Turntable Drive

Posted by yesterdaysradio1 on Saturday, June 2, 2007 6:12 AM

I am curious why the Geneva drive is not used for turntables. There is a slight hesitation every 15 degrees, but I am willing to accept it. The Geneva drive is so precise that it is used for film transport. It is also very inexpensive. Has any one had any trouble with this type of indexing?

The Atlas Turntable uses this kind of indexing.

The Atlas is a small turntable. I will have a 16 inch bridge with 15 degree spacing. I think Atlas components are plastic injected. I machined polycarb, acrylic, and brass. This will give me precision location. Has anyone done this? What trouble could I expect?
