Then Saturday it was time to go over the Rockler bearing and replace the ball bearings. I more or less went with the video here to do this, and was done in about an hour. Here you see the bearing disassembled:
Here's my dome ring catching the bearings as I let them out.
Per the video, I made sure to mark the starting point of the plug screw so I could line it up exactly when I was done:
After that, I needed to cut the dome ring itself. The owner of the makerspace showed me a neat Dremel tool (shown below) where I made a mark at the center, drilled a hole, and used it as a guide to cut a perfect circle. Came out nice.
Sunday was quiet, mostly drilling holes between the dome ring (note the hole) and the MDF supports, as well as the bearing itself (I should have drilled before I replaced the bearing; I'll probably empty it out here shortly just to get rid of any stray metal filings). I basically followed this tutorial for the drilling, even if the holes didn't match up I'm pretty close to the mark.
Here you can see the inside with the bearing mounted inside the dome ring. I'll need to get some nuts for spacers so the ring will actually turn, but that's no big. And when my holoprojectors come and I verify the fit, I'll be able to glue the MDF ring into the inside of the dome and secure everything, and still have the ability to get in there and do maintenance.
So. With only one month down, I've got the dome nearly done: just need to get the logic display frames cleaned up and painted, finish building the light systems, cut out some milk jugs for the diffusers on the logic displays, and glue on all the outside bits. Basically, I'm waiting on parts and then a flurry of soldering (I'm as far as I can get on that right now without a primary smoke test). I've got a frame on the way in February, legs in March, all kinds of body bits printed and ready, and I'm even starting to glance a little at the intricacies of getting this sucker moving. This is coming along fast. And it is fun.
