Over the last week I've completed work on the soundbox of Joel's Engelmann Spruce and Honduran Rosewood Allegro Classical. At this stage of construction I do a lot of very important work with regard to graduating the thickness of the soundboard. I rout a preliminary channel around the top so that I can see the thickness and then I sand the top so that it's top graduates from about .100" to perhaps .070" around the perimeter of the lower bout. While I'm paying attention to the dimensions of the wood with calipers and a Hacklinger gauge, I'm also using my ears as I tap on the wood to make judgements about how much and where to thin the top. Once the binding is installed I repeat this process, listening carefully all the while. More soon... :)
