This project has been in sketch pads and in lunchtime conversations for several months now.
A couple of months ago I started takling the classes necessary to run a shopbot router at the local Tech Shop, and last week my first batch of marine plywood arrived.
So… I ran the CNC machine last week to make a cutout template and now I am starting to build the walnut in earnest.

When you get to the point where just the right hand tool is essential, let me know. I may be able to help you there.
