I have an offset wrench for my router such as the ones at the bottom of this page:
The first one I didn't use at all, and the 2nd I used only long enough to find out it's too big. Even with this minimal use tho, the jaws are clearly deformed which makes me think it's made from pretty soft steel.
My thought is to MIG a weld bead along the jaws and then regrind to the correct size.
My question is, would this bead be hard enough to function in this application, or do I need to further harden the whole thing?
If hardening is necessary I'd appreciate a quick how-to, since my memories of this procedure are quite vague.
