I've re- made my molds ... again :facepalm I cleaned up the first casting to get a nice second mold. I then poured a new master in liquid plastic but on one of them, I must not have put enough mold release and well, I destroyed the mold. Now I've gotta wait til I get more rubber. 
I might try throwing the plastic casting on the vac table and see how they vaccuum form. I'm not sure if I like that plastic though.
Yvonne, what brand of liquid plastic are you using these days?
....hey, I'm trying to make some more progress
... yay!
