Just took a quick and very bad snapshot of the full-size drawing of a work-in progress. I'll get some better pictures in weeks to come.

Basic idea is a small - approximately "00" size, though the shape is my own - ladder-braced guitar using ideas from the Waterloo, John How, Stella, Schmidt, and advice from people I trust.

-3 braces for both top and bottom.
-Lower bout top brace will not engage the kerfing, to free up the top a bit; also, the lower bout perimeter will be thinned to .060"-.070" depending on how it feels and taps.
-Offset soundhole. Debatable (like everything), but I think the reasoning is sound for a LB guitar - this will help prevent the 'potato-chipping' that is endemic to LB instruments; and as well gives additional wood right in the center of the instrument, where it can add to the sound.

-14-fret; 1.75" nut; 2 3/8" pin spacing on bridge; saddle slot at 8 degrees; solid mahogany neck.
-semi-cutaway - just a matter of taste plus, I want to use the shape as a 12 fretter also and then the cutaway would add functionality.
-solid linings
-solid Cherry back; double Cherry sides; Bearclaw Sitka top and Sitka bracing. Fairly minimal appointments, though I have a bridge shape I copied from a set of plans for an old old Washburn - like 1930's - and a headstock shape that provides almost straight tuning-peg to nut slot lines.
I have hopes for a comfortable, loud, sweet-to-growling little cannon. We shall see!!

One thing not shown on the drawing is the A-frame in the upper bout - idea from Lowden. I've used this before.

This project has great potential to produce a significant improvement in the basic ladder braced design.

One can hope. First. I just don't want to embarrass myself, of course. ;-)

JOhn L - thanks for all the encouragement as we discussed this project.

Various pix - the tonewoods I'll be using, the fb and bridge material, laying out the rim contour, the cat who has been a PITA today, my favorite pencil sharpener (!) etc. Nothing new here for most of us.

Wish I could let a kitty into my shop, but it's in the basement and the little hunter might not come out for a week, and there would be no going in and fetching him/her (one of each).

I'd love the company.

Well Peter, after today's performance, I could loan you mine for awhile. ;-)
Anywhere my hands went, she immediately followed and stuck her head in the way. Sure, I scratched her and scratched and scratched...but she is so d*** persistent!!!!!! Normally she's very good company and at least laughs at my jokes.....

A couple of things accomplished today.
Thankfully the cat was in a better mood. And asleep.
Got the bridge finished up, right at 30 grams or so and that's without the pegholes being cut.
Made a template for the cutaway - tomorrow will make the 6-layer glue-up, to be used for bending and for building.
