A wooden grooving plane consisting of three parts. The plane is particularly thin.
a- The body is made of hardwood and is rectangular in shape. A cheek protrudes slightly from the top half of the front of the piece. The side and top edges of the cheek are rounded. The bottom edge of the body is chamfered on the back side. The throat is exposed on the bottom half of the piece, situated around 13.5cm from the heel. Stamps on toe read: "R WATT"; "3". Stamps on heel read: "(SHEPLEY)?"; "J MARSHALL".
b- The wedge is made of a similar hardwood as the body. It tapers to a point on one end and is rounded on the other. A small cutout on the front-facing edge of the wedge allows for easy handling.
c- The iron is composed a long, thin piece of dark grey metal. The cutting edge is slightly wider than the rest of the piece. The cutting edge is slightly rounded in a convex way. The width of the cut is 3/16".
Grooving planes are used to cut straight grooves, or rabbets, into a working piece. They are traditionally used for drawer bottoms or rear walls. They can be used in conjunction with tonguing planes, which create two parallel slits in a piece of wood. The grooving plane can then dig out the excess material and create a clean groove. Other names include dado planes, ploughing planes and matching planes when combined with a tonguing plane.
