When building balsa models, its a difficult chore to shape the wing's leading edge. Usually you begin with rectangular balsa stock and do some carving to get the approximate shape, then finish with sanding blocks. We are able to produce custom-made sanding tools with the correct NACA airfoil shape, which can help finish the job with the exact shape you need. For example the F4U Corsair's airfoil is NACA 2415.

In order to make new versions of these tools we need a full-size drawing of the model's wing rib, including the leading and trailing edges. If possible, the NACA airfoil number. We have produced two types so far!
The tools are about 5 inches long and come with 120-grit sandpaper attached. Note: the color of the sandpaper may vary depending on the stock that's used. You can remove the paper if needed by applying foam-safe CA activator to dissolve the glue. New sandpaper can be attached using a spray contact cement such as 3M brand "77".
We also produce several NACA sanding tools specifically for Derek Micko's "Fun Scale Models" line of small balsa aircraft, which all use a flat-bottom "Clark Y" airfoil. Derek Micko produced this video demonstrating how the tools are used.
The tool is designed to be used with it placed on a flat surface. The bottom side of the tool has no sandpaper so it can slide easily and the tool aligns to make the correct airfoil shape on the top and bottom of the leading edge. The top sides of the tool has an additional flat sanding surface which helps with the grip!
This picture illustrates how you may use a marker to mark the front of the balsa LE stock to be an indicator showing when the tool has finished the work. This will help so you don't sand off the front of the LE.
