When I built my bench 38 years ago as a neophyte woodworker I wanted a rigid tail vise which did not rack.  Over the years people have asked me about it’s design, so I figured I would post it here.

I saw something similar and modified it for my use.  I purchased a quality vise screw and had the rest of the pieces fabricated from my design by a local machine shop.   I drew it up pre-computer days and have since lost the paper, so I redid the drawing. 

The sliding bracket on stationary rods is not original to me, but I have not been able to find the reference I used, or even other examples.  I admit is it a “little” over engineered, but I was just starting out and it has worked well all these years.  It continues to rack very little over the 24 inches (0.06 inches) and operates smoothly after 38 years.
