RE: Drilling wheel hubs out?
You know, I bet a bunch of you think this is overkill but.........
Years ago I lived in a big town. There were a couple of industrial supply houses. They looked to me like big NAPA stores only they sold lathes, mills, etc, and all manner of bits and machine shop supplies etc. I was trying to make my own pistons at the time and needed accurate holes. Reamers are the answer, not drills. Those supply houses sold every size imaginable. I decided to buy a couple in sizes that would help those simple tasks, like getting accurate wheel/axle holes.
Since I've never been real happy with running a drill bit into those plastic wheels, it's almost impossible to get an accurate hole, I've been happy as a fly on a pig's lips to sit and turn that "expensive" reamer by hand.
I've not looked, but I bet there is at least one internet site for reamers, real "industrial strength" ones. Mine weren't much more expensive than the drill bits you see on the wall at Home Depot or Lowes Home Improvement.
