Description

Wooden dropped cove molding plane comprised of three parts, a wooden rectangular body (a), a wooden wedge piece (b), and an iron (c). The iron and the wedge fit together inside of and angled hole through the plane's body and allows the iron to stay in place as it is exposed out of the bottom of the plane. There is a portion of a sticker on the proper left front side of the plane with "MEDER FABRIKAAT" typed on it. The area above the sticker portion is lighter than the rest of the plane's wood, meaning that some of the sticker has fallen off or is lost. Stamped on the front proper right side of the plane is "[M G W H]". Stamped on the heel of the plane is "I BLOWER", "34", and "[5/ ]". Stamped on the toe edge is "M G W H", "I BLOWER", and "J.N." below a symbol of a crown.

History

Though they consist of only three parts—a body, a blade, and a wedge—molding planes are actually complex precision tools. The sole is shaped to the reverse of the molding and the bedding angle of the blade (its pitch) is directly related to the material it is intended to cut: 45º for softwoods, 50º for general use and 55° to 60º for hardwoods. Some planes have strips of a dense wood (usually boxwood, though lignum vitae was occasionally used in early planes) inserted where the sole receives the greatest wear. Known as boxing, these strips extend the life of the tool. During the first few passes, the plane may be tilted or ‘sprung’, with its fence running along the edge of the work. Springing gives greater control, but it also allows the mouth to be of a consistent width to support the shaving and take a smooth cut. Multiple passes take wider and wider shavings until the integral depth stop makes contact and the molding is complete.
