[TheForge] Fw: Anvil repair

Sat Oct 16 22:13:17 EDT 2010

Yeah, that was the direction I was leaning, I just didn't know if there were
any reliable methods to fill as there are 2 spots where the chipping is
pretty severe, I'd have to grind it to damn near a 1" radius to clean them
up. If I happen to stumble on any machine shops in the area that can flat
surface grind it down maybe 1/16" or so, I might go for that, There is
plenty of plate, so I'm confident it could withstand that little bit of
thinning down without damage. I'm no PW expert, but I seem to remember being
told the plate on them was pretty substantial.

  As you have probably guessed Jason..
I'd respectfully advise gently rounding the chipped edges and grinding a bit
off the high spots.
If you need a crisp, square corner( to encourage stress risers), use a hardy
stake.
Ask 30 smiths how to do something and you are sure to get 29 conflicting
directions.
