has anyone suggested that it could be as simple as a cracked bearing ball?

Oh, I think a cracked ball will go from bad to worse at a very rapid pace.
Possibly a dinged ball in the backgear assembly (like when it ran over the
bits of the retainer cage) could just get noisy and stay that way for a long
time. That's the kind of shape my back gear bearings were in, and they
generally made a loud whirring noise. But, a really cracked in half ball
ought to be fairly disasterous.

Bridgeport heads are not loaded heavily enough to crack a ball. So it
one was busted..it was a flawed ball...and they are very very rare.

Did the OP track down the noise with the screwdriver stethescope?

Where was its home?

gummer was back at his squat by 6:00pm this evening, as his reply above
shows. It's very odd he hasn't made any of his usual intemperate and
absurd replies to the posts elaborating what a stunningly stupid loser
he is. I know he has seen those posts. I wonder if maybe - just maybe
- the message of what a massive loser he is has finally struck home, and
he realizes there's no denying it? It seems highly improbable, but I
suppose stranger acceptances of reality have occurred previously.
