Now, these puppeis aren't cheap. but they would definately do the job. They are 17 RPM and reversible 12VDC. You could easily build a 12volt power supply and using SPST switches, controlled by a master DPDT switch, you could even have a decent control system. Using a 4" - 6" diameter PVC pipe would do for the "roller" you'd just need to fab a "yoke" to hold each end of the pipe in place, then connect the motor shaft to a through shaft to provide the rotation. I could sketch something if you think this is inside your budget restraints. . |
If I were to take this route I'd go with a polarity reversing momentary on switch. I can point you towards a link, I could only find one good place to get 'em, though let me know if you find more. It has 10 guage leads on it too. Polarity reversing controls motor direction and momentary on is so nothing ever gets stuck on, which will burn out a motor (important for projector
douser project which I did.) The tricky but would be spiking the height. It might be easiest to just eye-ball everything, or have reference marks along the walls.
