A couple of days ago I posted the wagon vises that I have installed in the “outside the box” workbench I’m building myself. Today it is the leg vise. It is a very simple mechanism. In fact you could call it plane if you were so inclined. (sorry).
The jaws of the vise are fairly traditional except for the ability of the outer one to travel vertically. It is very different when it comes to power source however. As I said in the other post we boat builder types do very much like our wedges so this vise is powered by an 8 degree vertical wedge that offers about 1/2” of travel. In concert with two shims and a series of holes 1” apart that is enough to cover the vise’s travel of about ten inches face to face. The bottom spacer strut is conventional.
I think the photos will explain better than I can:
1) The vise as it fits on the bench in level clamping mode. There are no shims in place and the outer jaw is exactly level with the bench surface.
2) The same setup from the business side showing the stop pins and adjusting holes. These are very easy and quick to set up.
3) Shows the outer jaw in elevated mode. There is a 1/4” shim slid under the wheel at its base so that the jaw is now 1/4” above the top of the bench and can work against a dog. Also a really easy setup.
4) Same setup, other view showing a 3/4” shim in use. You knew I’d slip a little marquetry in somewhere didn’t you.
5) The lower strut, marked off in inches to facilitate setup.
6) One of the best things about this vise is that when not in use you can, by simply pulling the pin on the wedge rail, remove the whole thing…. leg bruiser and all and put it aside while you do other work on the bench.
That about sums it up. It is, like it’s designer, a simple soul but a good worker.
I haven’t played with it much yet but I can say that I can lift the end of the bench by a board clamped in this vise. The bench weighs 300 to 350 lbs ,is 90% plywood and you can just about build it with a skilsaw and a hammer. The dovetails you may see in some of the photos are strictly cosmetic.
The bench is a couple more days off. Stay tuned.
Hope this intrigues some of you and more important raises a few smiles.
