Building a traverser / transfer table

[Trolleyfan]

To get power to multiple tracks on the transfer table/traverser you could use ribbon cable similar to that used to hook the harddrive in your computer to the mother board (IDE cable), just make sure it's the easily flexed type and not the stiffer type. You could also use multi-conductor cable if you just let it hang down through the benchwork in a loop with both ends held tightly in a cable clamp. Just an idea.
