My favorite crowbar / wrecking bar is one that came with a house that I bought.
My plan is to grind off the vestiges of the weld, heat to a cherry red / straw color w/ a torch and hammer it to get the taper needed for a claw. I think I want to let it air cool and grind in the "V" for the nail puller on the claw and blend the outer edges of the new claw. Next heat to cherry red and then??? quench in water? quench in oil? stick the claw end into sand or kitty litter and allow to cool? air cool? quench and then temper?
I have a torch set, hammers, I-beam drop for an anvil, non-contact digital thermometer (up to 500 F, I think) & a contact thermometer (I don't remember the range - was used to test for plugged catalytic converters, higher than the non-contact one).
Your thoughts and suggestions?
