Here's my vise setup in the basement. It's mounted on a steel post that is lagged to the floor. I like to work standing up and able to work on a stave from either side.
If the weather's nice, I much prefer to work outside in good sunlight. My outdoor setup has a tillering tree bolted to it. I keep the whole thing outside year round, except the scales, which I bring inside. I just have to give the vise a good soaking of WD-40 once in a while.
