i like the blown forge so far. it's pretty simple, no mig tips, flared ends or any of that. just pipe, pipe bushings, cheap regulator/hose, free hair dryer from the goodwill bag.... screw it all together and light it. my regulator can go from lean (near blowout) to super rich (big yellow flames coming out both ends of the brick stack) , but i have only had my blower set on low so far. I have the zoot-capri 3-speed pink blower so i need to push it up to 2 or 3 and crank up the gas and see what it will do.
I'm a little concerned that it will be a gas hog, but i'm still on my first 20 lb tank, so we'll see.
if you can plumb in NG that would be very convenient.
