...Just a few words might be useful here.
..The goal Tap Tone RIB frequency is 213 HZ horizontally, all over the exterior rib surfaces.
..This tap is applied to the ribs horizontally from the side (either inside or outside and 90 degrees to the surface. Compare to the wood reference tap tone scale tool. Adjust the areas that are above 213 by sanding or scraping the surface in the region that is too high until it becomes the 213 Hz goal frequency. Leave the too low areas alone. Material can be removed from either inside or outside of the ribs to the same effect. A (1) mm thick rib (0.0394") should be close to the goal frequency automatically.
..To deal with areas that are too low in horizontal Tap Tone; remove a small amount of material from the inside of the glue liner strips on their inside direction edge evenly on both sides to raise the Tap Tone up to the desired 213 HZ.
(Be sure to leave the glue surface its full width for glue joint strength.)
