Alot of folks are asking about brake drum forges, so i'm collecting the repeated answers here
mastly in the form of photos of how to do it
A basic coal forge is made up of a few basic parts,
A fire pot,
Which is made of stronger metal and is where the burning coal goes, in a brajke drum forge, this is the job the break drum does.A "tweer" or tuyere,
which is the pipes at the bottom that control the air flow.I don't know the right name, but let's call it the table... it's thinner steel, the firepot it mounted on it
and it holds the coal and such and makes it easier to support the working metal...
Then you need legs
or something to hold is up.Next an air source,
an old hair dryer will do, or a 12v fan out of an old car... If you can adjust the air flow thatch good, whether it's with a electrical speed controller or just something to block the air from moving.A way to connect the air source to the "tweer".
they sell rubber couplers with hose clamps on each end that work, or flexible air tubing and duct tape...it doesn't' get hot this low on the "tweer".Finally you need some kind of grate
to go over the hole where the "tweer" is connected to the fire pot (brake drum) so coaldoes not fall through.. if you can also cover up the holes in the brake drum where the lug adn lug nuts went through, you're even better off.
Here come the pics
In the pic above, notice the rubber coupler so the air source can be hooked up,
and all the rest of the parts are labeled.
A clever addition to this one, is the end cap.. there are all kinds of fancy ways to make the bottom of the pipes so you can open to get ash and such out, but this is the simplest.
The part that does that is called the "ash gate"... it purpose is to hold the air in, until you want to let the ash out... and then go back to holding the air in again...
Here is a link to an instructable for one with no table at all...still works
Another one
Here is a long series of pics that explains an easy one if you can already cut and weld metal..
