Rockler and dome drive installed

Tonight I mounted the Rockler bearing to the frame. After removing all of the plastic inserts, I had to drill 3 holes through the outer ring, equally spaced. I used 3 of the exiting ones as guides. The top ring of the frame has pre-drilled holes that match up to the Rockler, so that was a breeze. I mounted it with 1.5" 10-32 bolts and nuts/washers. Then I took it back off to figure out how to mount the dome to the bearing. It was pretty simple: 3 more bolts stick up thru the inner bearing ring and are held in place with nuts. Then I drilled 3 corresponding holes in the inside of the dome ring, and sit the dome on the bearing. The bolts hold it in place. Some more nuts threaded onto the ends of the bolts provide a height adjustment.

The dome drive was pretty simple too. I had to reverse the mounting piece and fashion a substitute way to anchor the tension spring. Tested it out with a battery and it works great.

Pics to come later.
