So I had the idea of fabbing a standalone hardy socket that will temporarily fasten to either side of my anvil as needed. Im also using a RR track anvil but definitely don't want to go to the trouble of milling the hardy into the anvil. I figure the main purpose the hardy hole serves is to hold whichever tool you're using steady, so if I use flat stock to offset the striking portion of the tool over the anvil face, i should be good... right? I'll be working on it this week, need to make a fullering tool for a new sword project. I'll post pics to follow up on how it turns out!
