I likely have about 100 bf each of red oak, poplar, Sycamore and ash mostly 3/4-7/8" with some 1/4 _ 1/2". Also have some maple, walnut, cherry, hickory and Allen. Then I have a bunch of exotics that are generally 12-24" long.
I am very fortunate to have the stock of wood. We are blessed in the Midwest to have lots of different hardwoods at reasonable prices. I typically go up to a small sawmill in Michigan to get hardwood when I need it. My wife likes to go as we go by several wineries nearby.
