A simple approach to drying lumber - Woodshop News

Aug 27, 2008· I get my sticks from a mill that stacks their lumber in 6' wide packs, and I take the broken sticks they can no longer use and cut them down to the 4' lengths I use. You do get lower-grade material from your logs that you can turn into sticks, and you can always cut the material from logs that you don't value as highly, such as beech or ash.
