JoeZ, I understand your problem better having read the other posts. I had thought the shaft was stuck into the mount.

Not being argumentative but have you thought about what's actually holding those two flat surfaces together? In my mind's they cannot be holding themselves together with stickon alone, something must be keeping them pressed against each other. The only candidate are the threads, just like jamming two nuts against each other on a bolt. You'll have to lubricate the threads with something like WD-40 or warm in the Sun to get them free, probably both.

I don't envy your problem, have fun with the mechanical side of our hobby...joe :)

Hi Rich & Joe M.

I don't think that the threads themselves are actually the cause of
jamming the shaft stuck to the DEC shaft adapter (mating) flange.

When this happened to my AP-900 mount, it seemed to me that the "flat
end annulus" at the end of the shaft was jammed up against the similar flat
surface of the adapter. Effectively, this is surface to surface "stiction".
Perhaps applying Chapstick to the flat mating surfaces might prevent a
reoccurrence of this, acting just like a Teflon washer. Then again, I wonder
if something equally nasty might happen with frozen Chapstic in winter.
However, I don't like the idea of anything greasy on parts that an errant
hand or fingers could contact during mount set-up, and might transfer to
optics, etc.

Joe Z.

Sorry about the "empty post".

Once you get the shaft un-stuck, a little Chapstick on the threads
works wonders.
