Odd that you would mention that as it sounds like something I might do.
Working on a low pressure hobby class boiler made from an old propane tank, and building a slam valve head for a 2 cylinder compressor I have.
On the more serious side, I have the heat issue with both the controlled and the motor right now. I am going to try the 5 amp foot control I found. But I wonder if it is a missprint and they mean .5 amp.
