A while ago I made a vise of very similar same design. I don't know if I had seen this video and copied the idea, or just great minds think alike. My vise uses almost exactly the same design and clamps.
My vise is made of oak and I like the holes that are bored in the vise from the video, it will make adjustment easier, I'll going to drill some holes in my vise. You can see on the left end of my vise string. I strung both halves of my vise together so that the pieces stay together when not in use. My shop can be a bit of a mess, much of the time.
