The Ryder No. 19 shoulder plane cast from fine grey iron, is precision machined, precision ground and polished to ensure accurate results. A finger recess on both sides and a well-rounded upper section combine to ensure a comfortable grip. The sole is flat and the sides are square to the sole. The 19mm full width blade is micro adjustable for precise control of the depth of cut. The blade is a fraction of a smidgen wider than the body making it easier to work into the corner of a shoulder. The upper section is movable, forwards or backwards varying the width of the mouth for fine or coarse work. Removing the upper section completely, converts the plane into a chisel plane, useful when working on a frame, where the stile and rail rebates meet. A small setscrew inside the front section ensures you retain the original mouth setting when reassembling the plane.
