I want to build saw maker anvil (I do have a real anvil 100# and several RR tracks but I want to have something in 70 lb range with a lot of face space) I can't find one for sale in my aria SC, GA. Here is my idea. Face is tool steel (or what better?) 6"x12" by 1"+. Under it piece of mild steel 5"x11"x2" and under it another piece of mild steel 4"x10" goes to bottom plate. Walls will be 1/2 steel and all the voids filled with lead (not sure if it's a good idea). All structure will be welded together. How do they ring anyway?
