molding plane 02

Molding planes are unique in the shapes they can furrow in wood. While other plane soles are at, they are curved, and the blades follow this pattern at a 45° angle. Molding planes share with shoulder planes the ability to cut to the edge since the blade and the sole are the same width. The traditional molding plane is a thing of complicated angles, slots and curves, that rather intimidates the would be plane maker.

An elegant solution is one that simplifies, and this design qualifies for that definition of elegant. e blade is a single piece of O1 tool steel with-out elaborate shaping save for the cutting bevel. The body is a core the width of the blade with two 14” sides. The wedge is fitted while the body is half made and its inner recesses observed.

In the rabbetting plane we have a plane that satisfies all the requirements of such a molding plane save for the sole shape. Building on this design platform we can accomplish the shapely furrow by contouring the sole and matching the required blade profile. The example is a No. 12 hollow which cuts a curved trough, or hollow, ¾″ wide. The No. 12, like other numbers in the series, refers to the width of the plane in sixteenths. The planes were made in matched pairs of hollows and rounds. Making such a matched pair starts with the hollow which can then be used to form the round’s sole.
