Introduction to Episode 426
00:00:01
John Saunders
Good morning or afternoon. Welcome to the Business of Machining, episode number 426. My name is John Tonders.
00:00:07
johngrimsmo
And my name is John Grimsmo.
Diverse Topics in Machining
00:00:09
John Saunders
Anything is fair game from coolant and water to new indicator stands, to speccing out machine tools, to fusion probing, to macros, to, I'll set you up here, calibrating AROA pallets.
00:00:22
johngrimsmo
Yep.
00:00:23
John Saunders
John and i talk each week about our lives running machine shop.
Calibrating AROA Pallets
00:00:28
johngrimsmo
So you want to know about calibrating your raw pellets?
00:00:30
John Saunders
I'm all ears. I want to hear about it.
00:00:31
johngrimsmo
We'll dig in real quick. So I bought the fancy Auroa branded official palette. I haven't tested it or verified or validated it yet, but I have it. And now it's mounted with a pulse stud in the machine, like ready to test whenever I'm ready. But on the other hand, the current's running fine. And it's just like, you know, will I ever get around to this? Well, I have it if I need it
00:00:51
John Saunders
This very much feels like, and I didn't even realize this this was like a theme of ours. This very much feels like a, that was a thing two weeks ago. Like I've i've moved on.
00:00:58
johngrimsmo
Yes. Yeah, I forgot all about it. And even this new palette is now in the palette changer, out of sight, out of mind. You know, there's a good chance I won't even view it for the next few weeks accidentally.
00:01:08
John Saunders
Yeah.
00:01:12
johngrimsmo
So like, I might just forget about
Calibration Challenges and Solutions
00:01:14
johngrimsmo
it. Anyway, um I'm pretty sure that my calibration that I did myself is very good. I just kind of wanted the peace of mind of having the proper kit.
00:01:22
John Saunders
Jordan.
00:01:23
johngrimsmo
um It's quality. Everything comes down quality, right? everything comes down to quality right
00:01:30
John Saunders
but So to give me some closure and maybe the audience, when we were, did we did talk about this?
00:01:34
johngrimsmo
sure
00:01:35
John Saunders
I think it was two weeks ago. And you'll probably hopefully remember better than I do of you like were good one way and like two tenths out the other, or wasn't repeating when you rotate. You were, you sounded like you wanted it better, but maybe you didn't. Maybe it was good.
00:01:49
johngrimsmo
Correct.
00:01:49
John Saunders
Maybe you just left it. Okay. Okay.
00:01:50
johngrimsmo
Yeah, I got it perfectly accurate in the in that position. But if I feel left the palette and I rotated 90 degrees to the next clamping position, which you would never do, um then it goes out.
00:01:56
John Saunders
for
00:02:01
johngrimsmo
So I'm leaning towards it being literally a rotational repeatability accuracy of the Auroa system.
00:02:01
John Saunders
Yeah.
00:02:09
johngrimsmo
I don't know what the spec is for that.
00:02:11
John Saunders
Got it.
00:02:11
johngrimsmo
um And I'm hoping this calibration palette will prove that to me. Sanity check it.
00:02:16
John Saunders
Yep.
00:02:17
johngrimsmo
which will take three minutes to put an indicator on it and, you know, reclamp it a couple times and sweep it. We'll see. So within the next couple of weeks, I'll have an answer for you just to like close the loop, but make good parts.
00:02:23
John Saunders
Yeah.
00:02:28
John Saunders
But the current is making good parts. You don't, is that because most of the current work starts from net material?
00:02:30
johngrimsmo
Yep.
00:02:34
John Saunders
So if it's off two tenths, it doesn't matter.
00:02:36
johngrimsmo
That's part of it.
00:02:37
John Saunders
Okay.
00:02:37
johngrimsmo
Yep. But on our Fjell handle, because the full five axis side to side flip flop part, centerline has to be centerline like, ideally, otherwise your pockets on each left side will be different than the pockets on the right side, because now they're away from center line.
00:02:53
johngrimsmo
If your Chuck is off center, I think.
00:02:54
John Saunders
Interesting.
00:02:57
John Saunders
Yeah, I don't disagree. i don't, I'm slower about having to think through the physicality of this.
00:03:01
johngrimsmo
Yeah.
00:03:04
John Saunders
Okay. Well, the, these are these, those gnarly pockets that you don't cover the T slot cutter that do have the sub counterbore pocket that receives the bearing pad.
00:03:15
johngrimsmo
Exactly.
00:03:15
John Saunders
That's so, okay. Okay. And those are, those are going good.
00:03:18
johngrimsmo
Yep.
00:03:18
John Saunders
Yeah. Sweet. Okay.
00:03:19
johngrimsmo
Yep. All good. So yeah.
00:03:21
John Saunders
Cool. Okay. I have a bunch of
Drilling Issues and Solutions
00:03:25
John Saunders
stuff.
00:03:25
johngrimsmo
Good lay on me.
00:03:26
John Saunders
let's bang through it. First off, um, to give some closure on, I think I brought up last week, drilling, um, drilling and seal and dual life.
00:03:34
johngrimsmo
Hmm.
00:03:35
John Saunders
We, um, I feel proud. don't know what the objective is. Like it's fun to develop a regiment or a, criteria through which you're going to test it. So like number one thing is just like, just isolate it. So, um, quickly recap, we have a big, big drill called 12 millimeter that just drills blind holes in fixture plates.
00:03:58
John Saunders
And those, um, those holes are drilled after the material is faced. So it's drilling into freshly machined material. ah period. And those drills last great. The same manufacturer drill, slightly smaller diameter, we have significantly inferior to a life because that through hole is poking through the bottom of the material, which still has male mill scale.
00:04:21
John Saunders
I can't prove that the mill scale the issue, but it makes sense both because of what I just described, but also mill drilling through mill scale is just different. it can be quite hard or not even so much that it's hard. It can be inconsistent, sporadic,
00:04:35
John Saunders
kind of like, you know, punching a, yeah, it just is.
00:04:35
johngrimsmo
yeah
00:04:39
John Saunders
So
00:04:39
johngrimsmo
well in this case you're milling out of mill scale not into mill scale yeah which is an interesting scenario i guess
00:04:40
John Saunders
oh
00:04:44
John Saunders
you're drilling, poking out through the bottom of it. Yes. Yeah.
00:04:50
John Saunders
So first thing we're doing is actually happening coincidentally right now is we're taking that second drill that we've had tool like issues with and we're not drilling through it. We're just keeping the drill 5,000, keeping it blind, leaving it 5,000 high. And then we're just coming back through with an end mill or something else.
00:05:05
John Saunders
Obviously it's quite slow, but we're going to interpolate through the rest of that hole. Cause I don't care about the end mill. And then we'll see, does this solve the problem? Like, so number one, if our thesis is true, it should be, we shouldn't have to do that many fixture plates to realize, great. Now we understand what the problem is.
00:05:20
johngrimsmo
ye
00:05:20
John Saunders
over the, um, for us here in U S we, did you guys have yesterday off Labor Day?
00:05:24
johngrimsmo
Yeah.
00:05:24
John Saunders
Does that have Oh, okay.
00:05:25
johngrimsmo
Yeah.
00:05:25
John Saunders
So yeah, great. We all a holiday. Um, I had had a note of it's kind of one of those inverse Grimm's where it takes one third the time and instead of three times as long.
00:05:36
johngrimsmo
yeah Okay.
00:05:36
John Saunders
Um, um, I was like, okay, John, what is it going to take to write a custom drill cycle? Like I want to have my own drill, control over like a G whatever, like deep drilling, peck drilling, reaming, but like one on my own.
00:05:47
johngrimsmo
Okay.
00:05:51
John Saunders
Is that something I write in Fusion? is it something i write in the post? Is it something that I have to write on the Okuma machine control? Like i was just like, well, look, never been a better time. I'm sure there's websites, resources, blogs, chat, GBT examples.
00:06:04
John Saunders
And so I just start, I pour myself the cup of coffee, I sit down and you, sometimes you got to remind yourself not to be too
Innovations in Drill Cycles
00:06:10
John Saunders
smart. It's just like, just ask In this case, i don't think I even, um I don't think I even, and didn't even get into ChatGPT because I just went into Fusion.
00:06:19
John Saunders
And um I certainly hope you're guilty of this because it would make me feel better in a weird way.
00:06:25
johngrimsmo
do yeah
00:06:25
John Saunders
But like, you know, we've used this software so long that we're so comfortable that sometimes you just forget to be, to let yourself be a novice and and relax. And so I went to the,
00:06:33
johngrimsmo
look around and
00:06:34
John Saunders
Yeah. So drill, look through the geometry options, the cycle options, drilling cycle. When you hover over it it's actually not the best UI for my opinion for Autodesk. You get an explanation of some of cycle types. You don't see them all, but it says, if you click the i on the bottom left, it takes you to an Autodesk website that explains all the cycles.
00:06:54
John Saunders
What I had been planning to do was find one of these cycles and see if I could kind of interrogate how it's coded or how it handles stuff and then kind of use that as a starting point. Well, There's already a cycle that does exactly what I want.
00:07:07
johngrimsmo
Nice.
00:07:09
John Saunders
There's a cycle called breakthrough that allows you to control a dimensioned height from the bottom of your drill, program drill. And at that height, it will then change your feeds and speeds to whatever you want, higher or lower on either one.
00:07:21
johngrimsmo
Interesting. Okay.
00:07:24
John Saunders
Which is great. That means we could take our drill and we could run it through all the good material at our normal feed rate. And then if we wanted to assume slow down on both service footage and feed for tooth for that last 50 thou, you can do it.
00:07:34
johngrimsmo
Mm-hmm.
00:07:37
John Saunders
We don't have to do any, no hand coding, no customization, et cetera.
00:07:42
johngrimsmo
Yeah, that sounds great.
00:07:43
John Saunders
Right? i was like, that's a win.
00:07:45
johngrimsmo
Yeah, and very um ah consistent and provable you know if you get
00:07:50
John Saunders
Yeah. Yes. um Okay. My next item.
Probing Strategies in Machining
00:07:56
John Saunders
i When we put raw material on the, ah we call it up zero.
00:08:02
John Saunders
We will usually cut either machine two features or drill two holes. I don't know. Well, if we drill them, we know where they are. Bear with me here. Here's my example. I want to use probing to see if a part has moved because ah just want to know if we're doing a precarious work holding or something this sort.
00:08:21
John Saunders
And so bingo.
00:08:22
johngrimsmo
Like a before and after move. Yeah. Okay.
00:08:25
John Saunders
And now the thing is that the part isn't necessarily in the perfect spot to begin with. So for I guess for the sake of this example, let's say you're taking a um piece of paper size raw material and let's say there's a hole in that bottom left corner and then hole is always within the same 20 thou center line.
00:08:47
John Saunders
Like it's about within 20 thou every time, but it's not like it's within a thousandth of an inch.
00:08:49
johngrimsmo
Yeah.
00:08:51
John Saunders
Like it's, it moves a little bit.
00:08:52
johngrimsmo
got.
00:08:53
John Saunders
So you want to come in and I want to have Fusion probe the center of that bore at the very beginning, store it, And then at the end, I wanted to reprove that bore and tell me if it moved.
00:09:00
johngrimsmo
Yeah.
00:09:04
John Saunders
This is was on my to-do list this weekend and I didn't get to it. So I'm taking advantage of our phone call to ask you if you've thought of this.
00:09:10
johngrimsmo
Mm-hmm.
00:09:11
John Saunders
I know it would be easy to do if you just want to probe a known feature and sort of say, hey, does that match the CAD model? um But this is, I think, different. Does that make sense?
00:09:22
johngrimsmo
Do you want to know how I would tackle that?
00:09:27
John Saunders
Yeah.
00:09:28
johngrimsmo
So at least with hide nine cycles and I mean all cycles. Anyway, if say the hole is at minus one minus one inch, right?
00:09:40
johngrimsmo
And you know that there's a way to type your probing cycle to be like, here's your position. And then it puts the difference, the the positional variation into other macro variables.
00:09:52
johngrimsmo
So whatever it is, 912 or whatever, um will tell you two tenths why five tenths X.
00:09:54
John Saunders
OK. Yeah.
00:10:01
johngrimsmo
um And that's the answer you're looking for, is it not?
00:10:06
John Saunders
Actually, yes. Now that we talked through this, I just realized this is on a Akuma, which is not, doesn't use geity forward but let's say it does. so In Fusion, I can probe a feature, but instead of updating G54, which is my main state work offset, I can just have it update G59 on the first.
00:10:24
johngrimsmo
I see the difference.
00:10:25
John Saunders
So you can update on the first one, which means Fusion's not going to care where... that bore is within 50 thou because it's just you need to get the probe into the tip or probe tip into the hole and then it'll be able to update g fifty nine And G59 is only there for the sake of documenting this change.
00:10:40
johngrimsmo
Oh.
00:10:43
John Saunders
Then what I can do at the end of the program is go in and use g fifty nine to do a validation point of figure what it's called infusion where you can say, hey, does my part match spec?
00:10:43
johngrimsmo
Sure.
00:10:50
johngrimsmo
Yep.
00:10:56
johngrimsmo
he
00:10:57
John Saunders
compare what it probes right now against what I had saved as a G59. That way I'm not involving my main GT4 work offset. This should work fine.
00:11:05
johngrimsmo
Yeah, and and you're not hand coding anything, which is totally how I would do it.
00:11:05
John Saunders
Perfect.
00:11:09
John Saunders
Yeah, no, no, it's exactly great.
00:11:10
johngrimsmo
Perfect.
00:11:10
John Saunders
um Thank you. I'm
00:11:13
johngrimsmo
Yeah.
00:11:15
John Saunders
making a note, for...
00:11:17
johngrimsmo
Is this a sanity check or is it kind of sketchy work holding curiosity, want to know sort of thing?
00:11:23
John Saunders
um It is both. No, it's we do an op zero where we we do barely hold on to the material to get some reference datums added. And we want to do a little bit more and i think we'll be okay with that.
00:11:37
John Saunders
and I really wanted to add indicators on the part, but we use enough coolant where we, and I can't turn the coolant off because of the thing like tapping and drilling. It's just, it's not worth it.
00:11:46
johngrimsmo
yeah
00:11:47
John Saunders
I was like, can I put a coolant in like a Ziploc bag? Or can I put an indicator in a Ziploc bag? But I realized, what are you doing, John? Just probe it. You'll be fine.
00:11:56
johngrimsmo
Yeah.
00:11:58
John Saunders
That'll work. Okay.
00:11:59
johngrimsmo
Assuming the work piece doesn't dimensionally warp or something, i don't know what you're making, but yeah.
00:12:05
John Saunders
Yeah, that won't. That'll be okay there. yeah oh Well, dude, we're banging through it. um
00:12:12
johngrimsmo
Good, yeah.
00:12:15
John Saunders
My other question is gonna be about your brothers, but um I should defer to what...
00:12:18
johngrimsmo
I only have one brother, both both in real life and machine.
00:12:23
John Saunders
So you have two brothers, Eric and How's S500 doing?
00:12:24
johngrimsmo
um do have two brothers, dang it. Yes, exactly. What is your question specifically? Eric's doing fine.
00:12:33
John Saunders
how's yours how how's s five hundred doing
00:12:35
johngrimsmo
S500 Brother is good. Our main guy that runs it is just coming back from a canoeing trip, so he's off today. um But Angelo's running it, and he was actually saying, he's like, look, I know how to run this, but I still, I want more process sheets so that I can come up here and be confident that this program is the latest one for this part, because I have to, like...
00:12:52
John Saunders
no Yeah.
00:12:58
johngrimsmo
I feel like I'm guessing a little bit more than I should. i want this to be more outlined so that any of us can come up and do the work.
00:13:05
John Saunders
Yeah, I love it
00:13:05
johngrimsmo
And that was very valid. And it that's a perfect example of obviously a capable person switching shoes with another capable person and having enough clarity to pull it off.
00:13:13
John Saunders
Mm-hmm.
00:13:20
John Saunders
Yes.
Machine Build Quality and Performance
00:13:21
John Saunders
Kind of reminds me like those TV shows and I don't know if how valuable it is versus just hokey TV show content where it's like, employee does the boss's job and boss does the employee's job, but just kind of role switching to help you, um, in a weird way.
00:13:32
johngrimsmo
Yeah.
00:13:34
John Saunders
That's if what we've been doing with those cam sit downs. It wasn't, well, there was the intent, but i mean, the intent was like, Hey, let's look through parts. Let's interrogate best practices.
00:13:41
johngrimsmo
Sure.
00:13:42
John Saunders
Let's share what we've learned. but it also involves a little bit of, um, seeing each other's stuff.
00:13:48
johngrimsmo
Yeah. a little bit back and forth. But mechanically, the Speedio is a total rock star.
00:13:54
John Saunders
Yeah.
00:13:54
johngrimsmo
I really, really like the machine.
00:13:57
John Saunders
That's good to hear. You feel like the build quality is great.
00:13:59
johngrimsmo
I think it's fantastic. It's...
00:14:02
John Saunders
I mean, you have some nice machines.
00:14:02
johngrimsmo
different like one nitpicky thing i heard it today when it's doing a very small very small engraving you know the little ball mill goes down and then it lifts up in rapid but not far 20 thou or something lifts up goes down feeds down lifts up and on the lift up it kind of makes this like chunk noise
00:14:10
John Saunders
Mm-hmm.
00:14:14
John Saunders
Mm-hmm. Mm-hmm.
00:14:23
John Saunders
Hmm.
00:14:24
johngrimsmo
And it's always done that, even from new. And I don't know if that's a speedio thing or just a My Machine thing. There's no backlash in Z, but it seems like it sounds like there is backlash.
00:14:31
John Saunders
Yeah.
00:14:33
johngrimsmo
Or maybe it's just it's so fast that when it has to move 20,000, it just goes chunk.
00:14:36
John Saunders
Yeah, right, right. Hmm.
00:14:39
johngrimsmo
um That's my only kind of minor complaint, but it makes no difference. it just I hear it.
00:14:44
John Saunders
Okay. yeah Not like tool life or it's not walking.
00:14:46
johngrimsmo
Yeah.
00:14:47
John Saunders
Do you have a bolted to the floor?
00:14:48
johngrimsmo
No. No.
00:14:49
John Saunders
and Interesting.
00:14:50
johngrimsmo
it's It's on four feet, and they're maybe four-inch diameter cast-iron pucks, and they have sandpaper on the bottom of them.
00:14:58
John Saunders
Like you put sandpaper or y'all or
00:14:59
johngrimsmo
No, they came like that.
00:15:01
John Saunders
was funny.
00:15:02
johngrimsmo
And our floors are like beautiful epoxy, and I'm like, no, I hope I don't have to move this machine.
00:15:02
John Saunders
there'
00:15:08
johngrimsmo
um
00:15:08
John Saunders
Well, the good news is you'll know if it moves because you have a little sanded.
00:15:11
johngrimsmo
Exactly.
00:15:11
John Saunders
ah
00:15:12
johngrimsmo
Yeah.
00:15:13
John Saunders
Do you have, and you have you do have both a table probe and a spindle probe?
00:15:17
johngrimsmo
Yeah, I have a table laser and a spindle probe.
00:15:19
John Saunders
Yes.
00:15:20
johngrimsmo
Yeah, for our grinding wheel.
00:15:20
John Saunders
And did you do table laser spindle probe and are they both bloom?
00:15:26
johngrimsmo
Yes.
00:15:27
John Saunders
Okay. Couldn't remember. There was something about the Renishal bloom mix that some people do.
00:15:31
johngrimsmo
Yeah, some people use, what is it, Renishaw macros on Bloom probes or the other way around or something.
00:15:36
John Saunders
Okay.
00:15:36
johngrimsmo
um Yeah, but Renishaw stuff's great too.
00:15:37
John Saunders
Maybe I swear.
00:15:40
John Saunders
And then do you have, do you have three spin of coin?
00:15:45
johngrimsmo
Do have through spindle. I like that. It's like I was talking with another friend in Canada who's looking to buy an S700 and he shared his build spec with me and he's like, what should I get?
00:15:55
John Saunders
Yeah.
00:15:55
johngrimsmo
what i it It depends on how much you want to spend on it and really like what you're going to use. um And, you know, some people are never going to use through spindle coolant. I don't use it much, but I'm sure glad I have it.
00:16:08
John Saunders
Is it a separate physical large unit?
00:16:11
johngrimsmo
It's no, it's, um, it goes on the coolant tank, but it is a separate pump.
00:16:16
John Saunders
No, that I'm okay with.
00:16:17
johngrimsmo
Yeah.
00:16:17
John Saunders
So um I'll take it to the extreme to help help share my logic.
00:16:17
johngrimsmo
Yeah.
00:16:25
John Saunders
If we were gonna buy 10, we're not. but If we were gonna buy 10 of these,
00:16:27
johngrimsmo
Yeah.
00:16:29
John Saunders
um i I want to make sure it's the right decision. Cause here's the thing, i love through spindle coolant. We had it with our first VM3. We use it all the time on on drills, on face mills, on cleaning.
00:16:39
John Saunders
um I love through spindle coolant.
00:16:40
johngrimsmo
yeah
00:16:41
John Saunders
On the Haases, they, I think do a great job. it's It's a feature cost, it's a pump that fits on your tank. So it doesn't take up any more real estate. It doesn't involve additional maintenance, things that can be e-stop, things that have like whatever.
00:16:53
John Saunders
the Okuma's, they're quite good, but the Okuma through spindle coolant is like the size of an s three hundred machine. um it's it's
00:17:01
johngrimsmo
Well, it's like on the current, like it's an external coolant system.
00:17:05
John Saunders
very large yes um and you know these are usually five figure systems like they're they're not inexpensive which i wouldn't shortchange the right build spec just for money but when it's money and a bunch of real estate because here's the thing most of the time we're drilling it's two to three times d and there are benefits from through spindle but um
00:17:06
johngrimsmo
Yeah. Yeah.
00:17:19
johngrimsmo
Sure.
00:17:23
johngrimsmo
Yeah.
00:17:26
John Saunders
part of me wanted to think about like, Hey, if you're gonna buy 10 of these, do you really want 10? Um, do you need it? Like, and then it's the brothers are so fast.
00:17:32
johngrimsmo
yeah
00:17:34
John Saunders
I found some YouTube videos to confirm there it basically is no lag. Like if it needs to be a cool, it's just on, it doesn't seem to slow down tool change time.
00:17:44
johngrimsmo
no um although there is a kind of an i don't know we have this problem and some other people have had it too where the um
00:17:44
John Saunders
Um, which is actually insanely impressive.
00:17:52
johngrimsmo
The pump isn't primed when you need it to be primed or something. Like if it sits for the weekend, it'll alarm out because it, it whatever, hasn't seen pressure in two seconds or something like that. um
00:18:02
John Saunders
Interesting. interesting
00:18:03
johngrimsmo
So in my warmup routine, I have through spindle coolant for 10 seconds first, the very first operation in the warmup. So that if it's going to air out, you're there. You're literally, you just hit go.
00:18:14
John Saunders
That's a great, that's really smart.
00:18:16
johngrimsmo
And then... If you see the through spindle going, you can walk away and let it finish. Otherwise it'll yell at you within a few seconds. Um, and then usually within the day, it's fine. Like,
00:18:26
John Saunders
How do you remedy that alarm prime issue?
00:18:29
johngrimsmo
I think you just do it again a couple of times.
00:18:31
John Saunders
Ah, okay. It's not like some wrenches and maintenance tasks.
00:18:32
johngrimsmo
Yeah. No, no. You literally just call through spindle again and, uh, hope it works this time.
00:18:37
John Saunders
Okay. Okay.
00:18:39
johngrimsmo
And I don't know exactly why, what's up with that, but whatever.
00:18:43
John Saunders
Yeah. And then what was the, um remind me the whole higher high accuracy thing.
00:18:48
johngrimsmo
and do
00:18:50
John Saunders
And do you know if that's changed on the like new X2D00 controls?
00:18:55
johngrimsmo
I don't.
00:18:56
John Saunders
okay
00:18:57
johngrimsmo
I know the D00 is generally more accurate, it has more pulses per rev or whatever, like a lot more. ah I don't know if the high accuracy mode affects that at all.
00:19:05
John Saunders
OK.
00:19:08
johngrimsmo
But basically what they do is they have this little tiny chip, looks like a RAM stick,
00:19:14
John Saunders
Mm-hmm.
00:19:14
johngrimsmo
um that adds onto the machine, which gives you, I think, two options. And you pay for the stick with one option or two options, whatever. And that option could be ah high-speed look-ahead.
00:19:27
johngrimsmo
It could be high-accuracy mode, which gives you a fifth decimal inch, or I guess a fourth decimal metric, whatever that is. um i That made a huge difference for what I'm doing.
00:19:40
John Saunders
Fifth decimal, because you still can adjust in tenths. You just couldn't adjust in quote unquote millionths.
00:19:45
johngrimsmo
Correct. So yeah, four decimal is one 10th, five decimal is 10 millionths.
00:19:47
John Saunders
Okay. Yeah.
00:19:50
johngrimsmo
And for the grinding accuracy that we were doing, I absolutely saw steps in the finish at one 10th increments, but at 10 millionth increments, it's gone.
00:19:57
John Saunders
Okay. I don't think I need that, but it also really irks me to think that like,
00:20:01
johngrimsmo
Yeah. Yeah.
00:20:04
John Saunders
I don't know. I was trying to, I'll do some more research, but I was like, I wonder if they have now included it. So it's at least just a software unlock versus installing a physical chip or card.
00:20:11
johngrimsmo
Yeah, that's good question. see I have to install the chip and reboot the machine and do something weird. I forget. You have to choose the option you want.
00:20:21
John Saunders
Yeah. Yeah.
00:20:23
johngrimsmo
um But I think if you know the menus, you can choose a different option. Like I could turn off high speed or whatever, high accuracy and
High-Accuracy Mode in Hard Milling
00:20:32
johngrimsmo
do the other one.
00:20:34
John Saunders
i ah look ahead I don't need um and don't need the i don't think i need either one of them.
00:20:35
johngrimsmo
Yeah, yeah.
00:20:42
John Saunders
I will say like it has been interesting in the Okuma horizontal doing hard milling with high end tools and you're like, man, there's like a value that's just like, you know, I don't believe that 10 millionths is a reliable number that a machine can like control.
00:20:56
John Saunders
But I also think it's more accurate than a tenth just in terms of like how you want it to
00:21:01
johngrimsmo
Yep.
00:21:01
John Saunders
handle something and sometimes you do you're like oh man i can't comp the tool and i can't fusion and po like just i don't want to limited or at least i want to understand what the limitation would be
00:21:07
johngrimsmo
Literally.
00:21:10
johngrimsmo
Yep. And I remember talking with Greg about this. so I forget the exact numbers, but since mine is the C00 control, the new newer ones are the D00.
00:21:18
John Saunders
mm-hmm sorry okay
00:21:21
johngrimsmo
My stepper motors have, servo motors, have so many pulses per inch or per rotation or whatever, whereas the D00 ones have like 100 times more. ah hundred times more
00:21:33
John Saunders
Oh, wow.
00:21:33
johngrimsmo
like like millions of pulses per inch.
00:21:33
John Saunders
OK.
00:21:36
johngrimsmo
So when you're resolving down past, I think I was asking him the difference between inch mode and metric mode, because I could theoretically get more accuracy if I go to metric mode and go from 10 millionths down to essentially four millionths in metric.
00:21:43
John Saunders
Yeah.
00:21:51
John Saunders
Right.
00:21:52
johngrimsmo
But he's like, your machine has like four four individual pulses between the 10 millionth tick, but like no resolution.
00:22:00
John Saunders
OK.
00:22:02
John Saunders
Yeah.
00:22:03
johngrimsmo
Whereas the D zero zero ones have like a, you know, a thousand pulses still between that range, something like that.
00:22:10
John Saunders
Okay.
00:22:10
johngrimsmo
Um, anyway, that's that. And then, um, yeah, other options, there's all the tool changer options, like 21, 28, 15, whatever, 28.
00:22:18
John Saunders
twenty s Yeah, 20s. Yeah.
00:22:20
johngrimsmo
Yeah. Mine's 21.
00:22:20
John Saunders
Yeah.
00:22:21
johngrimsmo
Cause 28 didn't exist at that time. Um, thankfully we currently only use it with like four tools at a time, just doing repeat hard milling.
00:22:28
John Saunders
ah That's really nice, actually. Yeah, Riri.
00:22:30
johngrimsmo
So it's kind of great. Um, but I know a lot of guys, especially buying their first video, it's like you and me 10 years ago, working going to buy one machine. That's going to do everything.
00:22:40
John Saunders
Yeah, yeah, yeah. Well, mean, this weekend, I couldn't not click on the animated preview of how the 100 tools, they have a 100 tool thing works.
00:22:47
johngrimsmo
haven't seen that yet.
00:22:48
John Saunders
So it's the same, um it's the same or similar front umbrella, which is, it's, it's I would say it's ingenious.
00:22:53
johngrimsmo
Yeah.
00:22:55
John Saunders
I give him some credit.
00:22:55
johngrimsmo
Totally. I mean, I saw it like three months ago whenever it was passed around, but if there's new, I haven't seen it yet.
00:23:00
John Saunders
Yeah. Yeah, there's a YouTube, or Yamas, I think has a YouTube animation, but it has,
00:23:01
johngrimsmo
Yeah. And
00:23:06
John Saunders
Um, it has a side kind of like a Haas has a side mount tool changer on the left. So it has a, it has a big ring on the left and the right that each hold, I believe 36 tools.
00:23:10
johngrimsmo
Yeah.
00:23:15
John Saunders
And then there's just like a punch piston arm, like a, like an arcade game where it just punches out. And what it does is it always leaves an open pocket in the main umbrella, And then the arm can go in, it pulls a tool out of your main one, and then it in in that goes into the empty one in the sidearm, and then it rotates the sidearm one index to the tool you would want to It pushes the sidearm tool out and into the main front one.
00:23:41
johngrimsmo
Yeah.
00:23:42
John Saunders
So it would be, I'm assuming that you can automate it because it would probably take, i don't know, it would probably take the machine five to 10 minutes to swap all them out itself, but who cares if it can do it, you if it knows how to do it.
00:23:52
johngrimsmo
Totally. And I wasn't sure if that was an as needed basis or if it like you need to run 28 tools in your program, but it can load whatever 28 tools of your 100 you want, or if it can like call it mid cycle.
00:24:06
johngrimsmo
I don't know.
00:24:06
John Saunders
I can't answer that. I would be shocked if you weren't able to use 100 tools with like program apart that had all 100 tools used, walk away, come back, and it's done.
00:24:10
johngrimsmo
Right.
00:24:15
John Saunders
Like it be so might be slow, pretty sure.
00:24:15
johngrimsmo
Yeah, yeah. Yeah, interesting.
00:24:21
johngrimsmo
so you're gonna get that one?
00:24:23
John Saunders
but No, no, no.
00:24:24
johngrimsmo
No. It's pretty cool though.
00:24:27
John Saunders
I give him a lot of credit, yeah.
00:24:29
johngrimsmo
Yeah, oh sure, it's kind of brilliant.
00:24:32
John Saunders
In the footprint of it, yeah.
00:24:33
johngrimsmo
it it It proves their resolve for the S platform, like S300, 500, 700,000, whatever, because they're like, no, no, the machine's fine, but we're just going to add more tools.
00:24:40
John Saunders
Yeah.
00:24:46
John Saunders
Right. Yeah. I think i've asked this before. i don't even know why asking really, but like you could teach me the control or you could teach.
00:24:54
johngrimsmo
it's It's very fanicky.
00:24:57
John Saunders
but that doesn't help right now. That doesn't make me feel better.
00:24:58
johngrimsmo
Yeah, I guess you don't have a lot of fanic stuff.
00:25:01
John Saunders
Willie's FANUC. I've never used it. um Well, FANUC to me scares me. It's like sub menus, non-intuitive, like...
00:25:08
johngrimsmo
it's more intuitive than that um because it's very it's fine like with any machine you just you take you take a while looking for the thing you're looking for but they're yeah
00:25:19
John Saunders
But if I said, okay. Now not worried about because I'll learn it. There's enough people out there, but it so it sounds like it's not like Heidenheim where you're like, welcome welcome to my, good.
00:25:29
johngrimsmo
um
00:25:33
John Saunders
Yours is an S500, XD1, whatever.
00:25:35
johngrimsmo
Yes.
00:25:38
John Saunders
Knowing what you know now, I care about the size. If we do this at our shop, I do care about the size. I also brought that limited. So it seems, I don't know that I want to spend the time to try to make sure if I were works when it's just like the 700 is just a no brainer.
00:25:53
John Saunders
Does that make sense?
00:25:54
johngrimsmo
Yeah, a lot of people just default to the 700.
00:25:54
John Saunders
like
00:25:57
John Saunders
Yeah.
00:25:57
johngrimsmo
um I know the knife makers especially justify it's like I can fit four pallets on it um and do all of the works.
00:26:03
John Saunders
Okay.
00:26:05
johngrimsmo
I think 700's like VF2 sized? VF3. I don't
00:26:10
John Saunders
Actually don't even, I have in front me here.
00:26:13
johngrimsmo
know. 500's not big. It's 20 inches and in X.
00:26:13
John Saunders
but Yeah, it's pretty tight, right?
00:26:16
johngrimsmo
Yeah, but I'm very happy with it for what I'm doing.
00:26:19
John Saunders
Okay. biggest, although
00:26:19
johngrimsmo
um It depends on what you want it for.
00:26:23
John Saunders
thought there was thousand, but is that like the W or anything?
00:26:26
johngrimsmo
yeah. Okay.
00:26:27
John Saunders
and the seven hundred is twenty seven point six inches and that's the biggest although i thought there was a thousand but is that like the double
00:26:33
johngrimsmo
There's a thousand. Yeah.
00:26:34
John Saunders
like w or
00:26:34
johngrimsmo
That's like a 40 by 20 basically.
00:26:37
John Saunders
It's different machine.
00:26:38
johngrimsmo
Maybe.
00:26:39
John Saunders
It's not even the S series, I think. Okay.
00:26:40
johngrimsmo
Yeah. i don't know.
00:26:42
John Saunders
And then I was like, oh my gosh, the S 300. They're actually one of the parts we're thinking about. I'm like like, it would work there, but it thent just feels so strange to be buying.
00:26:46
johngrimsmo
Yeah.
00:26:50
johngrimsmo
And the price difference is like four grand between each size machine.
00:26:53
John Saunders
Yeah. Yeah.
00:26:53
johngrimsmo
It's like nothing, but I know Dennis has a bunch of S300s and they're like little phone booths.
00:26:53
John Saunders
Yeah. Right.
00:26:58
John Saunders
Yeah.
00:26:58
johngrimsmo
they're
00:26:58
John Saunders
Right.
00:26:59
johngrimsmo
It's kind of tempting to like want a bunch of those because yeah the footprint is just amazing on these machines.
00:27:06
John Saunders
Yeah, Wayne, so the whole part of this, it goes hat in hand with you are robots. So I don't, i actually don't necessarily need or want or can justify a larger footprint because you actually need to think about the access in and out that way.
00:27:12
johngrimsmo
Yeah.
00:27:20
johngrimsmo
And if you're thinking about that, do you need a huge table to fit a total ton of parts if you're going to auto loading one piece flow?
00:27:25
John Saunders
It's one piece flow.
00:27:27
johngrimsmo
So like literally 300, a use 300 300 might
00:27:28
John Saunders
Yep, you don't.
00:27:33
johngrimsmo
six
00:27:34
John Saunders
Yeah, right. but Yeah, that's where, um I have an open mind and I saw the Yamazin tournament a pretty crazy promo. i actually think right now I'm telling myself, first off, we're not pulling the trigger today anyways, like today, if you will.
00:27:47
johngrimsmo
sure
00:27:48
John Saunders
But I... i Could see myself getting getting a good deal with like legit used equipment or just buy new because it's something i it's not that I need the latest and greatest.
00:28:00
John Saunders
I recognize that that's not always the best way to go here, but some of the improvements in the controls do look pretty legit on the D-Zero.
00:28:06
johngrimsmo
yeah
00:28:07
John Saunders
And if we're going to do this and we end up buying three or four, I do want them all to match.
00:28:12
johngrimsmo
That's fair. Yeah. Very valid.
00:28:15
John Saunders
Yeah. And the art and like to be blunt too, if i if I believe my own projections, which the thing that are true about projections is they're always wrong. But like, if I believe in them, the overall ballpark of the investment matters, but like saving three grand or seven grand or even 11 grand over a a reasonable lifetime is not that material.
00:28:22
johngrimsmo
Yeah. good
00:28:35
johngrimsmo
Yeah.
00:28:35
John Saunders
um but so I still take it seriously, but yeah.
00:28:37
johngrimsmo
And then there's also the U500, which, you know, if I needed it to buy a machine tomorrow would probably be near the top of my list. The five axis S 500. Sure.
00:28:47
John Saunders
Yeah, i I need to learn more about that. Some very polarizing outcomes in and in the instant machinist world there.
00:28:53
johngrimsmo
Yeah.
00:28:55
johngrimsmo
Yeah. don't know.
00:28:57
John Saunders
I'll leave it at that.
00:28:58
johngrimsmo
Yep. And it depends on what you need it for.
00:28:59
John Saunders
Also, though, totally, um ah I think they have a new version though. I didn't follow that. Some there was some chat, a newer version of it, which I think also changed the Z axis or I don't know if that's a zero or a 90, or is that a B?
00:29:14
johngrimsmo
Okay. know. don't
00:29:17
John Saunders
That's a B. Ooh, it's a B machine, right?
00:29:19
johngrimsmo
i don't know. I feel like it's a name machine.
00:29:21
John Saunders
X, Y. No, it's left to right. but trying The pivot X, Y, it's across it was an A.
00:29:25
johngrimsmo
Yeah.
00:29:30
John Saunders
it's an A.
00:29:30
johngrimsmo
Okay.
00:29:31
John Saunders
Yours is a B. Yeah, yeah.
00:29:32
johngrimsmo
Yes. The current, yeah.
Unexpected Results from Argon Purge Test
00:29:40
John Saunders
What's going on in your world?
00:29:41
johngrimsmo
um last week we talked about the argon purge in heat read right so i have i have a result i have two results i do not understand them but they're very interesting this just happened a couple hours ago um so our guy larry did ah round of heat treat he said regular blade regular bag
00:29:46
John Saunders
Yes. Yes.
00:29:50
John Saunders
Okay.
00:29:53
John Saunders
Okay.
00:29:55
John Saunders
Okay.
00:30:04
johngrimsmo
with a piece of paper in it nothing else different just a piece of paper and he also did a bunch of regular blades to his normal way so he did one blade with just a piece of paper inside he said that bag all the other ones sucked flat because they consume the oxygen that's inside like they normally do the one with the paper blew up expanded
00:30:05
John Saunders
Okay.
00:30:11
John Saunders
Okay.
00:30:25
johngrimsmo
um like inflated, I guess is the best word for it, to the point where when he pulled it out, it was stuck between the ceramic rods.
00:30:33
John Saunders
Oh my gosh.
00:30:34
johngrimsmo
I'm like, dude, all you do is put paper in there. He's like, I know. And then he did another blade with about eight seconds of argon purge inside, and then he folded it while it was still pointing up in the sky, and then sealed it really good, triple folded it, and also put a piece of paper in there.
00:30:44
John Saunders
of
00:30:51
johngrimsmo
And he said, that one... um that one shrunk down and crinkled in super weird ways and folded over itself and looks like shriveled raisin. And I'm like, this is totally backwards from anything i thought was going to happen right now.
00:31:04
John Saunders
Yeah, right?
00:31:08
John Saunders
This seems really odd.
00:31:09
johngrimsmo
so I have no idea what's going to happen. So anyway, his suggestion was tomorrow to the same thing with no paper and just see if that makes a difference.
00:31:16
John Saunders
Yeah, all right,
00:31:17
johngrimsmo
Maybe it is the paper. It's just a piece of printer paper, probably less than one square inch
00:31:21
John Saunders
right. Oh, you didn't crumple up a whole sheet.
00:31:23
johngrimsmo
No, no.
00:31:24
John Saunders
was just, yeah, little sliver.
00:31:25
johngrimsmo
yeah Probably half a square inch, if I had to say.
00:31:26
John Saunders
Okay.
00:31:28
johngrimsmo
um so yeah
00:31:31
John Saunders
Interesting.
00:31:32
johngrimsmo
It's a weird result.
00:31:34
John Saunders
The paper ones, you had two paper ones, one expanded, one still shrunk. Did the paper was also gone though? Because,
00:31:41
johngrimsmo
It was black charred. um but There was still a bit of a square there, but a lot of dust as well.
00:31:43
John Saunders
yeah, like nothing.
00:31:49
John Saunders
Gosh, that's...
00:31:49
johngrimsmo
So it's kind of interesting. I don't.
00:31:51
John Saunders
i
00:31:52
johngrimsmo
So our first thought is there like, I look at the tank. Is that really Argon? I read the label like very slowly. Yes, Argon. um And then like Larry's worked in industry for forever. He's in his 50s.
00:32:07
johngrimsmo
And he's like, we've had bad batches before at our previous job. Like maybe it's a bad mix. Maybe it's not. I don't know. you know, everything's on the table at this point.
00:32:15
John Saunders
gosh
00:32:17
johngrimsmo
I don't know.
00:32:18
John Saunders
That seems crazy, but no, you're right.
00:32:20
johngrimsmo
I agree. Yeah.
00:32:21
John Saunders
i mean mean, gases get mixed up or whatever.
00:32:24
johngrimsmo
Yeah. yeah And I'm like, how do you tell if it's argon? Maybe you could, because it's an inert gas, it should put out a flame, right? um i tried that, but it blew it away.
00:32:34
John Saunders
right
00:32:35
johngrimsmo
so maybe there's a way to do it. I don't know. um I'm sure there's a way with like a bowl and a little tea candle inside and you fill the outside bowl with... argon slowly and let it put up i don't know but i'll look into it a little bit um other than that unless its the paper is weird it's just printer paper i don't know but he's on it
00:32:58
John Saunders
Yeah.
00:33:02
John Saunders
Yeah, I was to chat GPT, there's no like easy.
00:33:05
johngrimsmo
so easy answer yeah
00:33:06
John Saunders
No, no, no. It's like, read the label. like Thanks, chat.
00:33:09
johngrimsmo
Exactly. But like, it's supposed to be an inert gas, which shouldn't do anything in the heat or oxygen or whatever.
00:33:11
John Saunders
um
00:33:16
johngrimsmo
Maybe if it is the wrong gas, it is a ah reactive gas, maybe.
00:33:23
johngrimsmo
What
00:33:23
John Saunders
There's a special valve type for argon cylinders that you could check. It lists the US number on it.
00:33:28
johngrimsmo
does that mean?
00:33:30
John Saunders
Argon cylinders use a specific compressed gas association valve fitting in the US called a CGA 580. That's not the valve fitting on your tank, it's a red flag.
00:33:41
johngrimsmo
Not the regulator, but the valve. Like, I don't
00:33:45
John Saunders
Valve fitting. Argon cylinder valve fitting would be, yes, that would be the tank, not before the regulator.
00:33:51
johngrimsmo
know. Got it. Yeah.
00:33:52
John Saunders
I mean, look, I could be... You didn't ask my opinion. i that's Keep an open in mind about that, but like that just seems like one in a million, not a...
00:33:58
johngrimsmo
Totally. Totally. I agree. We are on this podcast to get your opinion. Yeah.
00:34:04
John Saunders
I know, I know, but I tend to...
00:34:06
johngrimsmo
Yeah.
00:34:09
John Saunders
If I was in a group project and somebody was claiming that as the excuse, I'd be we'll keep that in the back of our head, but like let's go like practical.
00:34:14
johngrimsmo
Exactly. Let's say what else?
00:34:16
John Saunders
Yeah.
00:34:17
johngrimsmo
Yeah, exactly.
00:34:17
John Saunders
oh
00:34:18
johngrimsmo
So, so yeah, Larry said, try, try to repeat the result without the paper.
00:34:19
John Saunders
the The goal... got
00:34:24
johngrimsmo
And, uh, yeah
00:34:26
John Saunders
you I don't remember if you post them put them on Instagram or just DM them to me, but the pictures of the um buttons, I believe, that you said were changing their physical shape during heat treat.
00:34:39
johngrimsmo
yeah, I post those in my stories.
00:34:40
John Saunders
look Let me tell you, folks, he wasn't kidding. It looks like somebody took a trip and smacked him.
00:34:43
johngrimsmo
Yeah. Like ah a ball peen hammer and dented this thing. Yep.
00:34:49
John Saunders
That is... I was shocked.
00:34:50
johngrimsmo
It's super whack. like And oh
00:34:52
John Saunders
Yeah, that wasn't like a sag or a little bit of... gravity Gravity flow.
00:34:56
johngrimsmo
and we're super gentle with moving them, but I think they are so soft at that critical temperature compared to any other steel.
00:35:03
John Saunders
the
00:35:04
johngrimsmo
They're like clay, like literal Play-Doh.
00:35:08
John Saunders
Play-Doh.
00:35:08
johngrimsmo
So... So I have a machine graphite fixture. It's ready to go. But but Larry is super hesitant to run it without getting this argon situation figured out.
00:35:13
John Saunders
Looks awesome.
00:35:20
John Saunders
You need argon to run a graph, head or all have a problem?
00:35:23
johngrimsmo
So graphite is fine in a vacuum up to 5,000 degrees Fahrenheit, but it doesn't like oxygen above 900 degrees Fahrenheit.
00:35:31
John Saunders
Okay. Well, it sounds like you just figured out a way top you have argon.
00:35:34
johngrimsmo
Yeah, exactly. Destroy my...
00:35:37
John Saunders
We'll put it, run a cycle with a scrap piece of, you have any scrap graphite left over?
00:35:41
johngrimsmo
i could I give him scrap blades that he can keep testing on um no I don't have any extra graph i I have extra blocks of graphite but exactly yeah that's that's interesting yep we'll touch base next week stay tuned next week
00:35:51
John Saunders
How about a pack of pencil lead? Interesting. Interesting. Okay. We'll keep it posted. It's very interesting.
Review of the Gorilla Stand
00:36:00
John Saunders
Yeah. yeah um I think I tried to end last week's episode with a sort of a fake cliffhanger about the Gorilla Stand.
00:36:09
johngrimsmo
ah yes I saw the little video you posted up.
00:36:11
John Saunders
Okay.
00:36:12
johngrimsmo
That was great.
00:36:13
John Saunders
Yeah. So we put that up on Insta. it's I like it.
00:36:16
johngrimsmo
kind of agree.
00:36:17
John Saunders
It's high quality. It is the Herman Schmidt that we also have is is too small. This one is too big. I mean, I think it should be
00:36:24
johngrimsmo
ah kind of agree
00:36:26
John Saunders
30 to 50% smaller, it would maintain the benefits for all practical purposes of having a stable platform and the ability to, to you know, bridge over a part without, um you know, even on a 24 by 36 plate, which is bigger than some shops can kind of have, it's it's large on a, and it would be very,
00:36:46
John Saunders
borderline impossible to use on like a 12 by 18 or even 18 by 24 plate. So, um, and then knowing I don't like, I don't know if maybe I'm missing something obvious is that um when you rotate the knob to loosen the whole, to the two bars, there's a vertical bar and crossbar.
00:37:04
John Saunders
One knob releases both of them.
00:37:04
johngrimsmo
yeah
00:37:05
John Saunders
And it's great. It locks up very crisp and very securely. But when you unlock it, you have to have one hand to unlock it and the other hand has to support the whole system or else it all just collapses down.
00:37:12
johngrimsmo
yeah
00:37:16
John Saunders
And that is awkward. And it's something that somebody else will end up probably dropping an indicator onto a part because they don't realize it's as sensitive as it is.
00:37:26
johngrimsmo
yeah it's like fine when you know what you're doing but if yeah you're right um that is an interesting uh
00:37:26
John Saunders
that make sense?
00:37:29
John Saunders
yeah
00:37:33
johngrimsmo
Feature, not a bug, let's say. But it's, yeah, it's I agree with those points.
00:37:42
John Saunders
What do you think? Comments?
00:37:43
johngrimsmo
I think, I mean, we have it on, I don't know how big our surface plate is. Probably 24 by 36, maybe. don't even know. It's an old CMM base.
00:37:51
John Saunders
Probably yours.
00:37:52
johngrimsmo
It's got holes in it. um it's good on there because we have that we have a mitotoyo height gauge on it and some other stuff and there's plenty of room and it would be great for bigger parts but we have tiny parts i would love to see the baby brother of this gorilla stand um even with the same amount of weight in the base or something like nice stable but uh yeah
00:38:05
John Saunders
Yes.
00:38:09
John Saunders
Yeah.
00:38:14
John Saunders
Yeah, agree.
00:38:19
John Saunders
And to be clear, um I don't mean to rag on it. It's a well-made product. um We're going to use it. I like it. The packaging was exquisite, um really.
00:38:27
johngrimsmo
Definitely.
00:38:28
John Saunders
um it's It's also, I will say, it's also fully priced, if you will, perhaps, but um well done. Like we wanted to have a tool that would work to use with confidence to use our most our most high resolution tools.
00:38:36
johngrimsmo
Mm-hmm.
00:38:45
John Saunders
Like we have two millimuses, we have a 50 million sprung and sharp. and with with the Gorilla stand, we can very comfortably, as I showed on the video, you know, we can go to the value you want.
00:38:55
John Saunders
There wasn't hysteresis. It's just a very solid, compared to like what I used to have, which were eBay, Sterets, and you're just like, every time you're like, ah, I got to get the backlash out or it's got some, you know, hysteresis bumpiness to it and blah, blah, blah.
00:39:06
johngrimsmo
Yeah, yeah.
00:39:10
johngrimsmo
There is a I know you got to go real soon, but there's a hack you can do with this style of indicator that you can't do with some of them or with indicator stand.
00:39:17
John Saunders
Hello. Hello.
00:39:19
johngrimsmo
So how you had it in the video where you have the base and you have the arm sticking out quite a bit and your indicator on the tip, not just around, but which is an option. If you flip it, um okay, so you have your your two feet, that's your pivot point pretty much, and your one foot in the front that you're up and down.
00:39:35
johngrimsmo
If you get the indicator sideways to be in line with the two feet or just out of line with the pivot point of those two feet, now your accuracy goes through the roof.
00:39:44
John Saunders
It's a sign. <unk> kind It's a compound on a lathe for a diameter.
00:39:48
johngrimsmo
Exactly, yeah.
00:39:49
John Saunders
Love it, John.
00:39:50
johngrimsmo
So you can use the knob and literally move like one million at a time, which kind of silly, but kind of awesome at the same time.
00:39:51
John Saunders
That's super smart.
00:39:55
John Saunders
There's of course.
00:40:00
John Saunders
Well, no, I totally agree.
00:40:01
johngrimsmo
Yeah.
00:40:01
John Saunders
Okay.
00:40:02
johngrimsmo
And imagine if you put it out like two feet or however long the thing goes, you have a lot of travel, but you have very low resolution.
00:40:10
John Saunders
Yes, right, right, right.
00:40:11
johngrimsmo
And I saw Nicholas Hacco mentioned that on some private video a long time ago. And I was like, oh, that is that is really cool. I need an indicator stand that can do that. This one can.
00:40:20
John Saunders
Yes. Okay. I'm glad you mentioned that. I'm going to make a note to play with that.
00:40:23
johngrimsmo
yeah
00:40:24
John Saunders
um Use gorilla at an angle like a lathe compound. Okay. Yeah, i got run.
00:40:31
johngrimsmo
Okay.
00:40:32
John Saunders
I'll see you next week.
00:40:33
johngrimsmo
See week, man. Bye.
