Having some issue figuring out what I need for my forge to get better efficiency


Recommended Posts

The attached picture is of my propane tank and the torch I have purchased. The system I am running is a forced air (hair dryer) forge. I have tested it out and it seems to work fine, I just want better efficiency so I can work longer. What I would like to know is what do i need as far as regulators go? Do I need a high pressure reg? Or a low pressure reg? I found a webpage from Don Fogg talking about the setup he recommends, using a high pressure reg at the tank and a low pressure reg with a needle valve and shut off close to the forge. Do I really need the low pressure reg? Or is it a preference thing? I'm almost positive that the torch itself is equipped with a needle valve and shut off so i don't need those. Also a general explanation of high vs low pressure as it relates to propane and forging would be nice as well :) (in lay terms, as some of the resources I have checked went over my head)


Any and all help is appreciated!

just as a bench mark i get about 4-8 hrs of forging out of a 20lb tank just depends on if its all welding, or if im just making a batch of blades.........i have a regulator made for propane with a meter on it so i know what my pressure settings are, its handy. i crank it up to 20 for forge welding, 15 for general purpose clanging and bangin and 5-6 for heat treating. Good Luck.

With my small 1 burner forge, I can keep it at forging temp for upwards of 15 hours, running it at most 5psi. How is your forge insulated? I would guess that is the issue here, not the fittings. The better insulated it is, the better it will run once it gets up to temp. Having a good refractory inside will help considerably. Once hot, my forge will stay hot enough for the air inside to ignite paper for several hours. Better insulation means higher efficiency.

What does your forge look like? It's hard to make recommendations with knowing a bit more. You should look at this thread http://www.bladesmithsforum.com/index.php?showtopic=25573. There is a lot of information about forges and burners there.


Except for a very small forge, like a coffee can or two brick forge, most torches are going to be too small to do the job.

So, just for the record: the fact that it does work still should not be taken as definitive proof that you are not crazy.
