RE: bearing fits was silly machinist / leadscrews forever

Chris,

Whole BOOKS are written on bearing clearance/press fits! And don't

they do make sense, but this is NOT a "short answer" subject.
Spesh'ly with 780 people lookin' on...

So, anyone else care to go first ?

P.S. I'd visit your friend and tell him the particulars. Ask his
advice.
