Turn a machinist's vise into a tail vise

Here's a trick I came up with when I wanted to do some hand-jointing on a long workpiece: Secure one end of a long pipe clamp in your machinist's vise, prop up the screw end of the clamp with support blocks, and clamp your work piece. This arrangement provides rigid support in only a few seconds, and gives you full access to the workpiece's top edge.
