New taper bearings installed on both axes before being lathered in grease.

A cautionary image about condensation and moisture in the mount. Rust spots on the worm and end bearings. When I got this mount the Polar scope cover was full of condensation water , built up over time I guess.

Interesting that with new Taper bearings a hand tight dec retainer , retaining cone is in the design position with locks lining up, almost a full turn further out . A lot of wear for few rotations but does what is required .

Astro Baby misses the requirement that loosening the retaining set screws for the retainers means a full turn and a half to clear the threads. But too many turns on the DEC and the set screws fall inside the cone and then on the floor. Too few on either and the retainer will bind on the outward thread.
