Robert Bourdeau made himself a pair of planes, a left-hand plane and a right-hand plane, that allow him to plane in the direction of the grain no matter which side of the panel he might be working on. They work better than a shaper and were cheaper than custom-ground shaper knives. Here he cites the research he did to find out how to make the planes and the project planning that determined the plane’s profile, field, shoulder, and bevel. He explains how he decided to set the iron’s skew and how he ground the cutter and the scribing spur. Multiple photos and drawings illustrate the plane construction.
