I have been assembling an anvil from several slabs of mild steel that have been kicking around the workshop. I milled a horn onto one slab and in this video I harden the billet that will be the top of the anvil. The “right” way to do this is to weld a 1/2″ plate of hardened steel onto the anvil, but my experiments show that this steel will harden somewhat so I’m going to try a case hardening compound and quenching in superquench.
The hardest part of this was manipulation the 50 pound slab of red hot steel! Note: my camera makes the steel look significantly hotter than it appeared to my eye.
