Leg vises
During the 18th century the leg vise was king. If a workbench didn't sport a European-style shoulder vise, chances are it had a leg vise. This was before the mass-produced iron face vise became common. Once this "Record-style" iron vise took over, the leg vise almost disappeared, and it's a shame that it did. Leg vises offer greater work holding capabilities than iron vises. Without the two guide rods of the iron vise, workpieces can be held right up against the screw, virtually eliminating racking and providing a better overall grip. Iron face vises provide around 4" of workable depth from the top of the bench to the screw and guide rods. Leg vises are usually more than double this, around 9". Leg vises are also more powerful due to the large lever provided by the lower position of the fulcrum. Leg vises are also simpler and easier to maintain than iron vises. The auxiliary wood jaws necessary for iron vises are unnecessary with a leg vise since the vise itself, along with the bench's leg and top, forms the jaws of the vise. This also means you can build the vise in your own style, using wood of your own choosing. The leg vise is not only functionally excellent, but also aesthetically pleasing and unique.

Traditional leg vises work around a simple principle. A single screw passes through a moving jaw or "chop" and provides the clamping force. The screw engages a threaded hole (usually in the form of an attached nut) in the bench's leg. A means of preventing rack is present at the opposite end from where the wood is held. Traditionally this is a perforated length of wood attached to the chop (the "parallel guide") through which a pin is inserted to match the workpiece thickness. But other means have also been used, such as a second threaded rod, or a scissors-type mechanism known as the St. Peter's Cross. Our version of the latter is the Crisscross.

The Glide
The Glide makes holding your work quick, easy, and pleasurable. The Glide uses a clever combination of components to deliver incredible clamping force with minimal effort.

• The Handwheel

We've done away with the traditional "tommy bar" handle in place of a massive cast iron hand wheel. T- bar style handles offer one distinct advantage: lots of leverage. Otherwise they can be clumsy, slow, and can interfere with your work and your body. We've engineered the Glide to deliver rock-solid workholding without the need for the big lever of a tommy bar. The massive handwheel allows you to operate the vise with minimal effort. Acting like a flywheel, the handwheel turns the screw and allows you to rapidly adjust the vise with a quick spin. You can open the vise to full capacity (typically 9") in about 4 seconds. Closing it is just as quick and easy. With three knobs oriented at 120 degrees around the wheel's perimeter, there will always be a knob between the 10:00 and 2:00 position. This makes for very convenient operation. Moving a knob from 2:00 to 10:00 (1/3 revolution) moves the chop over 1/8"; more than enough to remove your workpiece. Operating the vise is fun. Giving the handwheel a healthy spin opens the jaw wider and more quickly (use one of the knobs, or grasp the rim itself) and closing the vise from this position with another healthy spin closes the vise rapidly against your workpiece. In most cases, further tightening of the vise is unnecessary. The Glide M features a refined, fully-machined iron handwheel with durable, acrylic-infused Dymondwood knobs. Sporting a more traditional look, the Glide C features a sand-cast iron handwheel with acrylic-infused beech knobs.

• The Screw

A rolled-thread double-lead acme screw is the heart of the Glide. At 4 turns-per-inch, the double lead moves the chop 1/2" per revolution, twice as fast as typical metal vise screws. Roll threading creates a hardened, polished thread for smooth action, and consolidates the molecular structure for durability, unlike screws with cut threads. We turn our nuts from solid billets of steel and tap them to work sweetly with the Glide's screw.

• The Crisscross

The Crisscross mechanism is an integral part of the Glide. The mass and free spinning action of the handwheel are provided with unencumbered movement over the vise's entire range by the Crisscross, which completely supports the weight of the chop and Glide components. Additionally, the Crisscross totally eliminates the traditional wooden parallel guide and its adjustment pin. No need to stoop over to adjust for thicker boards, the Crisscross does it automatically. It's also much faster to build and install than a traditional parallel-guide equipped leg vise.
