Some tips for building your Resonator ukulele.

The sound well hole needs to be 6" in diameter. Any larger and the coverplate screws will not have any material to screw into. The cone is 5-7/8" dia. For the sound well, I use ¾” (19mm) Baltic plywood and rebate the inside edge 3/8” wide by approx. ½” +/- deep. The final depth that I look for is approx. 5/8” including the thickness of the top so that the top of the biscuit, when installed, is flush with the coverplate or a little bit proud. The action is then determined by the height of the saddle. I also install a 7” x 5/8” x ½” beam under the sound well with a sound post in the centre connecting to the back. This gives added support to the shelf at the bottom of the sound well and also transfers some of the sound energy to the back of the instrument. The same idea as a violin.
