I want to build a guitar rack that will hang on the wall. My plan is to use a plank for the back (I have either maple or bloodwood for this—am leaning toward using the bloodwood). The guitar will sit very upright, and be supported underneath by two arms that are dovetailed into the back plank. I have walnut, purple heart and teak to choose from (leaning toward the teak). I will use the same wood type to make a support to go around the neck of the guitar to hold it into place, using a dowel and a “restraining bar” of wood to hold the guitar in, as well as open it to remove it. Still practicing my dovetails before I get into the real deal. Any thoughts or suggestions would be appreciated.
