One idea already referred here, trying to develop a rocket stove forge... :| 

I think that could be achieved ....Somehow ?

Cool idea, but the heat req would be difficult with a rocket stove, maybe using coke - turn the J tube upside down - put a fan into what was the riser/down draft! - an opening in the elbow that you put your work into? how do you get to forge temp?

You can actually just about achieve forge temps at the bottom of a riser using wood as fuel (larch is good)....some added forced air maybe?

How about adjustable compressed air thru very hot pre heated pipework in the fire box - into the coals, maybe this would go into meltdown - catch fire :!:

Could you use a stove fan to foce air in
I think they work by having a diferent temp on either side and creating a charge in the "batttery" .that turns a small motor and fan.

Using the fan would keep the forge self contained and keep it off grid ready

An impeller in the flue that drives a pump on the outside like a turbo does on a car?
