Natural diamonds are quite shit for industrial use. Industry likes uniformity, and natural diamonds have irregularities and flaws that do not benefit them in comparison to synthetic diamonds.

The original intent of the stop was a headlight violation.

The problem with that is that it wasn't raining, invalidating the reason for the stop.

From that point forward, the interaction should have immediately stopped. Without PC for the headlight violation, the police had no authority to demand ID. Since they couldn't demand ID, they didn't have a reason to arrest. That invalidates the resisting charge.

Start to finish this was a crazy interaction and I hope every cop involved has a very happy get lynched in front of their families. :)

It's very hard to tell with this guy, probably because he's an engineer first and the owner second. I grew up around a bunch of gas and electrical engineers, so it's not too terrible for me. Some of the other guys in the shop very much struggle with communicating with him though, which is understandable if you don't speak engineer.

Sometimes I throw out a tooling suggestion and he shoots it down immediately. Today, I pitched getting a Darex auto tool sharpener and he's all aboard as soon as I told him the local coast guard base had one. I never really know how he's going to react to things lol

Total bore is a little over 4.5, so I had a ton of material left to correct the hole. Biggest struggle was keeping the tool pressure low so the drill didn't spin in the tailstock. Morse taper is all chewed up, which was a nasty little surprise for me. Got'r'done tho

Next trick: figure out how to mount a 2.5 inch boring bar on a turret with only a 1.25 ledge on it. Im trying to talk the owner into fabbing a holder in house.

Also we found out the morse taper in the tail stock is all chewed up so we're going to look for a morse reamer to correct the tailstock.

This job is certainly tightening up my machinist chops. Im already looking forward to tig work where my tolerance is like +/- .030 lmaoo

Success! Flipped it around and started a couple inches with a stubby 3/4, then I got an extremely stout 1 3/4 to redrill the hole nice and straight. Once the first couple inches were started it was rigid enough to follow its own hole all the way back through.

So as the title says, I've been a welder for 15 years, and now I've been hired into a machinist position, but I'm running the machine shop in this business. I've done machining work related to the welding I've done, sometimes even working as a machinist when the welding work slows down. My last job was 90% machinist work with 10% welding repair.

Now I'm expected to be a full machinist and run a whole machine section (2 lathes, 2 mills, and an entire wall of disorganized tooling) by myself. To the point where I'm the only guy in the shop that can figure out how to set a power feed on a lathe or mill. It's a little overwhelming tbh. But I'm struggling through.

Today's challenge: drill and bore a hole through 10.5 inches of 1018.

What I've done:

chucked up the material in the 3 jaw on the lathe

beat around the stock until it was running mostly true (as far as can be read with a dial indicator on mill scale)

Center drilled with 3/8 center drill (only center drill available)

Proceeded to drill through with 9/16 because that's the only drill we had that was long enough

My problem now:

When the drill popped out the other side, I can see through my spindle it's maybe 1/8 off center. Definitely wobble as seen from the back of the spindle.

How can I correct the straightness of my hole? The plan was to step up to 1 inch then 2 inch drills to be able to fit in the big boring bar, but i don't want the bigger drills to follow the pilot off center. Does it matter? Can I just feed the bigger bits slower and the problem will self correct?
