  • 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





  • Even worse, It’s actually two parts the owner insists on doing together and parting later. Could have done two 5 inch parts but noooo, that might have been easy. Lol

    Further, the center of stock on the backside is floating in air. It’s a 9/16 hole that’s a bit off-center, but not enough to put the true center in the wall.

    I’ll try flipping around the part and see if I have a boring bar small enough to true most of the hole from that end. Im confident in my original center, it just seems to have wandered a bit through the material.

    Im not entirely sure that tailstock is aligned just right but the owner is riding me to produce since my first two weeks have been mostly restoring the equipment they have and addressing what can be fixed. The Szim lathe really only needed some minor leveling and some oil, but I put a lockout on the other lathe after I opened up the head and found a bunch of chipped gears. The szim has also definitely been crashed at least once but everything seems to be rigid and true as far as I can tell.



  • 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.
