anyone know of any outlet for pressure cooker parts? I actually need a generic (any style) wobbler type weight for the top of the pot. I am making a root beer brewer for a halloween party, and have an old gatorade orange drink dispenser with a screw-on lid. I want to put mix, water & dry ice in, then seal to pressurize it (safely) to give realy good fizz. (I did it last year in open (new) garbage can and it was not very fizzy.)
So I want to install a small pipe/nipple coming out top of drink dispenser unit, hopefully nearly same size as nipple that would have come out of top of pressure cooker, but I need a weight to "wobble" on top of said pipe/nipple to regulate pressure. I figured if there are replacement ones available cheap then it would save me from making that part from scratch (not sure what kind of profile to put inside "hole" to prompt the wobble)
Any other ideas from this remarably pragmatic and creative group would certainly be considered.
