Is your cylinder mounted between the two expanders?

Yes, on the side of the pivot opposite the tube pickup, so a closed piston opens the claw. There are also stoppers (screws) in the PVC that align the claw when closed.

What are the claws made of? I made mine out of PVC, but yours seem like flat pieces, how do they pivot?

The "fingers" in the video are 1/4" plywood taped with blue masking tape to prevent splinters. We're working on building new ones from Lexan and using top and bottom fingers on each side, separated by spacers..
