Well the pics of the mechanical hand build I was working on has been scrapped. After 8 full attempts I was just not happy with the final product, they were clunky, very heavy and just plain ugly. Then I had an epiphany...lol
I decided to use the natural recoil properties of the furniture foam to act as the tendons. The end result was a much lighter and more realistic hand. I have included pics and will post a link later in the week when both hands are complete. Each pic will offer an explanation.

This was the last attempt that I scrapped. It looks like a turtle with 3 hotdogs trying to crawl out of it. The Thing had massive Fingers and this design just didn't allow for it.

New frame was smaller and much lighter aluminum strapping was used.

Frame wrapped in foam not only did it look better but it took half the time.

I sliced open the bottom of the foam fingers and inserted small P.E.X tubing that I ran cable thru. I then resealed the foam over the tubing. I also notched bottom of finger to allow for movement as well as sliced a shallow relief cut on top of finger.

Time for surgery. I cut open top of hand to allow room to feed cables in thru aluminum frame and make finger grabs.


Yes I know it looks like a giant Muppet hand but it will finish out very well when stone effect, paint and airbrushing is done. I will be burning into the foam on the fingers to get the separated effect. I cant add additional weight to the fingers or it may effect the recoil. I will posT another pic of the hand when complete before paint along with a vid to show mobility.
I did find that mobility is not as good as with the full mechanical hand, however I will take the slight loss in movement to a better looking more naturally moving hand.
