Geneva Wheel, Help Required

Hi Everybody,

 

As a departure from designing mould tools I have to design a fixture with a rotary table for de-gating plastic injected parts.

 

The question is. What is the best/recommended way to rotate and index the table every 45 degrees?

 

My first thought was a Geneva Wheel arrangement driven by a pneumatic cylinder. What do you think? Good/Bad?

Any input gratefully received.
