This photo gives an idea of how the curved bracing scheme is going to work. The braces are 1/4" wide by 1/2" high. They still need to be trimmed to length, notched, and contoured.
As previously noted, this scheme is derived by Gibson's bracing pattern on the L1, except Gibson used straight braces, and they weren't notched together. The two long braces in the photo were, on the L1, in two pieces that butted against the either side of the brace just below the sound hole at the points labeled "Notch" in the photo.

Braces bent for top

Very interesting bracing scheme. I bet you get a really nice bass response!

Shaping the back braces
I glued on the back braces using hot hide glue. I didn't get good clamping on one of them so I had to re-do it. The end of another wasn't fully down, either, so I had to fix that. I'm still learning how to handle hhg. TiteBond is definitely easier!
I'm shaping the braces now. The thing to the left is my leather sharpening strop.

Re: Braces bent for top
Cool bracing scheme, I can not tell in the picture but I would make sure the corners or edge of the bridge are on the vertical curved braces.MaineGeezer wrote:This photo gives an idea of how the curved bracing scheme is going to work.

Re: Cherry parlor guitar, project #2
That's the plan; the idea is that the rotating torque on the bridge gets transferred to the long braces. The curve of the braces helps dissipate the load, and the cross brace below the sound hole that the long braces are notched into further dissipates the torque and shunts it to the sides. The bridge plate will be fitted snugly between the long braces and have curved edges so there aren't straight line stress concentrators.
Here's a photo of a reject bridge plate that was intended for another guitar, that gives the general idea. This on ehas a bevel to fit aganst the tone bar, but on the guitar I'm building I think the bridge will be far enough forward so the bridge plate won't intrude on the tone bar.

Gluing on the kerfing
Gluing on the last of the kerfing. I'm trying reverse kerfing this time. It does make the sides considerably stiffer than conventional kerfing does.

Hahahaha!!!
Your cat looks identical to my Marlow. I lost Marlow a year ago. I have to watch, otherwise my other guys will lay right down into the open box.

Re:Profiling the top braces
Profiling curved braces is a bit of a pain. They're coming along though.

Re: Cherry parlor guitar, project #2
I like the bracing. Can't wait till it comes together and you get to hear it.
