In metalworking projects, one often needs to shorten threaded rods, bolts, and cap screws. This method is simple and reliable, and the jig is simple and easy to make. The plate with the various threaded holes is welded to a piece of channel. The channel must be long enough to be able to be held securely in the vise of a drop saw, wide enough to allow access to insert and remove the cap screws, and high enough to cope with the depth of cut of the drop saw. I used 100 x 50mm channel, 140mm long and 5mm thick. The holes were drilled and threaded before the welding was done.

The jig is positioned in the vise so that the drop saw blade just skims the face of the threaded plate.
