Thanks guys.
You'll notice that the waist on these is higher than the OM effectively
providing a bit more real estate south of the bridge. Reason for this was the theory that most of the sound is coming from the lower bout.
The upper bout is very small and should be stiff, giving some more support to the neck block to accomodate the extra tension of a twelve string.
The whole body shape is small so it should be possible to build the soundboard lighter and stiffer than on a larger guitar.
On the guitar pictured with the OM the soundhole is also shifted a quarter of an inch towards the neck thus the X brace will be forward shifted and the fingerboard will be a 19 fretter.
The braces on this one are 8mm wide (typical dreadnaught/large guitar width braces) size and scalloped.
The body depth is 4 5/8 at the end block and 3 7/8 at the neck block.
The top is Adi which is 2.8mm thick in the middle thinned down to 2.5mm at the perimeter.
So there's a fair bit of experimentation going on and I don't really know what it's going to turn out like.
What I am looking forward to is making assessments when it it is finished and fine tune any further ones like this to eventually come up with something that is our own shape and sound.
I'm sure someone like Al Carruth would already have a lot of these answers at his fingertips.
Cheers
