Mini Forge Page
First and foremost
I saw a web page by Ron Reil that had the instructions on how to build a propane forge from an old freon bottle. I liked the idea so I researched it farther and found several other pages with forge building information on them. I then ordered a book called Gas Burners for Forges, Furnaces, and Kilns by Michael Porter. I used a little of the information I got from everywhere and put this forge together.
I will show the steps I used and add some of the things I think I learned, I hope.
Also some of the Burners I've Made

First make sure the is no propane left in the tank, mine was empty and had holes cut with a torch in both ends. So I knew it was empty and safe to work with.
If in doubt, be safe fill tank with water before cutting or grinding on tank.
I started with a propane empty bottle I had several in my junk pile so I used an old used bottle. It had holes burned in the ends so it could not be used for anything else. First I cut the handle off the top using an angle grinder and cutoff wheel, then removed the valve. I needed to draw an eight inch circle on the top to cut out for a door, so I put a pipe plug in the valve hole center punched it and used a string and center punch to make my circle.
I also needed an eight inch circle on the bottom of the tank, the ring on the bottom is eight inches so I just drew a line around it for my circle. Then using an angle grinder and cutoff wheel removed the ring.
I then moved on to cutting the openings in both ends of the tank. Note the whole circle is not removed but a flat is left on both ends. This is to support the six inch wide kiln shelf that will be installed later.
Tank with both ends cut out
These are my burner parts. the burner is a six inc piece of 3/4" black pipe, The accelerator (picture on right) is made using 1/8 x 4 inch heavy black pipe and the tip from a mig welder.
The finished burner and the burner with stainless steel burner flair
Adjusting and testing burner
Legs mounted onto tank, handle and burner mount welded onto tank, ceramic shelf checked for fit
Burner mounted on tank, Old paint burned and then sanded off tank
Tank then painted with heat resistant paint
Koawool added to inside of tank in two layers to insulate the tank , this will be painted later with a reflective coating ITC 100.
Right picture, Forge first one minute burn outside, hard to see the flame but it is there.
No doors yet, but this burn was the first to get the whole thing hot, The white in the
pictures is the lining glowing.
Forge now has doors I made them so they can swing up out of the way. I made the doors from the ends of the cylinder, then covered them with koawool that had been soaked in rigidizer
Forge burning with door open and door closed
This is just a quick look, more and better description to come later.
Small Second Forge
While I was building my first forge I saw a picture of a small forge. I thought I could use one like it for heating my burn sticks.
I build Native American Style Flutes and use burn sticks to make the finger holes
So here is what I came up with not just like the picture I saw, but works
Made from the end of a small air tank and lined with Koawool, I used part of a kiln shelf for the floor.
As you can see I does get hot
