Check out this amazing wooden skeleton hand project by Ronald Waters. According to the video description, the hand was made using a pattern found online. The hand parts themselves were created with a scroll saw and Dremel rotary tool.
From the video description:
This video is a test of the pull-pull cords for the fingers and the spring tensioned center cords. There is still quite a bit of work to be done before this is complete.
A hole was drilled through the center of each bone in the hand. Center cords run through each finger. These are attached to springs which hold the joints together by compressing them. Cords outside the fingers on the top and bottom act as tendons and control strings.
I'm not sure what the final product will be, but I can already tell that I'm going to like it a lot! I am looking forward to the promised updates.
