Abstract
A method and apparatus for a blade clamping mechanism in a woodworking plane that allows a plane iron as wide as the plane body itself to be clamped in a wedge shaped slot in the plane body. The slot begins at a point tangent to a waste ejection hole proximate a front area of the plane running diagonally towards the spine of the plane body before looping back short of the spine to return diagonally through the sole forming the mouth together with the waste hole. The loop forms the widest point of the slot, while the tangent forms the narrowest point of the slot. The rear surface of the slot serves as the ramp for the plane iron. The plane iron is clamped by a floating pin mounted in a hole drilled longitudinally through the spine, perpendicular to the ramp, and terminating at an inspection hole. The floating pin is retained between the under side of the plane iron and a conical shaped point of a screw threaded from a back of the plane body diagonally to the floating pin. The pin and screw are viewable through the inspection hole.
