Square Gauge

Attach these to a framing square to improve the ability to align the square to an edge or to set an angle to make repetitive angle marking easier. Or use wherever you have a flat straightedge that you want to butt against an edge of the workpiece. Obviously not as precise as the machined brass product these were modeled after, but good enough for what I needed.

Hole is sized to be tapped to 1/4-20.
