It started when I ordered several sitka spruce wood for ukulele tops. It came a little too thick, which is about 5mm and needed to be reduced to about 1.8mm in thickness.
Instead of using a thicknesser to bring down the thickness thought, we would use a router to thin it down but leave some parts to the original thickness where braces, bridge plate, rosette, neck block and end block would be glued on. This would make the sound board stronger. But first things first, we would have to make a template for the router.
After routing, the result is as shown in the photo below.
