I made a coal forge out of an old plow disc, welded 3 legs and a blow tube up center, used a piece of steel with holes drilled in for towyer plate,
find a ferriers store near you, I got 50# bags of coal for $15, hammers from northern tool $7, lowes and the hd have them as well, used welding gloves, used a chunk of reailroad track for anvil, made several knives.
You can also use a drum from a car, bbqpit, hole in the ground, stacked bricks, a hiar dryer, shop vac, radiator fan, window unit...
Youtube is where I got all my ideas.
Look up greenpete from the uk, he makes some of the simplest... good luck and post pics!
biggest lesson I learned is that a lighter accurate hammer works way better than a heavy one.
