The hardware inside consists of a steel mounting plate attached to the front edge of the workbench. This fixed plate has a threaded "nut" that accepts the screw of the tail vise. As you turn the handle, the vise assembly slides back and forth along the mounting plate.
To keep the vise level and sliding smoothly, a pair of steel guide plates are sandwiched around the top and bottom edges of the mounting plate.

without any interference. To do tills, the vise has a few dog holes that align with a long row of dog holes in the front edge of die bench. Widi a pair of bench dogs, holding just about any workpiece is a snap.
Note: For more versatility, you can even clamp a workpiece between the face of the slidi ng jaw and the bench.
How a Tail Vise Works. Although a tail vise looks like a solid assembly, ifs really a wood box with an open back. It's the hardware inside that's the secret to how a tad vise works. To see what I mean, take a look at the illustration above.
