If you make a stand that fits the base of the anvil pretty tightly it isn't very possible to turn it. I have heard of doing that, but for my 335 lb anvil it just doesn't appeal to me. I like the base for the weight- it doesn't walk around but it isn't bolted so I can easily move it if I have to. The sand also takes all the ring out of the anvil making it nice to work on, and it makes it easy to adjust height- that can be really important if you want to switch anvils on the same stand. I briefly tried a tripod stand that looked to be very similar to the one Hofi posted and that worked very well also, and is more portable. It depends on what you're doing which stand design is best for you. I have heard a number of people say that sand stands don't work well, that the anvil will sink in them, and that they don't solidly support the anvil. This design is very simple, solidly supports the anvil, and prevents it from sinking.
