Had planned on maybe using some ball bearing coupling on the top and I guess I could do the same for the bottom, then just have the motor turning the shaft from the bottom where the shaft extends beyond the bottom supporting ball bearing. Now the question is what type of motor, and gearing, and controller, and potentiometer, (etc) do I need to get this puppy rolling... | |

I think I could get by with as small as 3/8" shaft of aluminium tube that's embedded into my wooden shaft (equilateral triangle 3 5/64" wide, 30 inches tall.). The triangular wooden shaft has 3 vertical tube-light fixtures mounted to it, and the shaft needs to rotate 360 degrees then oscillate back so that each light exposes the vertical polycarbonate aquarium tubes surrounding the shaft. Here's a quick google sketchup: goo.gl/fZykD | |
