what metal rating for steel to heat treat?

would like to have a go at turning and heat treating the axles

would a stand high tensile steel do? 12mm round bar to turn the axles?

i finding metel turning very therapeutic

High tensile m8 more than man enough fibre glass will snap before the Bolt

thnks arther

EBay 161214378076 you need to measure the whith of the wheel and mounting point of the undercarriage you want the unthread bit in the wheel

Richard, just buy high tensile bolts, and turn the axles from them, metal turning therapeutic eh? Not when you do it for a job,

brought the m8 bolts

thanks all
