My anvil came with a heavy duty 1/4" angle iron stand, but it was a bit too low for me and I just didn't really like it much anyways. So I decided to make a better looking stand and raised the anvil up a touch. 2"x6"s are all glued and screwed together, then strapped and wedged. Forged a staple and a hooked threaded rod to tie down the anvil, and laid down some clear silicone prior to bolting it down.
Much better sound, I'm sure the neighbors will appreciate it.
