Lol, portable so we can put it up when not in the shop not so we can move around. But yes we have that pressure in MANY locations where we're building. I am in the US and this is in my workplace so you can understand why I don't want to say too much, there's just a lot of time to kill on night shift... Ok I'll do some more research and see what we come up with, we have plenty of raw materials to work with and it's already hot as balls so we're going to get this forge going to see what we can do!

We are building a small forge in our shop. We have 40psi natural gas fed by a 1" line tapped off of a 12" main, volume shouldn't be an issue, and want a Venturi setup so it is portable. Our question is what orifice size do we need and what pressure should we regulate down to. We have 35 and 45 welding tips handy. Anyone have any tips? We were thinking about 2 or 3 2inch ID burners with diffuser plates, so ribbon burners. The forge is 15.5" wide, 18.5" deep, and 12" tall without refractory or bricks. We'll have 4 bricks laid flat in the bottom, then bricks on each side and refractory in the top giving us ~972 cubic inches (18"x9"x6"). Any help would be appreciated!
