Here is my idea of a rotary table drive system. I call it a wobble drive. I have not built one. This only exists in my CAD system. I sent this to Andy years ago. The drive he shows in the previous email in this thread was his answer to mine during an email conversation we had at the time. His would be much easier to build and rebuild. Mine had only sliding surfaces at the tooth interface. The advantage of mine (I think) would be there are more than 20 teeth in contact at all times. I have recently taken some time to modify my design and have rollers on the interface and still have the same amount of contact teeth. I have not animated my new design so this old file is all I have. My mind works rather slow.
