"....My colleague in the machine shop drilled the shaft crooked (on a drill press!) So this new shaft is kaput."

Redrill the shaft at rite angles to the bad hole.
THIS TIME DO IT RITE!!!!!
Take a MILLED square block of steel or Aluminum and drill a guide hole in it for the pin drill size and a guide hole the size of the shaft at rite angles to the drill pin hole just drilled. Locate the shaft in the block and put it on the drill press (or mill) and drill it.

IT's called a Drill Guide!!!! I'm not a master machinist. I'm not a master of anything. But anyone who claims to be a professional machinist should have known to do that.

EDIT: The gear itself could have been used as a Q&D drill guide.
