You need to just do some picture reading, here is my description. 55 gallon barrel with 1 inch female fitting brazed (not welded unless you have a wire feed) the you put in a 12 dollar electric heating element. Get a home depo or lowes paint mixer (9.99) and find a way to run it without any sparks. Old enclosed drill, air gun, brushless motor or use pump mixer. You cannot use a pump to mix your methaloxide though, its has to be done mechanically instead of a pump.

Put a lid on the barrel to reduce your fumage smelling.
