Now it is time to cut out the sound hole.  I use a circle cutting tool with the Dremel tool to do this.

(124) August 20, 2008
The sound hole is cut out.

This guitar will have active electronics on board and will need to have a nine volt battery.  I use an end graft access system to make it easy and convenient to change the battery.

(126) August 20, 2008
I cut a rectangular hole into the end of the guitar to insert the battery.

(127) August 20, 2008
I build a battery box on the inside of the guitar to hold the battery.

(128) August 20, 2008
The battery slides into the end of the guitar, the hole will be covered with an end graft piece that is held on with magnets.

Now I am turning my attention to the braces.  Here I have laid out the Sitka Spruce brace material along with the templates that I have created.

After cutting out a brace blank I shape the bottom of the brace to the contour of the top in the top mold.

(131) August 20, 2008
Here we see the top brace blanks laid out on the top for inspection.

I use an "Engineered Bracing" system in my guitars.  The braces take on the look of aircraft braces.  Light and strong.

(133) August 20, 2008
After the holes are cut into the braces, the brace is shaped into an I beam.  Light and strong.  Get it, LIGHT AND STRONG!

(134) August 20, 2008.
Here we see the some of the top braces laid out.

Here we see the bottom braces laid out with the sides in the form on top.
