Here are a couple more pics. This first one is the back graft being cleaned up. This strip of cross grained wood is ther to support the glue joint between the two back halves. After it is glued in it is sanded down to a bring the sides down to a thin edge. If they where left full height they would become stress risers going right along the grain of the back halves increasing the possibility of causing cracks:

Here I am cutting out the sound hole:

I use binding tape on the bottom of the cutter to keep it from marking the top:

A nice sharp blade on the cutter gives a clean cut:

One of the practices I picked up while taking classes with Ervin Somogyi years ago was to save the hole cutouts with the pertinent details of the build for future reference. Of course Ervin has a lot more holes than I do
