Here's the hollowed out one-piece mahogany back. African mahogany is fairly light to start with, but I still chambered it. I even went deeper than necessary on the pickup routes which I did before putting the top on just so I could go a little deeper. Who knows, I may end up with a neck heavy guitar?! Oh well, I'm designing on the fly...
The bulk of the wood is removed from the chambers using a drill press.
On the right is the MDF template I made and on the left is the body blank in progress. I've cleaned up the chambers using a router.
Nothing much to see on the back except the control cavity has a recess for the cover to sit in. I was able to cut the cover from a left over piece of the book matched quilted maple top.
