Introduction

The Veritas

®

 Quick-Release Tail Vise is a reworked 

version of the well-known tail vise that is generally 
built into the front apron of many cabinetmaking 
workbenches. While workpieces can be clamped in the 
sliding jaw, the quick-release tail vise is primarily used 
in conjunction with bench dogs, either on top of the 
workbench or along the side of it.

The main problem with most sliding tail vises is 
that they require a signifi cant amount of work to 
install them. Generally, retrofi tting a tail vise onto an 
existing workbench requires extreme modifi cations 
to the workbench, and a new workbench that is to 
incorporate a sliding tail vise must be designed 
around the vise’s mechanism.

The Veritas Quick-Release Tail Vise has been 
specifi cally designed to simplify the installation process. 
The vise mechanism is mounted onto the underside of 
a workbench top and a user-made jaw (e.g., a slab of 
material with dog holes) is attached to the mechanism.

This vise features a quick-release mechanism for fast 
adjustment of the opening. The positive action of the 
mechanism means the vise can be used for spreading 
workpieces apart, as well as for clamping them. 

As delivered, the vise is confi gured for mounting on 
the right end of a workbench; however, it can easily 
be reconfi gured for mounting on the left end of
a workbench.
