo: 2D pocket.
John: And I'd rather, if it breaks, I'd rather break the whole tool because then I can use break detect to flag it.
johngrimsmo: Agreed.
johngrimsmo: But the cool thing with bore is even if the tips wear, ideally you're spring passing with the upper flutes. Like as long as you go through the hole. And I find that does work.
John: Ah, is that right?
johngrimsmo: Like we're holding good hole size.
John: Okay. That's interesting.
johngrimsmo: Yeah.
John: hadn't thought of that actually.
johngrimsmo: it It does, you know, do the thing because you're spring passing as you go deeper and deeper and deeper and deeper and deeper.
John: Okay.
johngrimsmo: But yes, the tips get killed.
John: Yeah.
John: I'm just thinking the other thing we did with Borgs we do instead of repeat pass we are going through stuff where we care a little bit more about cycle time and instead of repeat pass would do the same thing again which is kind of stupid so there's a way in bore it's not hard it's you've got to deliberate with your settings where you can have a finishing pass that is a full finishing pass at full depth like a 2d contour and it the key though is you also want it to not come out of the stinking pocket oh um okay yeah it's funny it's funny
johngrimsmo: Yeah.
johngrimsmo: yeah I broke a tool like that. yeah
johngrimsmo: Yeah.
John: hu Huh. So what's the next step on that?
johngrimsmo: Yeah. Um... i ah I changed the end mill from a certain 1 16th to a two millimeter four flute tool for hard milling that I've been using more for general stuff.
johngrimsmo: um the The new YG1 X1 EH end mills, they're working extremely well for us.
John: Yeah.
John: Yeah.
johngrimsmo: um I'm actually quite impressed with them. where you We're using them for quite a bit of hard milling and more for like some soft stainless milling too.
John: Yeah.
johngrimsmo: And they do wear, everything wears, but yeah, it's good.
John: Good. um My last two... Oh, actually I had a quick question um because I'm going through specs on machines, including with Yamazen on Brothers. they and This is what i love about our community because it's like sometimes the end users like us and you guys are way more in the know.
John: And I don't mean that as a dig against the sales guys because the truth is that like just you know you know more when you're the user. They were unclear about... Well, first off, they didn't even know about the submicron option at first.
John: They were like, oh, you want the, like, basically the more look ahead. I'm like, nope, not the more look ahead, submicron option. Then they talked about schedules.
johngrimsmo: Is that what it's officially called, Submicron?
John: I believe so.
johngrimsmo: Okay.
John: It's the fifth decimal. But then they were like, okay, you can do that, but then you have to post all of your code with five decimals.
johngrimsmo: I
johngrimsmo: i don't know.
John: And I was kind of like...
johngrimsmo: Maybe. Which is not hard. don't
John: It's not hard, but I was like, i don't know, like going back to like basic basic math.
johngrimsmo: yeah i don't know if that's fact.
John: I'm like, I don't like, I don't think to go one inch, you have to do 1.000000, but look, i'm I'm making this up.
johngrimsmo: yes
John: um You don't have any, any.
johngrimsmo: I post five decimals by default now, so I don't know.
John: Okay. Did you mod the post or is it a parameter?
johngrimsmo: I probably did, or I did it in the fusion post processor.
John: Do you know?
johngrimsmo: I don't know. I probably modded it.
John: Yeah, fair enough. Okay. Not, not a big deal.
johngrimsmo: Interesting.
John: I curious if had any comment on that. And then.
johngrimsmo: Yeah. And and like, uh, I talked about that in my Instagram post and somebody, I forget proto Hawk or whatever. Uh, he's like, I've been buying speedios for 10 years.
John: Okay.
johngrimsmo: I didn't even know this was a thing.
John: Funny.
johngrimsmo: And I'm like, Oh, well I needed it. I don't think everybody needs it. That's the thing, but it's, uh, yeah.
John: Yeah. And I don't, we won't need it on our first machine for sure. So, but I kind of want to just understand what, whatever it looks like now.
johngrimsmo: Yep.
John: um Yeah.
John: Sweet.
johngrimsmo: Cool, man.
John: what are you up to? Anything up to today?
johngrimsmo: A bit more testing on the Norseman lock inserts. I have some final tool offsets I want to finalize.
John: oh yeah
johngrimsmo: And then just, I guess machining's to the point now where I get it to where I think it's good and then I just let the team run with it and then I only hear back if it's bad.
John: yeah yeah yeah
johngrimsmo: And it works. It works.
John: yeah
johngrimsmo: That's fine.
John: um That's really, we've now on, i don't know, a month or so of four weeks of of every day um or once a week sitting down with everybody and picking a part, picking something to look through. And it's really, it's been great.
John: I'm really glad we're doing that.
johngrimsmo: That's awesome. Yeah.
John: Yeah.
johngrimsmo: Are you tracking it over time?
John: No, just short answer.
johngrimsmo: Okay.
John: No, I didn't.
johngrimsmo: It's just like live whatever's needed.
John: if And when I was preparing for this, I had sort of thought, okay, if we're struggling with stuff to come up with, then I want everybody to print out a list of the parts that they make and we'll just start crossing them off. But every time somebody's come with something to talk about, so it's like, don't overthink it.
John: Like, just start this and we'll'll we'll pivot as we go.
johngrimsmo: yeah
johngrimsmo: Sweet.
John: Yeah, agree.
johngrimsmo: Continuous improvement.
John: Yeah, exactly.
johngrimsmo: Cool, man.
John: See you next week.
johngrimsmo: Yeah, man.
