Pressure cooker for vacuum chamber (casting)

[Richard Bowman]

I am looking for a cheap pressure cooker, old fashion cast aluminum style, to fashion into a vacuum chamber for casting rubber parts. If you have an old one lying around that you would be willing to sacrifice, it will be put to good use.

I have a stainless stovetop model you could look at when you return my car jack. 

It's not the old fashioned type with the valve on top. 

I prefer the newer electronic model with the built in timer so no longer use the stovetop model.
