Here we see the two halves of the top after they have been glued together.  I have drawn the outline of the guitar on the top to make sure everything will fit. At this point in the process the top is about 150 mills thick. If you look closely at the top and the bottom of the joined pieces you will notice they are very slightly offset.  I do this so I can easily find the joint line.

I spend a fair bit of effort on making the joint line of the two halves all but invisible.  This picture is a closeup of the two joined halves.  You can find the joint line in this picture by following the growth rings to where they end in the middle of the picture.

Now I have turned my attention to the sides.  In this picture I am using my drum sander to reduce the thickness of the sides to 100 mils.  I slowly reduce the thickness by repeatedly running the sides through the sander raising the platen about 5 mils each time.

After the sides have been sanded to 100 mils thickness I use these templates to draw the outline on the wood.  I am careful to line up the figure on the two halves so they will match when the guitar is assembled.
