Sine Vise Height Table

Sine Vise   Space Blocks

The sine vise is a screwless vise that sits on two cylinders. One cylinder is the axis of rotation of the vise body. The second cylinder is positioned very precisely at a known distance from the axis of rotation. Knowing the sine of the angle you want and the length of the hypotenuse (the distance between the centers of the cylinders), you can easily calculate the distance that the movable cylinder should be above the base of the vise. See the height table below for the correct height of space blocks for angles from 1 to 60°.

You use space blocks to raise the movable cylinder. Space blocks come in a set of various thicknesses so that you can assemble them to make any distance that the movable cylinder needs to be raised. Each space block has a threaded hole in the center so they can be assembled to form a riser of a specific thickness.
