So i read a thread yesterday on another forum, i will have to look the link up it was on my work computer, that people were making pressure pots out of a paint pot from harbor freight. The thread said about swapping around a couple valves and capping some off and voila! I am pretty new to all the casting stuff so i spent most of the my allowance on PR molds and micas. if i spend 250-300 on a pressure pot i think my wife would stop talking to me (which may not be a bad thing......) anyways the paint pot is 2 1/2 gallons like the ones sold, i am aware of harbor freights quality or lack there of, but i have a half off coupon and it would be 40 dollars to start. Providing i do not blow up the garage, after christmas i plan to buy a good one. any thoughts on the harbor freight one?
