I came across a board of White Oak that was nicely quarter sawn, had good figure, and was 8/4 (8 quarters of an inch = 2") thick.

What to do, what to do?

Resaw it into guitar wood, THAT's what! I managed to get 7 sets of sides and six sets of backs. Now I put it away and wait till I have a project for it. Every luthier builds a stash of wood, the best way to do it without breaking the bank is to take advantage of opportunities when the present themselves.
