I have an idea for a project where I will be photographing items on a surface that rotates slowly and smoothly.
For the surface I'm thinking of starting off with my Ikea "lazy Susan" since it is fairly large and seems to rotate without any wobble. Or I could purchase from a hardware store the mechanism that makes a "lazy Susan" function then install it between a couple pieces of plywood.
But I need to be able to make the surface rotate extremely slowly. Possibly as slow a 1/4 RPM to 1 RPM. Maybe faster.
I own various power tools such as electric drills and a Dremmel. But I don't believe they work slowly enough.
In an ideal world the motor would have a dial where I could set the rotation speed. The maximum load would be only a couple pounds.
Also, how do I calculate something like gear reduction? I know if I have a motor with a small spindle that I can put something like a pulley on it then run a belt around the surface. Can't I by changing pulley sizes make the surface rotate faster or slower? We probably covered gear reduction in junior high shop class but that was way back in the '50s and I have forgotten most of it.
Where would I find a motor that would do the job? Money is an issue...
Thanks,
Terry
