Braces, carving and gluing

000 top preliminary carving on braces

This is the brace carving jig that holds the brace (which is just visible) and acts as a pattern for the router table


Lyndsay's guitar side.  Gluing on a patch of veneer to strengthen the area where a sound port will be carved.

Lyndsay's L-00 back with braces glued on

Gluing on the back braces for Rick's 000

This is Ricks guitar.  Dark glitter has been sprinkled on the top and then the top is subjected to a loud pure tone to see how various parts of the top are vibrating.  The glitter congregates in the vibration nodes

here is the signal generator for that drives the speaker

here you can see the top held by the area that is under the fingerboard (and will probably not make a huge impact on the sound of the guitar) suspended over a guitar amplifier that is driven by the signal generator.  This generates the chladni patterns that are hard to interprete but over time give the builder some insight into the overall resonance of the top and braces before the top is glued onto the sides.
