This is in answer to Jon's questions on removing a Bridgeport spindle.

Be careful of the set screw(s) that hold the big nut (that
holds in the cartridge) from rotating .  The set screws bear 
on the threads and if you turn the nut without removing them, 
you have a real problem.

The spindle cartridge should pull out.  It is a hand-press fit into the
spindle housing.

There are three bearings in a normal Bridgeport spindle . . . two on
the bottom are class 7 bearings (207's he thinks) and one on the top
which is a 6206 and can be an off the shelf or class 5 bearing depending
on your preferences.

Best regards,
