I make progress the hard way. The hard way is the way you take when you do everything wrong, which provides lots of interesting opportunities to learn... which way not to do it.
Strangely enough, there seem to be more wrong ways than right ways.
Finished splitting the arm/hand at lunch. The split is nice, and the two halves fit nicely into the mother mold. However, while the mold is plenty thick at the fingers, it is too thing at the arm. And, because the hand is in a difficult semi-closed position, the two halves really don't want to mesh together.
So I'm going to glue the rubber parts into the mother mold, probably using a polyurethane rubber (since that stuff grips so amazingly well).
I think, as a backup plan, I'm also going to make another stab at a plaster mold... so tomorrow at lunch I zip out and pick up another 100lbs of hydrostone. I'm betting that my wonderful, special liquid sculpy release will work for this. Of course, this means another hour or two of setting up the clay barrier, carefully modeling the difficult undercut area in the grip of the hand.
Anyway, the slow and difficult progress in my mold-making skills has been frustrating. I sometimes wonder if I'll EVER get it down right.
Oooh, and I need to order mold release now, too. Heck, I would make a solid rubber mold instead of plaster (rubber is SO much more durable), but it takes something like five gallons for this large mold. Way too spendy.
