Do you have a high-speed mandrel? Ideally, 10-15k rpm. Something I can
drive with a flat belt and attach a cut-off wheel. The one I have spun a
Barden bearing and ate-up the cast iron.

Hummm....No, I sure dont.

Can you open up the bearing housing and use the next bigger size bearing
and sleeve the shaft?

Let me ponder on it a bit and see what I can come up with. Let me know
if you find something on your end before I do.

Heh, heh, I'm pretty sure my dog is a liberal - he has no balls.

Somewhere around here is a "Hiel" grinding spindle...I just have to find it.
I'll see if there's enough meat to install a larger bearing or bore it out
for a sleeve. My experience with high-speed stuff is that it doesn't
tolerate much misalignment. Whatever I do, it best be PERFECT! ...or it
will shake the dust off of the rafters.
