Calibration set

Calibration set: cut it once for every new material, before anything that has to fit. The kerf gauge measures the beam, the slot gauge how wide a slot your sheet needs, and the joint pairs which kerf setting makes finger joints that hold.

Download size: 420.9 × 49 mm. 8 parts on 1 sheet.
