Background info: I have a Swedish anvil that has a nominal 1" hardy. It's actually between 7/8's and an inch and not perfectly square. The anvil face is HARD. It had been abused. We tried to smooth it out by hand. No joy. We tried to mill it. No joy. I ended up taking it to a machine shop and they used a head milling machine. And they said, "That dude's hard.".
I also have a JHM Competitor that has a 1 1/4" hardy. I'd like to be able to use the same hardy in each anvil.
Prolbem: Is it practical expand the 1" to 1 1/4"? If yes, what would be the best way to do so? Presumably that may create an issue with weakening the tail.
If I can't expand it to 1 1/4" can I at least square it up and get it to a real 1"? If yes, what would be the best way to do so?
