Made some more progress with the frame this weekend. My support rods are installed - all except one as I was short by one machine screw. I picked up a Rockler bearing and was able to modify and mount it. Found something out to share - There are 8 plastic feet on the bottom of the bearing, I removed 4 of them to drill the holes through to mount it to the frame and left 4 feet still attached. Keeping in mind that this is aluminum and will bend, when I mounted the bearing to the frame, I added two flat washers between the bearing and the frame to match the spacing of the feet. This kept the bearing level as I tightened it to the frame.
I started cutting the dome ring for the C&D dome. Once that is complete (along with some clean up on the inside dome), I'll be able to mount the dome to the frame.
