Ron's illustrations are excellent educational tools clearly showing the physical differences between the three types of lumber "cuts" available, quarter, flat and rift sawn. Yesterday Chuck mentioned that anything but quarter sawn wood is less than ideal for ukulele / guitar / (stringed instrument) construction because quarter sawn shrinks the least. I was wondering if anyone else could offer info on the use of the different types of cuts. Also, what happens when a glued back/top shrinks? Is that how cracks develop in the older ukes we see available? Seems you can't find an old Martin without some crack in it somewhere.
