i am making an anvil myself, and am welding mine together, i don't have access to anything other than 2 inch plate. the top plate and yoke are together by way of flux core. i will mount those on another plate for the base, and am searching for horn material, this is my first attempt, it is cheap and very substantial. i have made the top plate over size to accomodate some spoon patterns. i hope to have a longer than usual horn to shape some decorative pieces. this may not be the ideal way to make your own anvil but it seems to be working so far, i will post some pictures when the job is done.
