marino and i thought so,too.
but the 4140 tubes seem to be pre-treated for welding when theyre made,so the tubes broke in the bender.after calculating and recherche i figured out we´ll have to "soft glow" them,then weld and finally harden and temper them.
now it works,theres some proto stuff on its way to me.
my fork will have 405x45,mag mounts behind fork legs.we´ll see...
