picture above is of a small gas forge
I built using a 2 pound Maxwell House coffee can for the forge
It is lined with 2 inches of 8# Durablanket that has been coated with
QF-180. I used some 1" x 1/8" flat bar to make the legs for the
forge body, but you can use whatever you have on hand in your shop. The
legs are fasten to the forge body using 10-32 machine screws.
The burner used in this forge is the new Micro Side Arm
that I recently designed. I make a lot of candle holders and this
little forge is great to heat up candle pans and dish them out, I would
say that the largest stock that you could effectively heat up to
forging temperatures would be 3/8" round stock. The original idea
for building this forge
Donnie Fulwood's web site that had drawings of a the Bean Can Forge
by Ed Halligan.
The picture above
is of the coffee can forge with
the micro side arm burner running at 25 psi after about 15 minutes.
of the forge, the temperature was
2000 º F. I measured the temperature inside the forge using an Omega HH300 Series Digital Thermometer. Building the coffee can forges, I have used a micro tube burner and I have also used the Bernz O Matic model # JTH7 torch like the one used in the mini forge for the burner. The outcome of both were a great success. I used a conduit hub to hold the burner assembly in place in the first coffee can forge that I built. But now I am just using a couple of conduit lock rings and pipe nipple of the appropriate length and diameter for the burner that I am making. It is the same set up that I used for the burner holder on the simple gas forge.
Thermadyne has recently introduce a new line of torchs called Turbo Torch that show a lot of promise as a good source for a ready to go burner for the coffee can forges. I will be getting some of them in the future and trying them out, I will post the information about the turbo torches as I test them.
November 28, 2008: The picture above is of a new Coffee Can Forge
that I just finished building for a customer. It has an
adjustable stock rest that was made from 1/4" round stock and two
pieces of 1/8" pipe. The burner holder was made for a 3/4" pipe
nipple and was installed into the forge body using (2) 3/4" conduit
locking rings and (2) 3/4" x 1" reducing washer to help strengthen the
burner holder. I also drilled (3) 3/8" holes in the burner holder
to help draw in some secondary air for the burner.
pictures above are of the
Turbo Torch kit LP-1 LP CONTRACTORS KIT and of the coffee can
forge running with the T-6 tip.
Update November 31, 2008: I recently purchased a Turbo Torch outfit LP-1 LP CONTRACTORS KIT which cost around $175.00. I know that may sound like a lot of money, but the kit includes two tips: a T-4 and T-6 that are stainless steel, a LP regulator with POL and a 12 foot LP hose. So you do not need to buy anything else to get you going. This outfit is set up to run off a 20# Propane cylinder. I put the smaller tip (the T-4) in a coffee can forge and it got it up to 2100 º F.n Then, I put the T-6 tip on it and put it in the coffee can forge and it went up to 2400 º F + in no time flat. I am going to purchase a T-5 five tip and see how it works out, because I think that the T-6 is a little too big for the coffee can forge and the T-4 is a little too small. I will probably be building a larger forge in the future for the T-6. I must say that this is really an impressive torch outfit.
Below, You will find e-mails which include feedback from various blacksmiths and Bladesmiths who have built a Coffee Can Forge.
