I made an anvil stand for my 275 pound anvil from instructions and plans provided to me by Steve and David Kane at Kane and Sons Blacksmith's Depot in Candler, North Carolina. The stand is constructed of scrap floor trusses, two oak boards, 4 threaded rods, and 8 washers and nuts for the rods.

I have attached a diagram of the design and a photo of the stand with the 275 pound anvil that has been held securely in place for many years in my shop. The same construction was used to make the anvil stands that are in use at the ABS Bladesmithing School at Haywood Community College in North Carolina.
