Alright, so I now have the pants detail and all of the parts seams fixed where the parts will fit back together nicely once cast. This completes the last of the sculpting process and I am now ready to mold the parts.
In the past, I used a "wet" pottery clay to lay out my mold beds. This time, I have chosen to use a white Sculpey clay instead. This solves my moisture problem, as the wet clay has caused nagging condensation on my parts in past molds. And, Sculpey doesn't dry out very fast, so I had a lot of time to work on the mold beds and do them right.
Basically, a mold bed is where you embed the part up to the place where you want to put the mold seam. You add registration marks and channels for air chutes (to aid in air release). This means you are only molding 1/2 of the mold the first day that you pour rubber.
The second day, you remove the Sculpey clay, clean-up any Scupley reside and grease the dried rubber with Vaseline. This prevents the second day of rubber from sticking to the previous rubber and allows the two parts to effortlessly pull apart after the second day rubber has hardened. And voila! a nice 2 part mold.
*On a bummer note, I gave myself Carpal Tunnel symptoms during this phase of the project. I purchased a big box of "old" Sculpey. It was too hard to use, so I got some clay softener to rejuvenate the clay. So imagine a long night of kneading tough clay to try and rescue it, and in the end, ruining my right hand from all of the squeezing. It's a little better now. I've finished this project and am resting my hand before starting the next one. Note to self... Next time, just buy new clay and throw away the old stuff. Heh.
