Improving Polar Alignment Adjuster Mechanics

Works like a charm. No need to loosed the attachment bolt, you can keep it tight. Alt-AZ adjustment is easy.

The CGE uses an internal adjustment mechanism whose problem is the very coarse adjustment mechanism itself as opposed to two painted metal plate rubbing together. No at all the same problem as a CGEM or Atlas mount and cannot be solved in the same manner.
I think it is a universal problem with all mounts that have azimuth bolts including the AP900/1200. I believe the Paramount MX/ME II mounts are exception. They don’t have azimuth bolts.

The polar align routine went from a 10 minute ordeal to a 60 second operation.
Thanks for the inputs!

I think the existing bolts are M5 or M6 x 1mm.. if re-tapped for M8 x 0.5 you'd immediately get twice the resolution.
Also the bolt handle if it had ridges would be better. for example on the Mach1, the bolt handle has lots of ridges on it, so you get precisely 3 arc-min per ridge. the CGEM just has this cheesy round-ish bolt handle, don't know about the DX. i guess ADM handles would do better here but they only have four lobes - not a lot of resolution.
