When two inlaid banding lines meet at a corner it's essential that the outside corners of the router-cut grooves be perfectly square, as even a slight inaccuracy can be conspicuous. Developed in consultation with accomplished British boxmaker Andrew Crawford, this machined precision jig offers a solution. It has thin 1-3/4" long ribs on the underside of the anodized aluminum base to permit stable, accurate registration in a pair of perpendicular grooves as small as 1/16" wide and 1/64" deep. Four embedded 1/4" rare-earth magnets ensure the included corner chisel travels true in the jig. Made of long-wearing A2 tool steel, hardened to Rc60, the 3/8" square chisel is precisely ground with a 35° bevel on each face. Also useful for tidying the corners of recesses for inlay panels, stringing, or on any 90° corner of a router-cut inlay groove. Made in Canada.
