Propane Forge in Action....w/ Pics
I wanted to post a few pictures of the propane forge in action. It seems to work pretty well. It takes probably about 10 minutes to reach full heat and by then the cement is glowing orange. I run the propane regulator at about 12psi to heat it up, then drop it down to about 8-10psi.
If I were to do it over again, there are a few things I would change, and will most likely incorporate into the larger forge I will be building soon:
1. I would start off with a larger diameter pipe so I could use a thicker refractory cement shell to better insulate it. Right now I've got about 1.25" of cement and a 1/4" thick ceramic fiber blanket and I think I lose too much heat through the body of the forge.
2. I would have two burners to more evenly heat the forge. Right now it's about 13" long inside and there's about 4" right under the burner where stuff will heat up very quickly; outside of that zone it takes longer. Plus I have to put pieces in at least 6"-8" to reach the "hot spot" so having two burners would create a hotter zone closer to the door.
I would use the refractory cement again......I just don't see how the kao-wool type blankets would hold up to hot, sharp pieces of steel being jabbed into the forge. Anyhow, here are some pictures of her in action, along with a picture of the anvil stand I made. David
