I am in the process of making another head mold. This one will be a full size figure from Kenny Croes.
No matter how well the figure comes to me, I always have to do a little bit of prep work to prepare it for the mold.
I will be making a core mold of the jaw on the right. In order to do so, I needed to hollow out the jaw. This will allow for the second half of the mold to fill into the mouth. This will enable the piece to be somewhat hollow, use less chemical and lighten the weight of the mouth. This was done with a rounded rasp and a Dremel.
The next process will be to fill any undercuts, do some light sanding if needed and seal the model. Once that is complete, it is off to constructing a pouring chamber and pouring the new mold.
