Re: Pinhead Project - UPDATE 2/18/2013 Pg.10 2nd support shell is on
lol, I just got this question a few minutes ago too.
A quick run down is the rubber mold was brushed on and when I remove the sculpt the rubber mold will be very flexible and not hold it's shape. So, I'll hold the rubber mold in it's shape then put this "fiberglass like" shell back on. Wrap a few rubber bands around it and some clamps then it will be ready for casting. If I pour the rubber latex in the mold without the support shell it will bend out of form and not hold the right shape.
