Chamfers must be scrupulously laid out and cleanly worked if they are to be effective. They should be gauged in pencil, allowing for an equal amount of wood to be removed from both sides of the corner, worked with bullnose rabbet-plane, chamfer or flat-faced Spoke-shave, scraper, flat file, etc. and checked in the length with a metal straight-edge. The ends are usually stopped and various forms are illustrated in 308:1-5, while 308:6 shows a simply constructed hardwood template which will give a constant angle to the slope of the stops. An old-type wooden chamfer-plane is shown in 308:7 which can be made up out of a

309 Working moulded section beech block about 5 in (127 mm) long and 1 in (25 mm) thick, or a standard wood rabbet plane can be converted. A square edged iron is used which is set to project to the depth of the chamfer, and the strokes must be gentle or the iron will tend to dig in. This type of plane can only work in the middle of the length of a stopped chamfer, but is useful for establishing the cut which can then be extended to the stops with a bullnose rabbet-plane.
