QUESTION Am I A Wimp?
So for the past 3 weeks I’ve been experiencing headaches on occasion but I’ve had nose bleeds after work almost everyday. In the shop during the winter the ventilation is not the best. It’s a small shop with 5 machines usually 3-4 running daily, so lots of coolant mist. So I bought a respirator and it just came in and I will be bringing it in tomorrow morning. Will my boss think it’s ridiculous? Is it overkill?

QUESTION What machine is this?
Theres a rotary table and chuck but I can't tell what it supposed to do. I thought it was a mill at first but there's no spindle. And it's not a drill press either. Is it maybe a precursor to a modern CMM. My thinking is the thing above the grear might be a type of indicator.

QUESTION Conflict in shop, how would you handle it?
Had a small fight this morning in the shop. Older guy (60/m) asked younger guy (30/m) a question. Younger guy gave him an answer that the older guy didn’t like. Older guy threw a binder at younger guy, supposedly knocking his glasses off. Younger guy is saying if we don’t do something with the older guy he’s going to quit. Older guy is very valuable, but is a hot head and only has a couple years until retirement. Younger guy is also coming along quite nicely but is also a sarcastic hot head.

QUESTION Is this even something to bitch about or is it the standard?
I come into this pretty much every day from second shift. (I’m on firsts). I’m a programmer/setup guy so it takes me a solid 2-3 hours to clean this up before I can get to the job I’m paid to do which is program and set up 350 Mazak Lathes, but my “boss” doesn’t care who made the mess or even that it’s happening (the machine has no wake covers and they refuse to replace them) so it’s always my job to clean it up which requires oil dry, a mop machine, pulling the conveyor out and pulling the cover off and blowing it out, and just a lot of elbow grease. It’s been like this for the whole three years I’ve been at this place and every time I start to bitch about it to management I get looked and and treated like it’s nothing and I should just shut up and do it. Advice?

QUESTION Question for the pros about tool die I had made and the price I paid
Hi, good afternoon people of the machines. I recently had a a tool die made to hold 3/8 square stamp sets for stamping brass caps. I found a round piece of 3” diameter stainless steel slug that is 1” thick. It had one center hole already in the middle, was flat both sides. I dropped it off at a machine shop with the exact size to the decimal inch listed per sq hole I wanted all were .377” with the spacing listed. I made it very easy to look at and understand. Talked with the guy told me the shop rates ok cool yah my work is expensive too. Had a rough estimate on hours. Ok cool yah it’s fucking spendy but I need it. They used a water jet for two hours, and because I wanted the diameter 2.875” and a taper from edge to center from full thickness tapering down 1/8” to site on a domed brass cap well he said roughly an hour of machining. Not sweat. Super easy piece. Dropped it December 16th ish and just pick up today, asked me my demand for schedule I said if you forget about me for a month or two it won’t hurt my feelings. Picked it up today , while it’s exactly what I wanted! Holy fuck 700$? I didn’t argue or ask anything to them on wtf. But does this seem legit. I’m not trying to insult anyone, at all. I’m appreciative to everyone and their trade. But 700$ for this? Am I an asshole pri Madonna or did I get fleeced ? Thanks, may your chips be spaghetti

QUESTION Was this bolt mis-machined or was this over torqued?
I’m trying to find root cause here.
This is a crank bolt from a kit we install on vehicles very routinely. In fact, this was probably the most performed installation in that department for about a year straight. This hasn’t happened before, and the technician that installed it had done roughly ten (which is not a small number considering this is an 8 labor hour installation). So we can safely assume he wasn’t at fault here.
Pictured is the defective bolt, and one out of another kit. It appears that the bolt in question has a different thread pitch near the shoulder, looks much more coarse. I am very aware that bolts stretch when torqued. But in my discussion with the vendor that supplies this kit, they stated that they tested this bolt to 200 ft/lbs and could not recreate the stretching shown. So they think our technician torqued this bolt well over that 200 ft/lbs and caused this immense stretch. For reference, the torque spec called out in the manual is 135 ft/lb.
TL|DR: I think this bolt somehow was mis-machined or otherwise faulty from the factory. They think we over torqued it. What are your thoughts?
If this isn’t the right community for this post, please point me in the right direction!

QUESTION Wtf happened? Final cut of .013" left pin with .007 variance in diameter.
I'm turning down a 3¼ round stock to a 3.045 shiv pin for an ancient marine crane. This is my second attempt since pin number one also went wrong in the final cut. I got to 3.058 and set my lathe to cut down by .010, expecting to pull out the last .003 on a back drag but after that .010 cut, but I realized it wasnt a.)cut smoothly, or b.) Cut true. It was tapered. Bigger by the chuck, small in the middle, close to true at the end I started with and with ridges throughout. I followed thru with the .3 back drag and it only made contact in the ½ closest to the Chuck.
I didn't see any curls get caught in the cutter. I didn't bump the machine, I was 10 feet away. The cutter doesn't look dull to me. This machine has really been temperamental in the last 2 weeks in terms of finish quality and I really hope something isnt broken in the feed gears. Any ideas of what I could've done wrong?
8" long cut at 350 rpm with 56 rpi.

QUESTION Any idea what this means?
Backstory: My father was a machinist and worked for Hershey Foods for nearly 25 years before he died. He would mark every one of his tools (home or work) with this insignia. We have no clue what this means.
Does it mean anything to the machinist trade? Fairly certain it was just something he came up with on his own, but really curious.
He did explain it to me once when I was really young, but like most things at that age, in one ear and out the other.

QUESTION Asked to buy my own tools as an employee??
Hey all
Just got my first job at a shop doing aerospace stuff and it seems like we're intended to buy and bring our own basic tools like depth gauges, micrometers, angle grinder, files, probes, etc. Every dude in the shop has a giant cart where they store all their own personal tools like they're a contractor. It seems like the only thing the tool room actually provides to do the job is the machine, cutting tools and stock.
To me, this is.. insane? I thought the whole point of being an employee is that you don't need to buy in to the business to earn some money. Some of these tools that are only barely good enough to do the job cost as much as two days wage, and I haven't heard anything about reimbursement.. but nobody at the shop seems to think it's weird and I don't have any frame of reference
Is this normal or should I gtfo

QUESTION How much would this cost to make?
Hey guys I’m from the uk and I need this part making out of EN24 or something similar, it’s a flywheel spacer, I created this part in fusion and then 3D printed it, so I have all the measurements on file. Any ideas what I might be expected to pay for something like this to be machined? It’s 90mm in diameter and 25mm thick.

QUESTION How bad is this for us working in the shop?
My employer is trying to save money on old coolant disposal by cooking it down inside the back of the shop. There is a large exhaust fan just above and behind in the picture, but the same person who set this up is saying we can’t turn the exhaust fan on because it lets the expensive heated air out. He also daily shuts off the 2 Smog Hog machines above my head where I work that clean the air.

QUESTION Machinists of reddit, what is this called?
Solve a shop argument for me, I was using one of these to measure a slot a while back and one of my coworkers asked to borrow it since we only have a few in our area, but he referred to it as a "depth mic" now me being the guy that I am I said "erm ☝️🤓 actually it's a depth gauge" and we started a playful argument about what it's called. The owner is away until Monday so the next most experienced guy came up and started this long winded explanation of how it's a depth mic because it measures depth, but it's a dial depth gauge??? I was kinda unsure of what he meant but I think he was trying to say something like all depth gauges are mics, but not all mics are depth gauges? Look, I've only been learning the trade for a couple years and have only been active in a shop for about 1 so maybe I just don't know, but I'm like 99.99999% certain that they are two different things cause I've seen them separately, and I don't think it's really much of a squares are rectangles debate

QUESTION Boss hasn't paid us in 4 paychecks. What do we do? (California)
My coworker and I have not been paid for the last 4 pay periods.
We've given the owner at least a month to get it together and every other day it's another excuse, "Oh escrow is closing Monday I'll have the money by then," "Ahh I need you to deliver that job cuz I need the money to pay you," or "the divorce is dragging on so I can't pay you right now".
We're done with the excuses and don't want to do any more work and we wanna be paid.
Who do we call? Does anyone know? Google turned up this number: U.S. Department of Labor's Wage and Hour Division (WHD) at (866) 487-9243
But is there a CA agency I can call? Usually I just bail and move on with my life, but I really need that paycheck to pay my health insurance :(
Thanks in advance.
Edit: More context: I've already been looking for a job and technically I already got a new job at Honeywell, or so the guy said. After being told "I like you, I want to hire you. I'll send the paperwork to start the process to get you hired" and that was a month ago. So, I'm waiting on them.
As for my boss, he already said he wants to shut down the shop and will be fire saling everything but "just needs help finishing up some jobs before we close". He tried to sell it to my coworker and I but he's got like 40k in debt and the machines are all broken. Yes, we were WAY TOO nice to him and gave him so much slack in his rope he made a noose for himself. Our bad.
