Massive jaw provides secure, mar-free . clamping of workpiece BOLT-ON FACE VISE Rear Jaw extension matches front jaw and hides metal jaw of vise benchtop I idea to screw a couple wood jaws in place for protection. There is one problem with bolting a vise like this in place. If you want to clamp a long work-piece along the front edge, it won't rest flush with the front of the bench. This can make it a hassle to add additional clamps for support. Building It In. If you're building a new bench, you can solve this problem by "burying" the rear jaw into the apron of the bench (Cross Section at right). By creating a pocket in the apron before it's attached to the top, you end up with a built-in wood "jaw." Quick-Release. One "upgrade" to look for in a bolt-on vise is quick-release feature. With a quick-release, you don't have to spend a lot of time rotating the handle of the vise around and around to open or close the jaws to match your work-piece. You can do it in one quick and easy motion. The Jorgensen vise shown here features a half-nut that releases when you rotate the handle counterclockwise. Other manufacturers use a spring-loaded lever on the front to accomplish the same thing. The Next Level. A face vise is just one way to make a workbench work harder. For a couple more ways, take a look at the vises on the next page. Prevent Racking About the only problem you'll run across with a face vise is when you clamp a workpiece near one edge, as in the photo at right. As you start applying pressure, the vise begins to rack, or twist, to the other side. Besides being hard on the vise, the jaw won't clamp squarely against the work, so it isn't as secure. To solve these problems, you can use a handy, "anti-racking" block on the opposite side. The block is just a thick piece of hardwood with a number of "s teps" cut into it. To handle workpieces in a wide range of thickness, the steps are graduated in Vs" increments.
