can it be done
is it possible to some how make a perfect cylindrical cut in the silicone to accept an insert many thanks there has to be a way cheers
I once made a tool to cut a cylinderical hole in foam rubber. I'm not sure of the material of the body 2 you reference but what I did was this:
I cut a length of steel electrical conduit. In this case it was about 2" diameter. Then I used a moto-tool, you know like a Dremel or such, with a drum shaped grinding bit to grind a sharp edge on the conduit.
It requires patience and care and some dexterity to keep the edge nice and even with the angle of the cut. I ground from the inside so as to keep the exact outside diameter of the conduit. Then just hold the tool in place and twist it while applying a bit of pressure.
Worked perfect for me.
Hope this is useful.

This is another manufacturer and a different mod, but Midiman's Bianca was made without either core for the movie, and subsequently modded by Matt with cores. At some point, material must have been removed to do this mod, how this was done could be relevant to your operation if anyone knows.

You would not want cutting 'teeth' on the tool because of course it would shred the silicone and make horrific tears. You want a very smooth and razor sharp edge. To better illustrate what I described I modeled and rendered this...
You would have to grind very carefully and slowly to get a razor edge.
If there is no opening now, and yet the doll has been cored (is that what you mean by void?) you would have to find the location by feel, or make a tiny hole and use a wire probe.
A better description of what you have, even some photos would help in finding solutions to the problem
In my case I had planned to use thin wall tubing, "razor" sharpened on one end. However, in my design and all of the other "tools" mentioned here one important step seems to have been left unanswered: Silicone is not rock, earth or glacial ice. It is not brittle, it is extremely flexible and will not simply snap off at the end. So, just how does one manage to remove the "core" after one has bored it?
