Looks like you basically have the same set up I use. Glad you posted some pics because I just moved and I haven't been able to dig mine out of the garage yet.

Hold on guys, so you do and can preasurize the RTV?
Do you do this after mixing, like the vacuum way? or after mold is poured?
This is a question in our Ask G&J going to press


I mix and pour my mold and stick it in the pressure pot overnight. Works fine.

my set up. I made my gauge removable, but I can't remember why, maybe in case I have more pots someday. I'd like to make a base to set it sideways.

Gee, they're so nice looking when they are new. I'm not even sure what colour my pot is anymore.

I been keeping it pretty neat since I keep moving it around and I'm not doing big parts. Most of the mess is on a plastic sheet I spread on the dining room table.

Also notice the little hot plate in the background of the first pic, helps cure time in the winter since the garage gets cold.

I was wondering about the hot plate. I balance mine on my mattel vac-form to heat up the plastic sheet before vac-forming. I will have to build a real vac-former one of these days!
