I have always felt that the best option for monster or
skeleton hands are the 4'th Quality Bucky hands for $2.97.
The problem; There is no wrist on these hands so attaching them to a prop is
difficult. This is what I did:
Bucky hands usually need minor work to get them into
useable shape. Remove the finger spring; position the fingers, and
the hand is ready to go. I cut a notch in a piece of 1/2" PVC to
make an attachment for a wrist. A little Liquid Nails does the
trick.
