i had bought a second CNC Excello 602 for parts. My main machine needs
a tighter spindle so I took the old head apart today. I'm glad i had
an old unit to learn on, it was tuff going. I had to make up a couple
super special tools and spent more time machining than wrenching.

I learned the spindle cartidge can just be dropped out without
removing the head, big time saver on the main machine. I'd kind of
like to replace the lower bearing seal on the hi/lo gearbox but that
means removing the head so I'll likely skip this part.

When I finally got the spindle cartridge apart, little ball bearings
fell all over the floor. A couple evaporated into thin air. I guess
thay aren't good enough to re-use anyway.

I need to order bearings, the manual calls for:
2 each 7206 CTC/C78G05
1 each 7010 CTC/C78G1
1 each 7208 CTC/C78G

I can order locally and PAY. Anybody suggest a lower cost bearing
supply outlet?

It has been a while since I ordered any bearings, so I don't know the
status of these companies. But look for Reid Tool Supply or W.M. Berg inc.
