Description

A wooden bead plane consisting of 3 parts.
a- The body is rectangular and made of a brown hardwood. A cheek protrudes from the bottom 2/3 of the front body. The throat cuts diagonally through the cetre of the body and is exposed through the cheek. The sole is curved concavely along the length to match the cutting iron. The sole is flat on either side of the curve. Stamps on the toe read: "DRYBURGH/N.E. HOPE/ONT"; "I BLOWER". Stamps on the heel read: "I BLOWER"; "5/16".
b- The wedge is made of a similar hardwood to the body. It tapers to a point on one end and is rounded in an elliptical form on the other. A cut-out below the ehad allows for easy handling.
c- The iron is a narrow strip of dark grey metal. It abruptly widens near the cutting edge. The cutting edge is curved concavely, with the proper left side of the curve extending further down than the right. The width of the cut is 5/16".

History

Bead planes are used to put a bead, or a convex groove, into a workpiece. They are considered molding planes. Beads can be put into any straight piece, but are popular in tables, shelves and doors.
