Hello, blacksmiths!Thanks for taking time to look at my post. I was recently gifted a small propane forge. It was built by a friend who has passed away. As far as I know, he used it, in the condition it's in, regularly and successfully, for all kinds of small forging projects. I have been trying to troubleshoot what's going on with it. Here's what happens: When I turn on the propane (there is no PSI meter or guage, just an open/close valve) then turn on the gas for the forge and light it, flames at least a foot tall leap from the forge front and back-- and continue on like that (no matter how open the propane or the forge valve is) until I turn it off. I tried closing up with forge with firebrick, so there was a smaller opening, and it just blackened the entire inside of the forge as the flames tried to leap out. Photos of the set up:THE PROPANE: https://mail.google.com/mail/u/0/?ui...&sz=w1335-h472 THE FORGE: https://mail.google.com/mail/u/0/?ui...&sz=w1335-h472THE FLAMES: https://mail.google.com/mail/u/0/?ui...&sz=w1335-h472 -(even after running it a while, no hotter blues appear, and the black gunk builds up.)Does this mean that it's too oxidized? That the forge is too small? Or am I doing something silly? Thanks very much for any thoughts,Rocky
