RE: Workbench Height
Mine is 40" tall, 2' deep and 8' long. Perfect to stand up and work at or sit on bar stool and work. I took me a couple of hours to figure out how tall I wanted it but I finally sat on the bar stool and decided that I wanted the bottom of the bench to be atleast 1 1/2" above my legs. I framed it out with 2x4's and used piece of 3/4" sanded ply for the top and I sanded it even more for a nice, smooth, dead flat surface.
