Thank you. I?ll grab a torch and try on the old beat up one first.
Yes, with steel you want to dunk in water or motor oil while red hot. That will heat treat but be brittle until you anneal (heat up until bluish, can?t remember if you dunk again or let air cool...).
Either way I?ve never tried it with aluminum. I?d hate to snap it off first ride after finding the sweet spot!
