This week, and probably next week, will be spent mainly on constructing and finishing the front braces. The theory behind it is fairly complicated but really revolves around two main points.
- Support: The strings will exert about 180lbs of force on the middle of a spruce top which is 2.4mm thick. To give you some perspective, I could easily snap the guitar top with my two hands and minimal force. The entire top weighs perhaps a couple of ounces.
- Sound: The top basically operates as an air pump. As the strings are picked or strummed, the energy will be transferred to the bridge and then to the bracing which in turn will transfer the energy to the top of the guitar.
