Thanks Frosty-
Yeh, he calls for brazed joints. I used solder because thats what I had...
Mike's tubes are 12" long with about 4" dedicated to slotting for air intake, leaving about 6" for mixing. I said 14" because thats how much sticks above the forge including jets, valves etc. I would like to reduce that for safety's sake. I'm thinking I will go with "bell" type air intakes. Do you know of any good plans?
What do you think of ITC-100?
Being the cheep **** I am, I'm always looking to get 10 outa 5.
Given that I've only run the forge about a dozen times mostly between 5-10 PSI, I bet if I turn it up, I'll get to weld heat. I just seams to me, at some point the air-fuel mixing with be reduced because of the small tubes. On the last forge I built, paturned after a ferriors forge, I made a (I forget what it called) ring inside the tube to cause turbulence to aid mixing.
