This is an idea originally put up by Chris Schwarz (editor for popular woodworking magazine) on his blog. It’s a take on the twin screw vise based on several books from the 1800’s. The idea of being able to put a twin screw vise onto my bench when I need it and get it out of my way when I don’t was something I couldn’t pass up. I always wanted one but didn’t want to dedicate that much workbench space to the construct and now I have the best of both worlds, there when I want it, on the shelf under the bench when I don’t.
The version Chris built used a couple of “F” clamps or some long hold fasts to secure the vise to the bench,, just like I used it the first picture. but I didn’t like the “F” clamps crowding me on either side and I wanted to use my shorter holdfasts to do the work. So I dovetailed in a piece of oak to act as a back ledge and hold the vise in place.
It works like a dream, the biggest cost for building this is not the lumber but the threading box for cutting the threads into the screws and the back board of the vise, I used a 1 1/2” box to cut for this vise that I bought off of eBay, but I know woodcraft carries them. (I’m sure that’s where mine originally came from)
The vise adds 5 1/2” of height to the bench which brings joinery work up to a level that relieves the dovetail hunch that is developed after a day of half bending over at the traditional vise. It has the capacity to hold a board 26” wide and probably 8” thick if I wanted. (God what a chunk of wood that would be.)
Anyhow enjoy, as always I detailed the build further on my blog you can read more about it here:
