Match Planes (tongue and groove)

Match planes, or tongue and groove planes, are made in pairs with one plane cutting the groove and the other the tongue for making the tongue and groove joint.  Both planes are fenced and the work pieces, when referenced from the same stock face, will line up flush when when put together.  The tongue plane is a standard side escapement plane and employs an iron with a slot in it the width of the finished tongue. The groove plane however is actually a type of fixed plow plane with a metal keel.  Because of the narrow profile this is necessary for strength, as wood simply would not have enough strength or ability to hold up under normal use.  The iron is located on the leading edge of the rear skate by means of a V groove cut into the back of the iron, and fits into the corresponding inverted V on the skate.  It is adjusted the same as any side escapement plane except for the fact the iron is not pressed against the blind side of the mortise, but rather located by the groove.

The match planes shown here are designed to cut the joint in the center of stock that is sized for the plane.    Both sizes of planes have the ability to be used on stock up to 1/8″ thicker than advertised size, but of course the tongue will then be offset, which generally is not an issue as long as care is taken to reference off the same face of each work piece.The groove is about .005″ wider than the tongue, allowing the boards to go together easily but without slop.  An offset tongue is actually beneficial if profiling the front faces of the boards with a bead or chamfer, as there is more stock between the face and the groove.  We are offering both 3/8″ and 1/2″ sizes to begin with. The 3/8″ size will work on stock up to 1/2″ thick, and has a groove width of 1/8″ thick.  1/2″ size will work on stock up to 5/8″ thick, and will have a groove width of 5/32″.

The planes will cut a groove 3/8″ deep and a tongue that is 1/4″ tall.  This ensures stock will butt together on the show faces, and also gives room for glue squeeze out when gluing boards together.  These small sizes are ideal for case backs when expansion needs to be accommodated. Simply nail in place and the tongue and groove joints allow for expansion and contraction while holding the boards in alignment.

Both planes are quarter sawn beech with tapered O-1 tool steel blades bedded at 50 degrees for heavier cutting.  Price for the pair is $495. They can be found in the store here.

Rabbet Plane

Currently out of stock.  More expected late 2018. We are taking orders now.

Rabbet, or rebate planes, are used to cut rabbets along the edge or a board, often as a precursor to using hollow and rounds. While still considered a side escapement plane, they do differ from most other molding planes with the design of the escapement.  Because the iron extents across the entire sole of the plane, the escapement is conical and also through the entire plane, and will help direct the shavings out the side.  Ours are “off the bench” in design, meaning that the shavings will eject out the left side of the plane (On a right handed version.) and onto the floor rather than the bench top.  We typically bed the iron at 50 degrees since these planes are meant more for heavy stock removal and can be set quite aggressive.  When making moldings, 80% or more of the material may be removed with this plane before switching to hollow and rounds or other shaped profiles.  Rabbet planes are easy to sharpen and it makes sense to use it for the bulk of the stock removal.

With no fence or depth stock, they are very simple and nimble planes to use.  The users fingers can extend below the sole and act as a fence.  The plane can also be tilted to allow the corner to ride in a marking gauge line to start a cut for the first couple of passes, which establishes a fillet to continue to guide the plane.  As an option, we make these planes with a boxed corner along the right side which will extend the life of the sharp corner for engaging the marking gauge lines.  The boxing is persimmon, and is cut on a bias so the grain is running at the same angle as the bed of the plane, meaning that the grain along the edge is mostly end grain.

The irons are tapered O-1 tool steel, hardened to Rc 60-62, the same as our other planes. They are thicker than the usual 1/8″ by about 1/32″ to give more rigidity in heavy cuts.

We offer widths of 5/8″, 3/4″, 7/8″, and 1″.  All can be made with or without boxing.  Price for an unboxed rabbet plane is $220, with boxed planes being $250.
