Using a Dial Indicator and Calipers to Achieve Tight Fitting Finger Joints
Greene & Greene (G&G) finger joints are distinctive in their size and spacing. The joints are unlike any other finger joint I’ve seen, which is probably why I’ve been so adamant about learning how to produce them. One of the methods I found for cutting G&G finger joints involved making templates for various finger sizes and a handheld router. You could easily amass a large collection of templates since the G&G motif is synonymous for having several finger spacing configurations within a single furniture piece. Darrell Peart’s method of machining finger joints on the table saw, with calipers and a dial indicator on a dado sled, made the most sense to me. This method required no templates and the fit could be dialed in with laser-like precision without much fuss.
The dado sled is not much different than your normal cross-cut sled.
