DIY LED Bat Top joy sticks
Slippyblade:
Randy's right about the vacuum chamber. Mind you, one doesn't need to be expensive. My wife does pewter casting and when setting up her silicon molds we use an oversized tupperware dish from the dollar store and a shop-vac. Cut a hole in the tupper that fits the shop-vac hose. Shove the hose into the hole, slide on O-ring on the hose from the other side and Bob's yer uncle. No bubbles in the mold.

I like the bubbles, too.

well if someone wants to loan me their degassing chamber, i'd be willing to do a run. Or, if you have a little write up on how to make a home-made one, i could give it a shot. There are some nice pro ones on ebay, but i'm not in the mood to spend 200 bucks.. If i went the shop vac method, how long would i need to apply vacuum to the cast? I can't let it go too long otherwise it will begin to harden.
The new molds i cast are just about dry, i'll check them when i go home for lunch. I will also try to be very careful about stirring on my next run. Also, one final thing -- do people like the Happ 4 way competition bat tops, or the regular Happ competition stick? I am currently making molds with the 4 way style (the one in pictures).
I could make a little jig which could could make 6 tops at a time... i'll be back shortly.

I run the shop-vac for about 15 minutes, but it really depends on how good the seal is.
