/diy/ - Do It Yourself

Anyone else here work with both helpless retards and usually intelligent guys that often have full retard moments?

Had the shop manager the other day tell me a small T handle hex wrench would tighten a machine screw more than a normal L key and then forced me to put an endmill into a collet past the start of the flutes to "make it shorter and more rigid". Then the shop clown cut a V into the top of a stripped screw instead of a square channel and wondered why it kept slipping.
