I had to go out to the shop to measure the blade, it's 3/4"x .060" x 106". While there I took another pic.
The base is channel iron and the screw for the vise is from an old tripod car jack.
Of course the screw is right hand so I decided to use gears between the handle and the screw. I then decided to use different size gears and the handle slides in to select mechanical advantage for tightening and out to speed it up for rapid travel.
I had two gears the same size and made two smaller ones out of brass on my shaper (actually I made one wide one and parted it into two gears on the lathe).
