Thanks Kevin!

I have gotten a lot better cutting pearl and the ebony since that first time when it seemed nearly impossible. This time the fit was perfect with no need to pull out my needle files or fill. Over the years I picked up a few things that help. I hold the saw loosely and never try to push it forward. This helps maintain the plane of the saw. I also make sure I can see what I need to do. I have started to just watch the line I need to cut instead of trying to cut on the line. It sounds weird but if you are walking down a path you do not think about what your legs are doing or think about turning right or left you just walk and follow the path. I get that way while I am cutting; the saw goes up and down and the cut follows the line. I do slow down when I need to make a right angle turn.

... and do not BBQ the hawk. It is cool that you got a close up photo.

I have been nervously waiting but I can not rush the finish process. I used zpoxy - EM6000 wb finish on the body and CA and Royal Lac on the neck. I am just a couple of days from being able to sand and buff out the guitar.

It still needs a setup and the final polishing, but here it is with strings. The top resonance came out lower than I thought at 175Hz but the bridge rotation while not measured looks OK. The height of the two main falcate braces were at 10.5 mm around the bridge; 3.5 mm higher than might last SS that ended up with a 170 Hz top resonance. As a further note I used the same vibrational stiffness value in Gore\Gilet equ. 4.5-7 and the secondary braces were kept the same at 7 mm. The back may be at 233 Hz, the back was heavy so I did not brace it as an active back.

If it holds together it has a very loud and rich sound.

John, I know you have probably mentioned it before, but what spectrum analyzer are you using there? Another beautiful guitar by the way.
