Post subject:  Latest build: Headless 8 string
Comments and suggestions welcome as always.

The Good:
Neck: maple
Fretboard: ebony
Truss rod: 2x carbon fiber spar only
Neck joint: bolt-on butt joint
Back and sides: magnetic pine
Top: Spruce
Electronics: Radio shack piezo buzzer
Scale lengths: 23.5" and 25"
Binding: rosewood
Finsh: wipe on poly

The bad:
1 Somehow the sides shifted in the mold when gluing the top which ended up slightly altering the shape and also altering the angle of the tuner slots at the bottom. I suppose I should have kept bending the sides until they sat in the mold without any spring.

2 It seems the sound hole corner was a little too much of an angle for the 1/8 inch rosewood binding, and it split.

3 A part of the binding moved while I was gluing it, so it dried sitting 1/8 over the bottom of the slot.

4 Both the top and bottom have a small crack. On the top this is due to the headless tuner section being a hair too tall I think. On the back, as soon as I planed the glued pine slats, they started cupping on me. I wrestled them down and glued them to the brace, but I think it eventually caused the crack.

Since I am working under a lot of limitations (no bandsaw, no thickness sandler) these pine slats are really handy. They come around 2.25" x .25
" x however long, which is kind of cool, if I ever wanted to build something big. I just glue the slats side by side, taking care to keep the correct orientation. I will say that these glued pieces are extremely hard for me to plane. Not sure why. Seems difficult to find a good direction for planing.

The Ugly:
I don't need no stinkin' transverse brace.
Uh, maybe I do.

Once I brought the strings up to tension I let it sit for a day. I noticed the neck move, about 4mm forward at the nut. I re-shimmed the neck and went thru this cycle several times. The top is definitely caving a little near the neck. Since I made some generous access panels on the back, I am hoping to add a brace. I don't mind compromising on a lot of things. But the action has to be low for my personal taste. I like it when people pick up my creations and say "At least the action is great."

Making an 8 string travel guitar is kind of a contradiction. A small body is going to be light, which will be a problem when you stick 8 tuning machines way out there on the headstock. This is one case where being headless definitely helps.

I definitely have some artifacts due to break angle, I can hear that phasing sound.

Most of the video was recorded with the mic, not the pickup.

Man, that is one of the coolest things I've seen!
It sounds great, and I really enjoyed the video.
I like your dowel form!
You have a gift for designing and building with available materials and tools.
Well done!

Very nicely done! I'm glad to see that the fear of being different has not affected this community... :lol:
