Description

A wooden side bead plane composed of three parts.
a- The body is made of hardwood and is rectangular in shape. There is a protruding cheek on the bottom 2/3 of the front face. The top corner on the heel end is rounded. The sole is curved concavely in the shape of a parabola to match the cutting edge of the iron. A wooden spline runs lengthwise near the cheek edge to close the parabolic groove. Inscriptions on toe read: "J. Dawson/MONTREAL"; "I BLOWER". Inscriptions on heel read: "BLOWER"; "5/16"; (C + Carl/a + M/75)?".
b- The wedge is made of the same hardwood as the body. It tapers to a point on one end. The other end is asymmetrically chamfered. A small cut-out near the chamfered edge allows for easy handling.
c- The iron is made of a dark grey metal. It is a long, thin piece of metal that abruptly expands where it exits the throat of the plane. The cutting edge is shaped to make side beads. The cutting width is 5/16".

History

Side beads, or beading planes, are used to put a bead along the edge of a board, and can be used in many situations, such as back boards, the bottom of table aprons, or along shelf fronts. 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. For a different treatment, running the plane along two sides of a corner will produce a 3/4 bead on that corner.
