Grooving With a Screen Tool

Many people use a Dremel tool to cut a groove for the carbon stiffening rod in a foamie wing, but it’s easier to use a window-screen-repair tool. It has a disc on both ends—one with a semicircular groove around it and the other with a rounded (convex) outer edge. To use this tool, cut a skin-deep slit using a straightedge and a modeling knife, and then groove it with the rounded disc. Lay the carbon rod in the groove and press it in flush with the grooved disc. Remove the rod from the wing, add CA, and press the rod back into the groove.
