See Cold Saw Index for Specific Design Breakdown:
Rotate the blade.
Move the blade into the material.
Angle the blade relative to the material.
Hold the material.
General Design Requirements
Precision requires rigidity.
Functional design avoids interference between mechanisms.

Precision center angle locking mechanism with deviation of less than 1 degree
Precision perpendicular descent with vertical cutting plane angled within 1 degree.
Up to 45 degree cuts for at least 1" wide materials.
Clamping materials of at least 4" width.
