This is something I pulled together from scrap parts laying around a few years back.  A classic example of make it up as you go along, using nothing but crap that you have laying around!

The forge section is an old split rim off a Toyota Landcruiser.  The base is another rim but could be anything that provides a stable platform.  The air is piped through the column (which is simply a section of pipe), where a plate is welded over the centre of the bottom of the rim, covering the hub and the six stud holes.  


I then welded a plate over the hub hole and blew some small holes through with the plasma cutter.  I had to put some baffles over the stud holes, as turning on the air tended to shoot hot coals into the air!  I also used some mesh to block other holes around the rim to stop coals dropping through.  Finally I cut two sections out so I could heat longer parts without having them roll off.


Finally, I added a couple of sections of pipe to the underside, through which a couple of lengths of pipe can be slipped through and the forge moved whilst hot (if needed).


As I mentioned in the home made tools thread, I made it for annealing and melting aluminium and lead etc.  As such, I use hardwood off-cuts that I get free from a friend who runs a hardwood timber flooring business.  I've tried BBQ heat beads and they can get the job done but produce a lot of ash.  The hardwood leaves coals behind and very little ash.

Here I am making some (rudimentary) tongs - 1. no air, 2. air (perhaps a little much), 3. the tongs taking shape and 4. the aftermath.


Here is a drill coupler that I am annealing - 1. ready to come out of the fire and 2. in the ash bucket waiting to be covered with ash and left to cool slowly.


I have tried a few different methods of air delivery from an old vacuum cleaner, a heater fan off a car and a fan from an industrial theater light.  However, I cannot recall which worked the best.  The vacuum had lots of air but was very noisy and I think the bearing in the heater fan crapped out.  I'll have to fire it up soon and see which I want to use.  I have a half shaft that could do with annealing.
cool setup man . I got an old kenworth brake drum somewhere beside the shed my son asked if he could make a forge with it but its still beside the shed lol .he most probably seen a snake using it as home an left it well alone ..wouldn't the heat from the fire melt the rim if its steel ??? I was always worried if I made one outta a steel rim id stuff it up with the heat I needee an set fire to the bush around my place Thumbsup
I doubt you could get it hot enough to melt. I certainly haven't.
I have a forge I made years ago out of a truck brake drum. The drum never gets a glow on, since the outside layers of coal are coking off and act as an insulator. The real fire is at the centre. I think the steel rim will do fine.
Exactly - all the work is where the air is.
