Precision vises are a great accessory to have and makes setting up work pieces fast and easy. Here's a few that I was able to make over the past 60 years. I was a mere fourteen years old on this one. It's made of O-1 oil hardening tool steel hardened to 60 RC. This design is far more difficult to make; but has its' advantage in use. Note the two piece screw design,, the smaller on is a LH thread. While the bigger one is RH. Turning the handle moves the jaw twice the distance, yet a stronger holding power than a coarser thread... And has a nice flip up "speed Lever" added to the knob...

All the other are made from low carbon steel and case hardened. Called Nitriding Where Nitrogen is diffussed into the surface making it 70 RC. . Leaving the core soft and more stable. Baby one, And a sine vise.. All are still within tenths of being square.

Here's a setup using my vise on a magnetic sine plate to grind the ends of a blade for a Precision Protractor.

Here's where the two grinding vises of the exact same size came in handy. Two vises vises and a parallel on either end to grind the edge of an 18" long blade.
