I radiused the back of the rim using a tool I made. One side is radiused to 15ft (back of the guitar) and 28ft (for the top) on the other side. I can use this as a template when making braces, or attach some sandpaper to it for making the rim. After that, I fit the back bracing to the kerfing, and glued the back to the rim using a bunch of clamps and some plywood scraps as cauls. Eventually I'll come up with a more elegant clamping method, but this worked out great!
I multi-tasked a lot of this project. Well glue was drying on the back, I worked on the top. I cut the soundhole out by hand and carefully used my oscillating sander to make sure it was the right size and perfectly round. Then I cut braces from quartersawn sitka spruce, radiused the X-braces and long tonebars to a 28ft radius, and glued everything to the top. The bridge plate is a piece of maple. Then I shaped all the braces using a block plane and chisel, and finished up with some sandpaper. I also signed and dated the top.
This guitar will have a bound soundhole just like the old L-0 I'm copying. I sealed the spruce with shellac, and used CA glue to glue on the white ABS binding. After this pic was taken, I scraped the binding flush with the top.
