Yep, I did just that and was able to loosen the hex nuts.  Once I got the one side done, I was able to shove the shaft far enough in the other direction to expose the hex nuts and remove them as well.  Problem is that the shaft will still not come out.  The collars on both ends are free wheeling and the shaft turns freely.  It looks like the collars are integral to the bearings.  I really don't want to force the bearings out.  I may never be able to re-insert them.

Seems that the RA shaft bearing are the sealed type.  Was advised that if the bearings are smooth and the shaft is sound just leave it be.  Guess I'll just prep the surface and rattle can it.  Was thinking powder coat, but that involves heat that may be detrimental the the bearings.  May still consider a Sodium BiCarb blast and zylotone paint.

Post a pic.  I have the portable model with casters.  I also have levelers, but they don't look original.

Cave Astrola 10-inch restore is coming along.  However, the RA motor is toast.  Any clue on a replacement option?

However, someone on Astro-mart advertised that they had some and I bought one from them. In New England, and the money was going to a non-profit. I'll look up that info. About two years ago as I recall.

It's a Bristol model 447, 1-rpm, with 1/8" shaft as I recall.

Thanks Terry.  I was fortunate that someone in the Vintage Telescope Facebook Group had one he's sending me.  I still would like to have the source for future though.

The little Boston gear on the shaft is difficult to find. I am looking for a couple of those for two Astrolas I have.

I'll let you know if I come across any sources during my rebuild.  I scored an RA motor from a FB post.  Ask the question in the Classic/Vintage Telescopes, Vintage Telescopes, and the Cave Astrola FB Groups.  You can try on C...N as well.  They have lots of Cave owners posting there.

Thanks Darian.  I still need to soda blast the pier and pier legs then paint.  Then we start work on the clock drive.
