Hi all, im trying to set up my first forge, i have an oul drum that im looking to hammer down like a calypso steel drum, i have a short length of tent stove pipe to use as an ash chute and cut a slot in it to angle air up into the coal base, and for the air supply, i have some 1 to 1.5 inch inner diameter sump pump hose and i was wondering if anyone knew whart else i could do with the materials, i have a 16 inch truck wheel rim but cannot find any non gav or ABS plastic flanges and pipes, any advice??
