Sorry, not sure where this should go. I am building a 16' (diameter) stage revolve. It will consist of floor mounted wheels upon which the platform will ride. There will be a pivot at the center to keep the platform centered, but is not load bearing. The set is built on top of this platform and may require some household lightbulbs and possibly a fog machine (with DMX cable). My problem is how to run power onto the revolve? I figure running cables under the platform to the center and then up through the pivot (then back through the platform to the devices that need power) is the best and simplest way, however I am concerned about the cables getting too twisted. The revolve may complete multiple rotations in one direction before reversing. Is there any way to solve this? Or should we put a limit on how many revolutions the turntable can make in one direction? Also, a question about motors. We are going to use a permenant magnet DC motor to drive the turntable. Which method is cheaper/easier? Belt driven via the central pivot, belt driven via the circumfrence, or by direct contact with a spinning wheel underneath? The max rotation speed is slow but variable, and precision should be within 5 - 10 degrees max. Any suggestions?
