A wooden tonguing match plane consisting of 3 parts.
a- The body is rectangular and made of a dark brown hardwood. A cheek protrudes from the bottom half of the front body. An adjustable wooden fence sits along the back edge of the sole. It is loosely secured by two large slotted screws. Stamps on the toe read: "G. DAVIS"; "(S)METHURST"; "J.W.(L)ANE"; "I BLOWER". Stamps on the heel read: "I BLOWER"; "T. SMETHURST"; "3/4".
b- The wedge is made of the same hardwood as the body. It tapers to a point on one end and is slightly rounded on the other. A curved cut-out below the head allows for easy handling.
c- The iron is a narrow strip of ferrous metal. It abruptly widens near the cutting edge. The cutting edge consists of two parallel chisel blade separated by a short gap. The width of each cut is (l-r): 1/2"; 5/16"; gap 5/16".
Tonguing planes cut two parallel grooves in a workpiece. They are used in conjunction with a corresponding grooving plane to create tongue-and-groove joins. When used together, they are known as match planes. The iron of a tonguing plane contains two sharp edges and a central notch that leaves a raised ridge.
