It is with complete shame that I admit that this is the kind of stuff that's been going on at work lately... The part is a large cast iron base for an industrial peice of bakery equipment, in which a huge bowl sits, and rotates on 2 pins to tip over, I imagine. Anyways, the holes became oval shaped from wear over time so some machinery repair company brought it to us. It should have gone to a machine shop, not a honing shop...
Mistake 1.) Accepting the job and thinking we'll somehow break even. The boss is delusionally optimistic and frequently accepts jobs that we have no capability to handle.
Mistake 2.) Having them MIG weld the holes to build them up. The part is cast iron, so in the weld puddle, crystals of undissolved carbon dissolve in the MIG wire, forming a much higher carbon steel that's as hard as glass, and just as brittle. Not only does it crack as the weld cools and pulls away as it shrinks, but it'll F%^K up even carbide tooling in a hurry. The surface is about as round and smooth as a log now.
Mistake 3.) As a machinist, I suggested putting the part so it reaches up around the table on our Bridgeport so I can bore it round... Boss decides on an impulse that it can't be done, and then demands I set up the drill press as seen above. He refuses to listen to anybody, and insists that it's the only way. After 4 hours of going at it, it hasn't gone anywhere, but the boss is satisfied with this "progress" and insists I continue.
Anyways, I'm more or less convinced that the boss is going senile and has lost most of his ability to reason with logic. He's also become more and more stubborn, refuses to listen to anybody, and insists he's right because he has a masters degree and is supposedly an engineer. The project he's had me work on have already sent one guy to the ER, and we've dropped an 11,000 lb CNC machine off of a forklift because he refused to hire a machinery mover, and he was giving me (bad) line by line directions on the forklift, which he's obviously never driven (I have plenty of time on one, myself).
It's utter madness, I tell you.
