Hello from France dear friends ! :)

I want to make my own 65cm high silicone articulated statues.

I prototyped a brass "skeleto-mechanical" hand for the poses (and I will make the whole skeleton) and I am quite satisfied even if there is still a little work to do to place the wrist joint.

A second version will be started with another idea for the "metacarpian thumb" articulation

I would like to find help regarding the coating that will be brushed on the skeleton before putting it in a mold and then pouring the silicone, because I think that without coating, the silicone skin could be pierced by repeated handling . . .

Has anyone already had to do this? Or ideas would be welcome please!

NOTE: I'm back from my "cavetelier" (cellar workshop) and I tested several "rubbery" materials (but not directly on the mechanical hand!!!! Too afraid of damaging it), flexible and semi-liquid/pasty, by making mixtures and seeing if one of them can be flexible and not "break" by bending the "test joint". . .

An acquaintance showed me this test that she had done a while ago and she told me that she had not found a solution and therefore abandoned her project . . .

QUESTION: does anyone accept commissions for silicone moldings and silicone castings? I don't have the time and the skills, even if I learned a lot about silicones by experimenting with a few small things myself. . . But for big serious things, it would be wiser to have these steps done by someone who is talented @^;^@
 
Maybe some info in this thread will be useful:

 
Beautiful piece of mech you got there. Maybe you need to create some interior rigid parts, sort of a smaller hand broken down into articulated parts that you can place in the mold with the mech prior to pouring rubber. So that the metal pointy parts don't touch the silicone directly.
Also, reinforcing those silicone finger tips with mesh or similar could help.

I do, but we're in Spain,
