R5's dome rotation upgrade 1.5

Had no free time the other weekend, so I had to wait till Monday back at work.

Due to more limited time, I was only able to work on clearance hole clearance & using my dremel, to grind down the washers that were overhanging the bearing inner diameter.

This is just to make sure that the dome motor wheel has a flat surface.

This upgrade work involves a lot of multi-mini-projects lol. The electric upgrade, dome work, rotation/position of the lazy susan & next, the actual dome motor location and fixing.

I had thought about moving the motor to the front area of the body, so the wheel was at the top. But as I had already cut out an area, years ago in the build, for this position, I decided that here was just as good as anywhere else.

Next was how to mount it.....

I have a rear door stop on one of the vertical body struts, and it's in just the right position to mount the new motor spacer block. It will replace the original door stop at the same time. So I had to make up a new bracket for the motor/door stop, much more sturdier than the last bracket.
There was some thought in how to attach the bracket to the body frame, once the motor was attached to it, which prevented fixing it on afterwards.....lol, I don't make things easy for myself do I :D. The aluminium bracket fits to one side of the vertical internal frame, with a countersunk bolt and then a wing nut. This was the only way to secure, which was actually genius, as the wings stopped the nut from turning when the bolt was screwed into place!
Motor & bracket bolted into place.

Powered up the motor and the lazy susan ring spins great.


Update on the new lower dome metal ring to follow......
