This ingenious device from Veritas can be used for the quick and accurate setting of saw blades, mitre fences and planer fences to any one of five pre-determined angles. These angles are 45°, 54°, 60°, 67.5° and 75° and are those used to produce frames and other structures with either 4, 5, 6, 8 or 12 sides. The gauge can be used horizontally, typically to set a mitre fence, or vertically as shown for setting planers, table saws, bandsaws and the like; in the vertical position the central knob is removed and used as a stabilising base, leaving both hands free for adjusting the machine. Construction and accuracy are to the Veritas usual high standards and there are copious instructions for use included. The overall size of the gauge is 215 x 150mm.
