Hi Steve,
 
I don't know about using a vacuum chamber, but I would like to advise you  
that Bil Baird pioneered casting latex puppets when latex first became  
available. (He called it "gummy" in his design drawings.) Bubbles in the plaster  were 
always an annoying problem. 
 
One trick he used was to hold an electric vibrating back massager  against 
the bowl of wet plaster to get the bubbles to rise to the surface and  pop. He 
would do test castings, and would recast until he got a mold without any  air 
bubbles. I don't know if you have tried this, but your products look  great!

problem.   Darn the bubbles!
