This simple attachment for the Veritas router plane lets you score a shallow groove to accept inlaid purfling, banding or stringing, taking advantage of the plane’s fence and depth-adjustment mechanism to precisely control groove position and depth.
The cutter head holds a pair of included single-bevel slicing blades that score crisply defined groove outlines across, with or diagonal to the grain. By using a chisel or switching to a standard router plane blade matching or smaller than the width of the desired groove, you can quickly hog out the waste between the scored lines.
An included set of shims and spacers lets you set blade spacing to define groove widths from 1/16" to 15/32" (1.5mm to 12mm). Set includes five each of four sizes of plastic shims (0.002", 0.005", 0.01", 0.02") and one each of 0.04", 0.08" and 0.12" steel spacers.
To score a groove parallel to a straight edge, a fence (available as an optional accessory for the Veritas router plane) is used to guide the cutter blades at a consistent offset from the work edge. For following curved edges, a non-marring brass stylus (included with the inlay cutter head) can be threaded onto the fence rod in place of the straight fence.
Replacement blades available (sold individually). Made in Canada.
