Cold Saw/Understand4
Vise
The vise holds the material to be cut.
The vise should be auto-centering such that the vise can accommodate angled cuts more effectively and facilitate the blade descent at the middle of the material width.
For a given cut width, the maximum cut height is determined by the diameter of the blade and the blade supports.
The vise is screw-fastened to a surface below such that the vise can be easily removed to facilitate cuts with irregularly shaped materials.

Dimensions
The mounting holes for the vise are 12mm diameter to fit the M12x1.75 screws used uniformly.
The vise shafts are 31.8mm diameter, the same diameter as in the rotation assembly.
The vise threaded rod is M30x3.5 to fit within 32mm diameter holes uniformly used for the vise shafts.
Depth of the blade slot is 25.4mm (20mm required for 350mm diameter blade, 115mm material width, and up to 45 degree cuts)
