Wolverine Claws

OK, here are a couple of scans to help you out (hopefully) since I couldn't find pictures with any good detail 

Like I said before the mounting plate was vacuformed  PETG into the mold (tricky to do, especially on a home built machine/table...probably easier to do over a plaster positive)  The claws are polystyrene insulation carved down into the rough shape, then coated with wood glue (to protect them during the next step) which was coating them in polyester resin

after they dried I sanded them "smooth" and squared off the ends a bit, then held them in place in the vacuformed piece via an elaborate rigging or clay and knowledge of teeter-totter physics. ;)  I filled the VF'd piece with bondo auto body filler so that the claws would "snap" into and out of the hand pieces, and waited for it to dry...i must say that the polyester resin needs to be coated with Vaseline or another release so that it doesn't bond to the bondo, which is the same basic material with some fillers added...anyway after that I took the claws out, cleaned everything up and painted it all, then after that I cut the slits for the Velcro. It is the hook and the loop parts sewn together so that when you wrap it around they uh, "Velcro" together..

Hope that helps you figure it out a little bit better.

Here's a pic of the claws rough shaped in foam, set in a clay sculpture of the "thingy" on a  (bad) hand cast, thought this might help out a little too.
