Description

Wooden double bead plane consisting of three parts.
a- The body is rectangular and made of brown hardwood. A bell-shaped hole situated 9.5cm from the toe acts as the throat of the plane. The hole extends down to the sole. The sole has two protruding wooden slats that frame the cutting edge of the iron. The top edges of the body are rounded to ease handling. Stamps on toe read: "J. DRYBURGH/BRIGHT, ONT"; "I BLOWER". Illegible white inscription on toe. Stamps on heel read: "I BLOWER (x2); "3/16".
b- The wedge is made of the same hardwood as the body. It tapers to a point on one end. The other end is formed into a "handle" with chamfered corners. A small cutout allows for easy handling.
c- The iron is made of a dark grey metal. Its width is very thin to fit into the throat. It abruptly expands at the opening of the mouth. The cutting edge forms a concave half-circle. The width of the cut is 3/16".

History

Double-bead planes allow the artist to cut a full 180-degree bead with a single tool. A very versatile plane, these were, along with hollow and rounds, perhaps the most common molding plane produced. These are one of the easiest molding planes to use, with an integral fence and depth stop, and no spring. (The plane is held vertically.) Simply hold the plane against the edge of the stock being profiled, and make passes until the depth stop prevents any further cutting.
