Hey Rand. Nope, the seam was joined with wood glue. As I mentioned the only thing I use superglue for on my builds is to attach the bone nut to the neck. The only reason I used any here was because I was in a hurry to play the guitar!<br />
I was very happy with the join on the soundboard. You literally have to get right up close to see it. As MFJ said - I'll maybe start taking more material off the neck recess to make room for the bracing.

<p>Re-reading this thread, I wonder if the fault could be in the seam where the two halves of the sound board are glued together. Were the two halves of the soundboard joined using superglue? Perhaps (as Michael Fred Johnson has suggested), by adding a brace down the middle of the box to reinforce this seam would help to eliminate the warbling distortion effect.</p>

<p>I had neglected to consider this on my original analysis of the problem likely because I seldom build my sound boards by joining the two halves (as some builders do with great effect when using book matched pairs of boards cut from the same piece of nicely grained lumber).</p>

<p>Hi Michael,</p>
<p>That's a nice design there. One of these days I should start experimenting with internal bracing. But, to this point, I don't make very wide sound boxes and the material I use for the sound board and backboard is 2mm thick plywood veneer. The sound boards I make also are one piece and so may not need as much bracing as a sound board made of two (or more) butt joined pieces of wood.</p>

<p>Also, I like a slender (not so wide) sound box because they are easier to hold on to with your remaining fingers while you pick or strum the instrument. Of course, any educated player probably would object to my playing style. I usually play 3-string diatonic stick dulcimers and tend to play simple tunes by down picking with my thumb. Holding on to the sound box probably is a bad habit that will ultimately limit my growth as a musician. After all, that's what guitar straps were invented for.</p>
<p>Your boxes are always so well crafted. Keep the photos and ideas coming.</p>

Thanks Michael. this kind of bracing certainly looks much better. My only issue is that I use a 'neck through' design, so there is only approx 2 mm gap between the bottom of the soundboard and the neck, hence the odd shape of my braces.<br />
<br />
I noticed earlier that the brace at the back is not underneath the bridge. for this box I will try adding 2 more braces the same as the ones already there. My reasoning is that if it working fine before, I should be able to correct it.

OK - update... I've managed to cut the soundboard off with no damage to either part using only a small craft knife and some skill.<br />
<br />
Now where's my superglue?<br />

I'll let you know how the re-bracing goes. Thanks all!
