It'll do...
I bent up some strips, and glued them one at a time into the sound-hole...
Not a perfect circle, it's bad enough using a handheld drill with a wing-cutter, but as I mentioned before, my bench-top drill press has a very shallow throat...Did the best I could sanding the damage back into usable shape...Hillbilly style
Then I glued up some of the scraps from the ring bending session...
I was not planning on having the fretboard stretch all the way to the sound-hole which would normally cover the gap. And since I've already rough cut the neck/fretboard to length, I chiseled out a spot to hide the end gaps of the rings, and cut a piece to finish her off... Aw well, beats starting over...I did say prototype right?
I also added a backer piece around the rings for good measure, going to sand it down a tad more when I get the braces shaped, which is the only other thing I accomplished on this today...
A learning as I go...will post more when there's something to show
