I hope this finds you safe and well.
My traveling forge (the one in the photos) is made from a 12" piece
of well casing that a friend got me and welded on the 2" black pipe
that goes into the side at an angle designed to create a vortex
inside the forge.
The gas is delivered inside the 2" pipe using a 1/4 nipple with a cap
that has a 1/16th inch hole in it. This has a 90 degree elbow that
protrudes from the bottom of the 2" pipe. A regulator is mounted
between the supply and the 1/4 pipe to regulate the flow.
The inside is lined with "KAO Wool" and has a single fire brick as a
floor. There's also a refractory coating, which I would leave off
next time I re-line it, since traveling is tough on the refractory
coating, and it's not *absolutely* necessary.
This is the type of forge on which I learned. The blower is a
hairdryer, and the forge heats up to about 2500 degrees when I have
it properly closed off with fire brick.
If you google "Pipe forge" you'll get a lot of information.
Basically, there are two types of pipe forges: Blown (air is forced
into the forge like this one) and Venturi which uses the pressure of
the gas to draw more air into the burner. My larger shop forge is a
venturi type. It's quieter but it heats up to only about 2300 degrees
for normal use. I've forge welded with it just to see if I could, but
it doesn't get that hot very quickly. It's larger, so I don't take
it with me.
They're both great to use and fairly simple to make. If you don't see
enough info after your google search, let me know, I'd be glad to
tell you more when I have more time.
P.S. Using several firebricks front and back you can configure
openings for passing longer work through the forge. Also, were I to
do it again, I'd drill the hole for gas delivery into the 2" pipe on
the FRONT, not on the bottom, so it's easier to protect the
regulator, and it's easier to read same while in use.
