Here's a look at another guitar I've been working on.
These were taken before paint. I hope to have it painted in a week or two.

This one has two planks of maple in the middle, followed by a plank of walnut on each side, followed by ash.

It's basically wired like a Strat, except that in the middle switch position, instead of getting the middle p-up only, you get the bridge and neck.

Here's a few photos of its precursor.
This one only has 2 p-ups.
I've since softened up some of the curves on the un-painted one.

Anyhow, there ya go.
Any and all comments, critiques and questions greatly appreciated.

Awesome work, Jeff!
Do you finish the contours by hand?

Nelson,

Thanks for the comments!
Regarding the finish: I need to sand them afterwards, if that's what you mean. However, the CNC gets them pretty close to where they need to be.
I'm still experimenting with stepover distance; but I get pretty good results with a .05" stepover, using a .50" ball end mill.

I like this one even better. How do you fixture and reference the body to work on the back?

I machine "tooling holes" into the front of the guitar body, either in the bottom of the p-up pockets, on the neck, or at the bridge. I then generate some mounting blocks, and press a .25" dia dowel pin through them. I use the dowels to locate and zero, and clamp the "sandwich" together with long woodscrews.

Hope this helps.

Unique design, and good ideas on the fixturing. If you're not in a hurry to pump them out, then love thy self and get a 3/4" ball and drop down the stepover until you can get away with just rubbing off the tooling marks, though.

It might make me the laziest man alive, but if it's a personal project then I'd much rather have the Fadal run for an extra hour rather than do an extra 20 minutes of sanding :)
