Description

A wooden sash coping plane composed of 3 parts.
a- The body is rectangular and made of a brown hardwood. A cheek protrudes from the bottom half of the front side of the body. The underside of the cheek is curved to accommodate the cutting iron. The throat is centred and slopes down toward the toe. The sole is flat. Stamps on the toe read: "DRYBURGH/N.E. HOPE/ONT."; "I BLOWER". Stamp on heel reads "I BLOWER".
b- The wedge is made of the same hardwood as 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 head allows for easy handling.
c- The iron is a long, narrow strip of ferrous metal. It abruptly widens near the cutting edge. The cutting edge is curved in a half-bell shape. The width of the cut is 1 1/8".
