Thanks, I slowed the rotation and it works. How do I make the cylinder fall back into the slot at the top position as it rotates? Does it have something to do with centrifugal force?

I very much appreciate your help, Larry

Very good. Can you contact me please (see file name.), I am not sure how to describe how I need for this to act. I added to your file but I can't get it to work right. I must be over looking something.

Thank you very much for your work, LEE

Thank you for the answer, here is the file....Larry

How do I make the cylinder stay in side the wheel when it turns? Would like cylinder to roll in the slot as the wheel rotates.

have tried lots of shapes, nothing I have tried has worked.

Thanks, Larry
