Large Scale Mould Making - the Evolution Answered
I'm so excited, I now have + hours of video to cut and share :)
Finished the split stand
Set the finished plug in the stand and aligned our waterline
Bondo'd stand and plug for a flange line
Applied mold release wax
Sprayed PVA (Poly Vinyl alcohol)
Applied a polyester tooling resin with cabosil (A silica thickener) to serve as the inner mold face (outer shape/surface of final product)
Applied 4 layers of chopped fiber with polyester resin (took about an hour and we're still a tad bit high - even with good ventilation)
Mind you the resin is catalyzed with MEK-P (Methyl Ethyl Keytone Peroxide -- some call it rocket fuel. It will eat the flesh off the bone and then eat the bone.
Why am I so excited? Because we finished today and the catalyzed resin was COOK-ING. "Too hot to touch" is about 180 for the average meat human. It's well above too hot to touch - in fact, the radiant heat is a bit much for most meat peoples. And that's with the prescribed 1% catalyst.
More information coming soon :) It's going to take 8 hours to capture all that video :P
