Harold, what's this I hear you're reluctant to put Colchester bearings
in your Graziano? :-) Graziano thought they were good enough..

Tom

Chuckle! Not really reluctant. Just too poor. Mind you, I have no
quarrel with Gamet bearings (which is what Colchester used). This
old
retired dude is looking for something more affordable, but I wouldn't
hesitate to buy the Gamet variety if all else fails. The original
bearings served me well----and owe me nothing. They're still very
serviceable, but I'd like to eliminate the .0002" runout that I didn't
used
to have. Many think it's no big deal, and I can't argue with them, but
when you know it can be better, it's hard to ignore.

The number of jobs I ran with only a couple tenths tolerance are hard to
forget. I've always considered myself a good lathe hand, but not good
enough to work without a tolerance! :-)

Larry Jaques suggested I'd have a hard time putting anything on Mars
with
that much runout. If I can't trust Larry, who can I trust? g

It's like owning a Ferrari, generic parts don't exist,
so one has to suck up the damage to one's wallet. :-(
BTW, Colchester use Gamet bearings because they own them.
They don't come cheap for Colchesters either.

Tom

Yeah, I was surprised to find they weren't French owned. The name is a
real sleeper.
I learned it's a good idea to shop----the latest contact was considerably
lower in price than I had been quoted before. Gunner really came through.

The supplier is checking to see if there are any substitutes, but I'm not
holding my breath. The thought was to get away from the high speed bearings.
My machine runs at only 29% of the speed ratings of the Gamet bearings.
Could be I could use an angular contact bearing in place of the originals.
Could be I'd be asking for trouble, too. Any thoughts on that idea?
