i have no idea what the tank weighed with no motor on it, but i'd guess around 200+ Lbs. the firebox is a bit over 160 Lbs.the RF BP is about 50 Lbs...so that is already 400 Lbs. then add the legs, the wheels, the racks, the stack, my 11Lb spool of mig wire, FB basket, etc. should be a fair amount over 500 Lbs. this actually surprises me, i'd have guessed an end result over 600 Lbs, but maybe it's not that much?timsatx wrote:I am looking at building one too. How much did that bottle weigh? When I do mine I will have to figure out how to lift it.
