In the Ryder No. 90 Bull Nose, the upper section is movable, forwards or backward 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 after disassembling the plane. The plane is carefully ground, finished and polished. The plane’s body is fine grey cast iron. A finger recess on both sides and a well-rounded upper section combine to ensure a comfortable grip. Precision ground, the sole is flat and the sides are square to the sole. The 25.4mm full width blade is micro adjustable for precise control of the depth of cut. The blade is half a smidgen wider than the body making it easier to work in corners.
