We are now in the mechanical finishes and the last parts ...

Pointing rings

As mentioned in the presentation, the pointing ring on the RA axis cannot function as is: the locking screw passes through the body of the mount.
This locking is carried out on the preloading nut of the axis bearings.
I machining a new longer nut, serving as a hub for the ring, the tightening will be carried out in a groove provided for this. The pointing ring will be re-drilled and tapped in zero digit.

RA spacer ring

The RA axis bearing has been replaced, but since it is a little higher than the old one, a spacer has been made to wedge the worm gear.
