the only structural chassis steel that i would suggest is 1020 D.O.M (or drawn over mandrel) with a min. of 1/8" wall, D.O.M. is a special technique that renders it seamless and stable. if it is compleatly impossible to find the rite stuff i would recommend not proceding all. but 4 being the massocist for pain and bodily injury, i would say atleast find a good seamless pipe and TURTURE TEST it, tie it into a pretzille with a 20lb sledge then hammer it flat, then untie it and hammer it round again. then if it has no signs of stress cracks' or fractures, would i think about using that type. with that i would then cross my fingers @ any speed over 30m.p.h., but I'm just a dirty old biker with no education that used the right steel for every chop I've ever done
