[TheForge] Fw: Anvil repair

About what I figured. The Sway isn't really bad, only about the thickness of
a quarter tail to step at the worst of it. If I can find someone in-town
with the ability to grind the face flat for a reasonable price, I'll
probably go that route as it will clean up the edges a bit and get them
where I'll have a small length where they are semi-square. I like to have a
spot on the face where I can get a nice, clean shoulder with 1/2 on blows,
but it is far from critical. I was mostly just wondering if there was a
reliable way to clean them up that wasn't a huge pain.

You're WAY overthinking this. Get some Lincore 50 wire or SmoothArc
600 rod. Grind out the chips to clean metal. Preheat to 400*. Lay in your
filler. Grind. Let cool. Done.
DOn't worry about sway unless it is really pronounced and is affecting the
work. Dead-flat is not necessary - some say not even wanted.
You can increase the edge readii, too, though I am not a fan of this
approach. Leave as much of the anvil in place as possible, IMO.
