Propane and stock removal tools

[ApprenticeMan]

See with propane forges and coal forges(as coal is going up too), there is that huge difference of(for this example a hand crank blower, or air grate flapper, take your pick, mine is hand crank so that's what i'll use for the example), when you stop cranking and turn to forge, the forge stops burning fuel at a high heat rate. There should be some way to make something for a propane forge that makes it so that when you step up to the forge to heat something up, you can put your foot on a pedal, which adds more propen and/or air , and when you step away that pedal is not pressed decreasing the amount of propand and/or air. I do not know much about propane forges and burners, but I guarentee there has to be a simple way to fix the problem of the forge burning super hot at your back and waisting all that fuel while you are forgeing.

Take a look at gas savers for OA torches; unfortunately a lot of the heat transfer to the work in the forge is from the lining and so letting that cool off can make a big difference in how fast your cycle time is.

Ron Reil showed an idle circut for his forge. Should be on the Abana Site. he T'd off the main line through a needle valve and then T'd back into the main line. He had a ball valve that this circut went around. He would throw open the ball valve when he wanted to forge. when the ball valve was closed a small amount of gas went around through the needle valve and kept a small flame lit.

I have found that if I shut off the propane and then get back to it while there is still red inside, the forge will generally relight. I also decided that I should just keep feeding stock into the forge so that something else is heating whilst I'm beating.

Mills, I do the same thing. I have 2 burners on my forge, so I always try to have SOMETHING under each burner while I work Even if it's just a piece of scrap stock for practicing a technique on. In terms of slowing doen fuel consumption, I turn down the regulator and decrease pressure if I don't need to extra heat. And I have also found that the forge will relight if the chamber is still hot enough.

Here's a copy of the idle/full piping schematic for propane burners. I use this same set up on my two burner forge.
