@dwalbert A shop that periodically floods is just miserable, I had that situation in my old shop. The leg vise is what I'm after too, I have a homemade Moxon vise, but I'd love to have something I didn't have to set up each time I need it. Still, the Nicholson bench is supremely flexible to hack, as you say. I've installed an end vise, a pop up bench stop, and a solution to hold my chisels and some other tools on the back edge.
