This conversion kit allows your Veritas Small Plough Plane to accommodate tongue-cutting blades as well and straight blades over 9.5mm wide. It clamps and supports both sides of the cutter to prevent twisting in use. The kit is composed of a 125mm long machined ductile iron skate with a brass locking knob and a parallel adjustment screw (used to ensure skate and fence alignment). Easy to install or remove from the guide rods. Made in Canada.
