Got the top jointed a glued up.

Finished thicknessing the body and then routed all the straight bits with a straight piece of MDF. Then I cleaned up the corners and the heel with the spindle sander. This thing is still 5 or 6lbs.

Which brings me to what I'm planning to do for chambering. 1/2" walls, 3 1/2" center block, lower bass side wing completely hollow aside from a spot for the strap button, upper bass side solid since I have a feeling I'd screw up and carve the rear contour into the chamber, and then hollowed out the treble side aside from a spot for the heel access contour. Next step is to make some templates, hog most of it out with a forstner bit, and then get back to routing. I'm curious to see how much weight it actually loses.

When I got to the 24th fret markers the awl chipped out a piece. I've spent an hour looking for it and I'm currently taking a break. My basement must be a pathway to another dimension. If I can find it I can just glue it back on. If not I'm not really sure. I know it's there somewhere.
How did you fix the tearout? You could just sand it flat, glue on a piece of Ebony and saw/sand it flat to the fretboard sides.

Honestly that shit pissed me off so much that I haven’t tried to do anything with it yet. I’ve thought about cutting and grafting a piece in which would be tricky. Maybe making it 22 frets which would take care of most of it.

Finished making templates for the weight relief chambers. The round parts are for the heel contour on the big one and the strap button on the smaller one.

Then I started hogging out a bunch of the wood with forstner bits. I'm doing this with a hand drill very carefully, but man is it tiring after awhile. I didn't drill to final depth just to make extra sure I didn't drill too deep. It's getting a bit late for power tools and the vacuum so I'll be continuing this tomorrow.

Don't think that's necessary. Sand away as little material as possible so you get straight edges on the two outer sides. Using a dark or transparent glue will make the joint line almost invisible if the wood piece is halfway similar. The more I look at it, the more I think it should work.

I think I understand what you’re saying. I’ll take a few pictures of it later when I get up and get to working on I m it.

Got the top rough cut out and then out came the clamps. There's about an 1/8" overhang that I'll spindle sand as close as I can and then route to the rest of the body. Then the next step will be routing for binding. I've never done it before, so it will be a bit of an experiment, but I have all the Amana rabbet bits with the various bearings. I'll be doing several tests before I hit the body with them.

Here are those pictures I'd said I'd get this morning while I was still half asleep. I moved everything in my basement/workshop and couldn't find the piece anywhere. I'm sure it will pop up eventually. The easier fix would be to make it 22 frets. There would still be a chip out, but it would be a lot smaller. The more difficult fix would be to sharpen my chisels and use them and a small pull saw to cut out a square piece and then cut and glue a new piece in.

Using a chisel to create a rectangular cutout sounds like a lot of trouble for this little issue. Sand it to a sloped surface and glue on a piece of the original fretboard wood. File and sand down the overhangs or use a kugihiki (if you have one).

Dude thank you for the illustration. That is a much simpler approach than what I was thinking. I just ordered one of those saws since most of my pull saws are huge. I should have some scrap ziricote around somewhere.

Hope it works out. And everyone needs a Kugihiki, super useful for a lot of tasks when building guitars.

The clamps came off and then I sanded and then routed the top to the body. All those corners were tricky with the handheld router. At least with this I can sand out minor imperfections, but not so much with the binding routes. I was planning on doing two passes around the body. The first one with a larger bearing for a smaller cut and then the actual bearing. It looks good without binding, but the black limba star is going to get black binding so I wanted to practice.

Plus a little mockup with the neck. It still has the 7 string sized headstock, so that will be a bit smaller. I just need to thin the bass side of the heel a bit so it's flush with the neck.

I filed and sanded the fretboard. Now the tricky part is figuring out how to clamp at a weird angle like that. I may need to cut a small triangle to get a flat surface.

You could try wrapping an elastic masking tape around the fretboard with the new wood piece. What also helps stopping the wood from sliding around is a tiiiny pinch of salt.

Probably could have gone for an easier shape with my first attempt at binding. It’s a little tall so I’m going to have a lot of scraping to do.

It looks like that worked. I'm currently filling in the gap on the side with some ziricote dust and CA glue. Hopefully that covers the wood glue, but if not I can figure something out.

I used a little bit of salt, some tape to hold it in place while I got it clamped, and then used my new kugihiki.
