I've been giving homemade anvils a lot of thought lately and after the video posted by Glenn in "What do you need to get started in Blacksmithing?" it got me to thinking what makes an anvil a good one or a awful one? assuming mass placement and the quality of the face (hard, soft, rough, or smooth) are the key factors I've got a 5"x5"x1' piece of square stock (very heavy duty stuff used to make drive shafts for larger electric motors) sinking it vertically into a stump about 6" hardening the end (face to be) i figure it would make a fine anvil even if its basic can you think of any reason this wouldn't work? or how to make this better? I've got very little experience with this. so this is mostly based off logic (which can be quite faulty at times) so any tips or tricks or general knowledge would be greatly appreciated.
