Huge warhammer in Blacksmithing, General Discussion Posted January 22, 2008 You could buy the #110 anvil from Harbor freight for ~$70, take a torch or other cutting tool and cut out the shape you want, then drill a huge hole in it with a drill press. Then get a solid 1inchish bar the length you want and weld it into the hole. You could probably get a decent looking #50 steel hammer out of that anvil. Personally I would get a block of wood and put some heavy steel plating on it and weld them on somehow, then use that solid bar and mount it in somehow. You could get the same size as the solid steel anvil, but it'd be like 10-20lbs.
