Not sure if someone already came up with this idea or not, but I was pleased with the original wiring scheme for supplying track power to the bridge track....
The photos are relatively self explanatory.... I wired the AC hot wire to the center rail using the turntable pivot shaft as the conductor. Both halfs of the the curved rail running around the pit are wired to the common post and then to both outside rails of the gargraves section on the bridge. I installed a plate and shaft clamp initially to better anchor the shaft to the circular drive disc, I had been having an issue of the disc slipping on the shaft.... Then this past week, I decided the metal plate mounted to the disk could become the pick up for the AC hot. I made a long arm that pivots on one side of the table, with an electrical pickup plate near the center and the far end is attached to a tension spring to maintain the electrical connection while the table is turning.
so far this working great, no power interruptions.. The TMCC and Legacy signals are working without issue, no hestitations. Thought I would post some photos.
