gregmary,
Your process for machining the body is nearly what I have planned for my LP.
I will forgo the scroll or band saw though and let the router cut the profile of the body. by leaving three tabs in place the body will not move from our fixture position and they can then easily be trimmed off. I am trying to achive the light weight guitar but with an entirely different approach. I am using a combination of obeche, balsa and carbon fiber composite. I am doing a double cut. If I can help in any way let me know.
