Gluing the X-braces

Well I got a little more work done on the top plate. I left off last time with just the x-braces glued on after shaping them. I also pre-shaped the tone braces.

In the next step I glued up the rest of the braces and did some final shaping. On this guitar I am using scalloped braces as opposed to non-scalloped. Scalloped braces offer a little more vibration in the top plate given more overall volume. Non-scalloped give a more even, balanced range between the highs and lows. The scalloped style is more common with the vintage guitars. Finger picking guitarists tend to prefer the scalloped bracing for its range and volume.

Gluing on the six tone braces. Notice they are notched in under the x-braces for added structural strength.

The bracing around the sound hole. These are only 2mm thick.

I then drilled a hole in the brace for the upper bout for access to the truss rod and then glued it on flat. This brace is not arched. The top plate will transition from a dome to flat in the upper section. Some do this and other don’t. I am trying it this way to make the finger board, which extends down past the 14th fret easier to attach to the sound board. I also glued on the bridge patch, which protects the top plate from the guitar string ends digging in under tension. I used some 2mm quatersawn ebony.

Finally I took a scraper and rounded off the edges, did some hand sanding and added a half-lap top crown on the x-brace intersection.

When I do some tapping on the sound board it has a nice tone. I am not sure what to listen for as I have no experience here but I can say I hear the wood singing. That is to say there is a resonant tone.

This sound board is finished. Next I will move on to the back.
