This is my simple attempt at building a slip ring....hope it works!!??
Used copper pipe for the rings, one wire will get soldered to the inside of each ring and exit out the slot in the center post. Originally I was only going to use one contact bar/finger on each ring, the new idea has two points of contact on each ring which should work better and the tension on the rings can be adjusted by simply bending the brass contactor arms closer together if needed.

The center post will be mounted directly to the bottom of the body floor and rotate with the house, the stationary contact finger assembly is mounted to the center track frame. Each track drive motor will be connected to the brass leads on the assembly. Really hope this works!!
Not sure how long the copper will last against the brass fingers, and I don't really like the idea of two different metals being used on this but the copper pipe was the easiest way to build it and would be easy to replace if it wears out to fast
