I start a new project by selecting a set of wood for the back, sides and top.

This is a picture of the drum sander with a side blank in it. This tool is used to gently and accurately sand the blanks to a prescribed thickness.

( 011 ) 7-March-2014

I reduce the thickness very slowly, passing the blanks through the machine several times.

( 012 ) 7-March-2014

The sides end up about 100 mils thick. 1 mil = 1/1000 inch.

( 013 ) 7-March-2014

Here the top is getting sanded to about 150 mil to start. In the end the top will end up about 100 mils thick, but there is a lot of work to do before it gets there.

( 014 ) 7-March-2014

The back blanks get the same treatment as the sides.

( 015 ) 7-March-2014

These calipers are perhaps my most useful tool in the shop. I am a measurement fanatic. I am always looking for another tool that will help me make accurate and precise measurements.

( 016 ) 7-March-2014

Here I am using the table saw to trim the edges of the top blanks. The sweet spot on these blanks are in the middle, so I need to remove the outside edges.

( 017 ) 7-March-2014

After prepping the edges so they will meet up perfectly, I use this joining table to press and glue the two halves together.

( 018 ) 7-March-2014

After the glue sets up overnight the top blank gets the guitars outline drawn on it.

( 019 ) 7-March-2014

The back blanks get assembled on the joining table with a decorative center strip.

And a close up of the center strip.
