Re: Bearings don't fit (Drill rod) shafts ?
Went to run our Cim-Sim's from andy mark this weekend, and found that the shafts were so oversized that they had broached when forced into the bearings and were causing the bearings to lock up.

I used our arbor to press the shafts out, then chucked them in the drill press and move the belt to the high speed position. Then I took one of our fine files and turned the drill press into a temporary lathe to take off the couple thou required to make it a nice smooth slip fit.

Took me about 20 minutes, but the AM shaft is probably mild steel, so you may want a more aggressive file.
