My ribbon burner forge builds up a lot of scale (too much air, according to what I’ve read here.) So I turn my blower down, and increase the propane. But when I turn the propane up, I get a very bad “cavitation” type sound from the forge. Its not only very unpleasant, but actually kinda scary sounding. Scratching my head to figure out where I went wrong. The forge still works, but can take a little while to heat the steel compared to what I feel it should be doing.
Note: I do not know what pressure my propane is running, the guage is faulty. Even if turned off and bled it still reads 5 or 6 psi.
Has anyone experienced this phenomenon with their forge?
