Not ultra critical at this stage. It's basically a bushing for a bushing. It gets turned down on the OD for an interference fit on an existing bored hole and the ID just needs to be blasted out to a little over 4 and a half, then it gets welded in place and final line bored later.

I've never even heard of a gun drill but hot damn if that doesn't sound like the perfect pilot hole tool. Honestly I'm trying my best to make due with what the shop already has while recommending tools I've used before in machining. Last place I was at we had this wicked set of spade drills from like half inch all the way up to 3 inches and change that would tear through metal like butter.

At this shop, their last machinist quit 7 or 8 years ago and mostly I get blank looks when I ask if they have x or y tool/insert/tool holder. The owner is willing to buy new tooling but I've never been in the position to even select tooling for operations before, let alone outfit a shop for every process they want to run.

 

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?

Iirc the closest modern day relative is some form of sea slug. How you go from spore to slug has got to be a wild journey

That's where you've got this whole concept fucked up. You can say whatever you want. You cannot say whatever you want in any manner that you want. It's ALL about time, place, and manner. Time, place, and manner restrictions have always and will always be a part of the freedom of speech.

You're an idiot. You have the freedom to speak in whatever way you want. You do not have the freedom from the consequences of misusing that very same speech.

In exactly the same way you have the right to bear arms but do not have the right to use those arms to attack your fellow citizen.

Happened all the time. It just depends on the environment. Check out basically anything on the "Tully monster" if you want to know more.

Tully monsters are actually even older than OPs fossil and we have no idea where they came from or where they went, from an evolutionary perspective.

Pot is entirely legal in CA. Stoners are some of the most cautious and calm drivers on the road anymore.

The guy just tried to kill a dozen people in a drunken rage and you think he should get a pass because the crowd caught him?

Fucker is lucky he wasn't physically pulled into pieces.

A bullet hole is the least of his worries right now.

What about an opposite bridge where you cross under the river? Some sort of tubular subterranean structure. We could call them opposite bridges.

If people are learning, why is trump ready to sell off public land for resource exploitation?

All whites are bastards

Good thing whites aren't a race. They're more like a conglomerate of historically privileged socioeconomic groups. ESPECIALLY the colonizers. Their whiteness is basically tradition at this point in history
