I have an anvil that has been well used, and I believe missed somewhat. It has a very low spot in what should be the flat working area. I need information as to how to go about repairing this and the edges. I don't have funds to take it to a machinist to have it surfaced. I'm also trying to build tongs to work with as I can not afford to just go buy them. Please any and all help would be greatly. I'm a old disabled veteran that could use any help and or information. Thank you for your your time.
