Our collaboration with Educator/ Cabinetmaker, Steve Latta, began in 2006, when he approached us about designing a selection of inlay tools based on the tools he’d developed over many years of studying and creating 18th century furniture. Our inlay tools are the first commercially available tools designed specifically for stringing inlay. These tools cut precisely and are easily adjusted. Additional blade thickness offer maximum design flexibility.
When arcs cross or intersect each other, cut and fill the first arc. After the glue has set for a few minutes (yellow glue is recommended) and the stringing has been leveled to the surface, cut the second arc slicing right through the stringing of the first. This method saves time and leads to cleaner work.
The cutting tips must be sharp. To check, angle the tool so that only one Radius Cutter tooth makes contact with the wood surface. Make a cut cross-grain. Roll the tool back and repeat the process with the other tooth. The cutting action should slice rather than tear the fibers. Keep in mind, soft or spongy woods are more likely to tear. If tearing occurs, the tips need to be filed until they function like a knife. Examine the tips of the teeth. If there are any flat spots, indicated by a reflection at the very tip of a tooth, the point needs to be re-established using a small triangular file.
For more information on using the Radius Cutter and how to use stringing inlay in your work, we recommend Steve Latta’s DVD Fundamentals of Inlay: Stringing, Line & Berry.
Grind outside bevels on an edge sander, sanding belt or grinding wheel, using a medium grit belt (120-150). To file the inside edges, use a 4" double extra slim tapered file. Hold the file perpendicular to the blade, and angled at 45º (this will line it up with both bevels).
File lightly, touching both teeth at the same time, until you no longer see light reflecting off the points.
Make sure that the tips of the two teeth remain even. After filing, smooth the faces of the cutter on a honing stone.
Materials and workmanship are guaranteed for the life of your tool. Call for repairs or replacement parts. We are available for advice if you ever have a problem using your tool.
