In a quest to melt Iron, I figured I would need a real big fire....luckey guess. I have goten a few inquireies as to what i did. simply its a length of 1-1/2"pipe with a reducer to 1" a short nipple & a homeade flair from a pc of 1-1/2" tail pipe. a kitty litter bucket for a throttle box & some 1-1/2" plastic pool pump hose. Oh yea... the propane tank,regulator ($19 at home depot) hose & a barbed brass hose to hose conector for the injector. 15min to make the flair & the rest is duct taped into position. my blower is a small dirt devil vac I picked up at a 2nd hand store for less than $10 bucks
