My clamps were mostly OK but the bolts and screws and threaded rod weren't. Had to run a die over pretty much everything and a tap through the T-nuts.

All in all compared to some of the stuff I had to deal with from the previous """""machinist""""" that was working at the shop I'm at, it wasn't so bad. Don't get me started, my blood pressure rises just thinking about it.

I kinda get it.

Follow up to >>111631. My new guy leaves to go have a baby or some lame excuse, and senior guy shows up to help. I kinda need his help for a few things, but most of the startup I'm fine with. While I try to do a thorough job and take advantage of our time on site, he just wants to fuck off and smoke in his truck. "Hey man, lets go smoke." "Nah, we got plenty of time." "Don't worry about that shit."

So electrical powerup is my olympic sport. He's more of a mechanical guy, but has like 10+ years of doing this. Working with him was like taking 3 steps back, and then wrapping an anchor chain around my waist. I basically have wait for him to fuck around trying to troubleshoot until I can get by him and actually figure out what's going on.

Then it's off for more second hand smoke.

My biggest problem with this guy is that I can't trust what he says. We joke he's 110% sure about things. 100% confident and 10% correct. And he's not lying, because he believes what he's saying. He just mis-remembers, or didn't understand, or connected two things that don't actually connect. Maybe too many drugs when he was younger?

There's some shit that I flat out ignore him on...

"Nah, we don't have to do that shit. It's gonna cause it to seize."

He'll have some bullshit idea, then credit it to someone else. That someone "told him". Either the supervisor, or the site boss, or an engineer in the company.

And if you call him on his bullshit, he'll just deflect it, or say that it applied in some specific scenario.

Big customer sent us a drawing of a part. Supervisor sends it to the laser, looking at what the part is for, that was the correct call.

Part needs a few threads so I get it after it's lasered. I look at the drawing and see ridiculous shit like "holes [true position] 0.002 A, B", long story short they tolerance'd it pretty much 15 times too tight as the part would require. It's basically a plate that would hold a thing with regular bolts, it could be off 1/16th and it wouldn't make a fucking difference but blueprint is a blueprint.

So they chuck the lasered parts in the scrap bin and ask me what do. I say the drawing is dumb but if they want it to print, laser it out with extra material so I can just clean up the lasered surfaces so dimensions, locations, surface finish and other GD&T will be bang on.

What you see is a little re-pass just to adjust cutter compensation after running the first part. The lasered "blank" thing is held down with a few bolts undersized from final hole size, the outside is machined, the clamps are installed and then the screws are removed so the holes and threads can be machined to match the other features. Yes I deburred the plate that the part is sitting on after taking it off.

tl;dr that particular webm was what happens when a big company with lazy engineers throw money at stuff.

Friday was a heavy mechanical day, and warmer, so coworker actually hauled ass and we got a lot of work done.

Today, the electrical inspector comes up to me...

> E-Insp: Hey, did you hear about [Customer Startup Specialist]?
> Me: No. What happened?
> E-Insp: He had a minor heart attack. He's at the hospital. He's doing ok. But they keep calling him like he's still on the job.
> Me: Oh fuck. That dude needs to be out on medical. No part time anything.
> E-Insp: Yeah, fuck.

This particular CSS was on a previous, super high stress job, that coworker was on. Apparently it involved millions and millions of dollars of possible late penalties. Their VPs were talking to our VPs, kind of serious. I'm told there was plenty of yelling involved, including the CSS yelling at this electrical inspector, and coworker telling this guy "You don't talk to human beings like that."

So for this CSS to go from running that job, to having some personal life issues, I can imagine he was under a lot of stress. He showed up to our job promising it would be different and that we'd be in no hurry. And everything seemed ok. Now that I think about it, he looked kind of bad last time I saw him. Like his damn eyes were bulging out.

I figured out that I'm never going to take a job with that much stress. It's not worth any kind of money to have a fucking heart attack.

Come to think of it, another plant manager had two strokes. He's alright now, but I think he gave up on working and just smokes weed erry day.

So I made the thing, 0.5" diameter at the large end, part a hair under 1.125" long.

But then it gets interesting.

Please note that the little hole is 0.095" in diameter, and goes completely through the part.

Baffled the old tool&die maker when I showed him this, guy didn't know about setting the lathe in metric and imperial at the same time to move 90 degrees in the 4th dimensional space so you can cut a feature by going "above" the part walls.

Yep! Grabbed an old #8 drill (the internal counterbore is 0.200" in diameter), turned it down until I basically had a tiny stem with two little cutting flutes. Used a dremel with a zip wheel to grind something like cutting edges on the two tiny flutes. Slipped the stem down through the pocket, put the part in a drill chuck, used a second drill chuck to grab the stem.

Spun the part in a drill (in CCW rotation, because it's backwards cutting because of the drill flutes), and pulled on the second drill chuck gently until it cut the internal counterbore.

If it had been a longer distance between the face of the part and the pocket, I would have needed to make a two-part tool with probably a little threaded hole where the cutting flutes could be placed above the 0.095 hole in the pocket, and threaded onto the "shank". Of course, it would also need to cut in CCW so it wouldn't loosen off the threads.

Sure enough, all these shenanigans were so that the engineer could glue in a little wire crimp into the internal counterbore. As much as I suggested to simply do it like five other different and simpler ways, he's the smart one and he wanted his counterbore on the inside so he got his counerbore on the inside.

It's funny, using DMLS, this would have been trivial. I've got some homies that do all kinds of additive manufacturing, plastic and metal, and parts like this are completely normal for them. I walked in one time and mentioned something about a Wankel rotary engine rotor. The guy starts laughing, and pulls out a failed print of a rotor made of cobalt-chrome. It weighed a fuckton.

They do all kinds of materials including Titanium. I guess with a 400 watt laser you can melt whatever the fuck you want.

However, it's not always easy. Last time I was there he was showing me some of the mutant parts the machine made. There's a lot of skill and knowledge that goes into making a part, even with additive.
>> No. 111676 ID: 19518e
>>111675
Yep, additive manufacturing is awesome... Until it isn't, or the settings aren't right. Engineer showed me his prints from his home 3D gluegun, and I immediately understood why he wanted me to machine his things. It wasn't a mess of melted wire, but the part was simply bad enough I was impressed it had even printed completely. Still, I wish I could get something additive, the advantages are clear and measurable when you have really weird geometry and want to just prototype something before you order like 12k monies of custom shape extruded aluminum. I have high hopes for the technique in the future but there are still many massive hurdles to overcome before it could even get close to a lot of old fashioned swarfmaking.

>400 watt laser
Cute! I wish our laser could add material. It's pretty much only 2D contour stuff but at least it's 8000 watts. It's from a while back when additive was but a budding flower and problems were solved with MOAR POWAR.

Still gives me the willies when it's running blazing through half-inch thick steel like it's a hot wire in foam, the windows are clear and it makes me think it'll fry my eyeballs right out of my head just from a reflection of a refraction of a refraction. Not sure how that all works, some guy has been using it for like ten years and he can still see. I'll have a gander at the manual tomorrow or something...

My coworker, the physicist, got a job offer working for a government contractor outside of DC, making more than twice what she's been making here. There was an attempt to get her hired on with a contractor that does a lot of work on base, with similar pay, so she could justify continuing to do what she's been doing, but I found out today that that fell through. She hadn't even been looking for another position. This company found her info on Indeed, brought her in, and basically said, "You are what we want to hire. What would it take for you to leave what you're doing, come here, and work for us?" She gave them what she thought was an insane number, and they went for it. So she basically had no choice but to take the job, at that point.

We've also lost a more recent hire in our group to private industry elsewhere.

The skills the government needs for what we are doing are worth a lot in industry, and the government pay system just isn't set up to account for that. My boss has been trying to make the case that he should be able to get his employees paid more, but he has to show that we've already lost people to industry. It doesn't sound like there's a way to act preemptively. And now we're losing someone that was doing a lot of important stuff, one of the two people who've been working in the labs day to day for this group for more than six months.

And that's when I found out my fucking car is literally 50lbs short of a Dodge Ram Quadcab with the same engine and they supplied the same fucking jack I had for the neon. (which back in the day mind you, didn't fucking fit underneath it when it was fully compressed)

And I keep a goddamned three ton in the fucking thing because of it.

Pretty sure it's just the US going into rampancy because I swear to god there's gunfights everyday in neighboring cities, we're getting a bit more firearms related goofy shit happening.

Like gyms getting shot the fuck up and cops not giving weapons charges to the shooter because of how lulzy the whole situation was.

Oh and to get all four fucking tires off the ground, the car has to be three feet off the goddamned ground.

Suspension is like a weird fucking monster truck.
Though hitting a ramp at 70 in it is comfortable as shit, fuck working on the thing.

Let me tell you about my girlfriends car though, it's a mashup of 6, no shit, 6 different vehicles.
It's the frankencar.

And there's no drain plug for the oil.
There are 5 of these things aside from hers we interact with, like friends cars.

Huh. Never would have thought of that. Of course around here our machines are so beat .0015" TIR is considered good. I had a tool running out .005" because the taper is fucked that I got down to .0017" by yanking on the holder. Yay rigidity.
>> No. 111805 ID: 19518e
>>111804
The smaller the tool, the more concentricity matters. Some operations might be a little more forgiving, but when the tool is both long and skinny, best = no measurable runout.

I've done some really crazy shit to reduce runout. SOP at another shop that was better equipped in cutting tools, but still old machines/old tool holders was to say "hold my beer" and ATC to previous tool, ATC to current tool, dial it, mark the high spot. This ensured the tool would be seated exactly as it would be when the program ran. Then you actually tap the tool itself with a hammer, ATC to previous and ATC back to the tool you're working on. Dial it and see if it changed. If it didn't, tap it harder. If it did and it moved the correct way, you're getting warmer. There's a definite art to this, you usually hold the tool in your fingers with the left hand to dampen the vibrations while also holding a little brass punch against the tool body to prevent damage to cutting edges, then give it a little tap.

You can dial shit perfectly and consistently like this. I've actually only broken one solid carbide 0.125" reamer this way out of dialing tools probably a hundred times. At one job they couldn't get their 0.125 +/-0.0001 hole in (ran oversized), only had on-size spares, and no undersized. After the one broken reamer I had it spinning with no measurable runout with about five minutes of ATC swaps and hammertime.

I did give it a go with the tools I mentioned (10 to 12x extended sub-0.060" diameter shit) but I quickly gave up. I may have a decent bit of experience in precision percussive calibration, but fuck I don't have spares and those things are tiny.

Then there was that time I woke up an old tape-drive CNC Matsuura vertical milling machine for another job. It would chatter on any tool in any feed/speed, I scratched my head for a while before putting a bit of layout dye on a tool holder taper. Ran the tool for a few seconds, when I pulled it out of the spindle, there was clear rubbing around the taper, getting really bad at the larger diameter of the taper. Machine spindle taper was wallered right out (it's why that machine hadn't been turned on in years, the guys that knew this were long gone). Hotdog down a hallway.

Now the correct course of action is to get a spindle regrind. However, they declined this request and so I asked them to hold my beer. Then I used six small squares of masking tape on the tool holder taper to provide points of contact (three points at the bottom of the taper and three points at the top of the taper) and we were able to mill over 2000 feet of slots (slotting with an endmill) without a single whimper of chatter.

I actually don't know how concentric the tape was but it wasn't a super precision job and the tool wasn't very small so I guess it was gud 'nuf.
>> No. 111806 ID: 1519ac
>>111805
Oh I'm no stranger to fixing runout with a hammer. I've used stainless shim stock between the holder and the spindle taper too. I'm lucky in that it's very rare I need to use a tool under 3/16 diameter, and if I do it's usually just for engraving.

Man, I've never had a tenth as many problems with one of these. Normally you turn the damn thing on, hit configure, hit start, and don't worry about it until the roof leaks directly on to the drive 5 years from now...

Those high-power drives and soft starters are touchy things, it seems. We just blew one recently, while testing our switchboard on our final inspection before shipping out.

Apparently Schneider Electric has some assembling facilities in China as well. This engine soft starter is different from others we used to install before - it is not enclosed completely for better ventilation and the circuit board is exposed to the elements (on the photo the front cover is removed).

I'm not responsible for the testing itself at any part, and I'm not on the test site when everything happens. But I'm part of designing subdivision, but I still have to correct minor errors in schematics, if they find one.

>final inspection team is testing the starters after they finished with the rest of the installation
>our schematics for this includes separate microprocessor command and control unit
>and also some relays to transmit external signals
>yet this time the program is not loaded, so they do it in the manual mode
>click on relay test button and watch the starter work out
>the soft starter is supposed to have internal safeguards anyway, including protection and control

>test team programmed the starters for low-power, and used testing engine from the facility
>test team starts clicking in tests with first unit, starting the engine
>received some errors, cleared them
>on third attempt they hear loud "pop" and see a single spark flying out of the unit
>the unit "blew up"
>luckily, in low power mode you practically can not burn anything seriously

They called out to us. After an hour of investigating we found no fault on our side, so we assume it is a manufacturer error. We really hope that no one did something wrong during assembly and testing because we are doing those same units for years already with no problem.

>starting to test second engine
>cleared more warnings and errors again
>who knows wtf really they are doing
>engine starts normally
>rest of the engines start normally
>testing is over and we can not wait any longer before shipping out
>we dismount the burned unit and send the rest of the switchboard off
>other people should figure it out between our supplier and our client from now on

This thing costs more than my year worth of earnings anyway, and there's no way we are fiddling with it trying to fix anything. And, I suppose, it is a good thing it blew up on us, not on site under 100+ kW load.

The new guy at work bought his BMW by slinging dope, does coke, and works for an illegal bookie, and I know all this because he told me. "I can tell you're cool though, bro. I can tell with people." While his antics started out as amusing (getting drunk at work, being socially oblivious to the irritation he causes others, going on a bender and losing his car. Like literally lost. He couldn't find it), things took a darker turn tonight. He's mentioned earlier that he doesn't like snitches. I assumed he just meant tattling to the store manager about store shit. But tonight I saw him handling his "business" in the store, soliciting customers, having bettors visit him at work, threatening people over the phone that owe. His oft stated opinion on snitches was reiterated several times tonight. I stiffened when drunkenly threw an arm around my shoulder and again reassured me "but you're cool, man. I can tell with people."
I want my fucking guns back.

New job yet?

>>111430 >>111095
The West Virginia job strikes back. Shot a 3-gun a few weeks ago and my knees went to shit. Probably all the standing and running around after sitting on my ass for a month with no jobs. Shot a rifle class on Saturday where I had to sit down any time I wasn't doing rifle things. I figured if it didn't get any better I'd go see a doctor, which would most likely result in surgery and my ass being down for months.

My knees started feeling better Sunday, and have been doing ok this week at work, even doing maintenance with a good amount of climbing up and down. If it gets worse, I'll go see a doc.

Other than that, last week was pretty sweet.
Mon, drive 5 hours
Tue, defensive driving class
Wed, first aid class and performance review (with better than average raise)
Thu, job canceled, chilling at home
Fri, trouble call, had it fixed in 5 minutes, talked about guns for 4 hours
Sat, rifle class

For the defensive driving class, we got to learn from racing drivers how to hustle some crown vics around a race track, how to brake, drift, and avoid plastic children. Lulz were had. Apparently they had some cops in one of the previous classes and recorded video of them doing one of the events.

> instructor, 2 officers, 1 chief in the car
> chief is driving
> chief is not a wheel man
> object is to speed into a section of cones at 55 mph, swerve to avoid a plastic child, then come to a stop in the box after the cones.

They played the audio for us:

> *engine revving*
> *tires screeching*
> *thump thump thump*
> *officers laughing*
> *thump thump thump*
> *officers break into raucous laughter*
> *thump thump thump*
> Chief: SHUT THE FUCK UP CHARLIE!
> *officers positively losing their shit*

The rifle class was not work related. The guy who runs events for our club was career Army and did some high speed stuff, and this was the "advanced" class. Did a lot of transitioning between pistol and rifle, shooting from cover, shooting weak side, and communicating with others. Nothing too crazy, but definitely good stuff.

My shirt smells like jet fuel... I probably should take a shower...

I want to take a titanium (jewelry) ring and make two cuts, effectively removing a portion of the loop. I'd like the line distance between the two cuts to be 5.5mm. Tolerance for this dimension is "the closer the better" as I'm going to adhere magnets to the cut edges and want to maximize pull force between them. not sure yet the wiggle room because I don't have the magnets here. would prefer a clean cut if possible without deforming the ring.

the thickness of ring is 1.2 mm. bonus I only have a bench vise, a hand micrometer, some cash, and social skills to work with i.e. I can find stuff. figured one of you might be able to chime in with something inexpensive and effective.

You can get pretty damn close with a hacksaw and a file. oh, and dial calipers are your friend.
Actually, make that two files; one coarse-pitch for hogging out materiel, and a fine-pitch for getting to final dimension.

The hacksaw won't make a very clean cut, but that's what the files are for.
Cut your gap as close to the 5.5mm as you're comfortable with (and remember the saw will cut wider than the thickness of the blade!) then file it the rest of the way.

>Tolerance for this dimension is "the closer the better"
Dial calipers are accurate to within ±.001" (that's 0.0254mm)

I'm sure there's somebody smarter'n me that'll come up with a better method (like milling it on a clapped out Bridgeport) but hey, this will work if you're careful and patient.

I'll second a little hacksaw and files. You have one single thing to do, not a huge amount of material to remove, and you're on a budget. Make sure your vise setup is very solid, it'll make everything easy and painless. Use a fine tooth metal cutting blade, don't bother with a super magic carbide fantastic expensive shit, you don't have much material to cut. Just stroke slowly and you'll never burn the teeth on regular saw blade. Titanium isn't magic, it can be cut by HSS or even hardened high carbon steel just fine.

Paint over the target area with a sharpie and scratch an approximate 5.5mm so you can stay between the lines. You can use a file to make a score on the ring at the spot you want to start the saw cut so the saw doesn't wander when you're starting the cut.

One thing though, when you cut the ring through with the saw, remove it from the vise. It may have some internal stress and spring in some direction or another, so make sure it can move around before cutting the approximate gap and filing it to size. It might not move at all but it's better to check than cut it all nice and then undo the vise for the part to suddenly banana in some way.
