Bench Plane Tuning Kit

The Zeptix Supplies Bench Plane Tuning Kit contains everything you need to bring a new or vintage bench plane to peak performance. The kit includes a precision-ground granite reference plate for sole lapping, three grits of adhesive-backed silicon carbide paper cut to plate size, a machinist’s straightedge for checking sole flatness, a brass adjustment wheel replacement for smoother depth setting, a frog-seating file for cleaning contact surfaces, and a detailed tuning guide that walks through the full process from disassembly to final test shavings. The granite plate is certified flat to within one ten-thousandth of an inch, providing a reference surface accurate enough for serious tool tuning. Most new bench planes arrive with soles that are close to flat but not truly flat, and vintage planes are almost never flat after decades of use. Lapping the sole on this kit transforms a frustrating tool into a precise instrument that produces gossamer shavings with minimal effort. Suitable for all standard bench planes from number three through number eight, and the guide covers both bevel-down and bevel-up configurations.
