So the face of the anvil is tilted away from me? Isn't the whole idea to have it flat?
Glenn I will give the router approach a go so long as no one has a better suggestion, a handsaw probably wouldn't cut it (ba doom tish) this thing resisted being cut by my little chainsaw (the black mark in the img) though I admit it needs sharpening.
I have checked and the few cm I will take off levelling it out should put my anvil at the right height, though I plan on replacing it somewhere in the future. The anvil I have is small and the horn is broken off but it was free (you can see its base in the top right of the 2nd img).
