We actually had a "hub" manufactured to mesh with the fingers of output, but this was a considerable amount of weight, and if it can be avoided, we're always up for new ideas.

We made ours out of a scrap disk of PVC. One of our sponsors is Precision Plastics. They gave us a box of all types and sizes of scrap a couple years ago. It was just one of the items in the box. It needed a little cleaning up on the lathe but after that it was perfect.
