I want to build a system to mover a light in a roughly square/rectangular pattern. Reflector and bulb/socket weighs 5 lbs maybe. Possibly 30" x30" square pattern ? The light will make 3 circuits per hour roughly
Thought about using roller chain on sprockets, and machining a part to use in place of the master link to hang the light from, keep the fixture oriented with 2 bungee cords maybe ? With large sprockets or pulleys I could just use 2, but 4 will be easier to get the pattern I want.
Originally I was thinking about using rope on V belt pulleys but I do not see a simple way to suspend something from the rope in a way that it will run over the pulleys properly.
at the 30x30 square pattern there would be roughly 120" of chain involved, meaning we need to move 360" per hour...will drive with some kind of 120vac gear motor.
