My next uke will be a custom shaped baritone inspired by the Gibson L1 shape. I have the molds and spreaders ready to go. Should be fun!

I ripped off the LMI design for the outside mold.

Good question. I have a thought about mahogany and spruce combo given the L1 influence.

I also have a neat set of Koa that has some sapwood on the back that is big enough.

Any recommendations?

Very nice! CNC sure makes it nice for cutting jigs and fixtures like those that actually match up perfectly in shape.

I'd second the vote for koa....

Indeed. It scratches the part of my brain that wants everything to nest together perfectly. The side bending form is -.082 to account for the slat and side thickness (I bend with blanket on top) and then the lining bending form is -.262 to account for the lining thickness (.180) plus the side and slat (.082). Russian nesting dolls. :)

Russian nesting dolls. Ha! For me, CNC was sort of the logical outcome of my life in IT/Electronics/Motion Control Systems/Woodworking/Instrument making. Combines my inner geek with my other interests and/or talents. At first, I felt a little guilty at having yet another computer located in my shop. I got over it. My shop PC still runs stripped down XP completely off line. I do have a nice industrial touch screen monitor to control the CNC though (UCCNC). I still do my instrument building using mostly hand tools, but I rough out archtops using CNC instead of router jigs nowadays as well as slotting/arching/scalloping fretboards. Jigs and fixtures too.

The handwork is still the most satisfying, but since I've retired I still like to keep my geek skills up to speed too.
