You can convert the Veritas Low-Angle Block Plane and Standard Block Plane into chamfer planes in seconds with this cunning guide. Easy to install - you first set the chamfer width on the guide, then install the guide by unscrewing the front knob of the plane, replacing the toe piece with the chamfer guide and tightening the knob again. It is ready to go. Adjustable for chamfers up to 13mm wide, the guide wings are fixed at a 90° angle to hold the plane body at a consistent 45° to the work face. Made of anodised aluminium.
