What thickness sheet metal were you thinking of using?Because i would use a minimum of about 2-2.5mm thickness and that would take a long time to shape and shape it good so it's not an oval.What diametre pipe were you planning on making?...
I agree why dont you just buy the god damn tube coz you'll end up with burn-threw anyways(excess metal on the inside of your bodgy job home-made tube)
anyways fact: you could use 1.2mm sheet and still achieve a pressure rating of 1000psi+ considering you can weld properly
