Latta Thicknessing Gauge

The Thicknessing Gauge is for trimming veneer strips (stringing) to precise thickness. The hole cut in the body provides a clamping surface. The tool should be either locked into a vise or clamped to a bench. Merely trying to hold it by hand will not work. Clamp the tool so that the cutters are positioned away from you.

Hard Maple body. Blades are made from Swedish Spring Steel. Other parts are Brass and Steel

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.

Blade Specs:

.050” (1.27mm) Spring Steel RC 52.

Use: The tool is essentially a scraper. Set one opening for roughing materials to approximate size. Set the other opening for final thickness. To thickness your material, pinch the stringing between your fingers and pull it upward through the opening. Position two fingers in front of the mouth as guides. Pulling the stringing upward prevents it from instinctively going to the bottom of the opening.

As the stringing becomes easier to pull, work it towards the bottom of the opening. It should give a clean shaving. If the stringing is chattering, try pulling by the other end. If the cut is producing dust rather than a shaving, the burr needs to be re-established.

If your veneer is brittle or has highly figured grain, you may get better results pulling the edge of the veneer sheet through the thicknessing gauge before cutting strips of stringing.

For more information on using the Thicknessing Gauge and how to use stringing inlay in your work, we recommend Steve Latta’s DVD Fundamentals of Inlay: Stringing, Line & Berry.

Sharpening the Cutter:

The thicknessing gauge acts as a scraper, and so both blades cut with a burr. To sharpen, first hone the bevel of the blade lightly on 150 grit sandpaper or a medium stone. Remove burr raised by honing, then re-establish the burr with a carbide burnisher.


Keep tool clean and occasionally coat with oil. A 50/50 mix of boiled linseed oil and turpentine is what we use.


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.
