Another batch of parts finished for the telescope. I have decided to just buy a saddle and dovetail kit from ADM, I dont want to mess with that.

Needed a piece of aluminum rod for the bearing spacer/axle. Couldn't find anything but I did have a piece of titanium, close enough...

Making the spud that the base rotates around. I used some 17-4 TGP stainless I had left over from an old job years ago. Found an insert that would actually break chips with this stuff which just created tiny super hot little chips flying everywhere. Ouch!

I am using a large ball thrust bearing for support and a taper bearing on top of that. The spud ties it all together and also serves as what the fine adjust presses against. I single pointed 5/8-18 threads for a nylok to tighten up the bearings.

This piece is the fine adjustment arm, two Vlier fixture screws will push on either side and allow it to move around it's axis. It is slit down the middle to clamp on the spud and can be loosened for rough alignment.

Everything ready for anodizing:
