There’s a local sawmill that deals mostly in Pine but does Red Oak on occasion. They toss all oak scrap, a combination of 4x4 and 6x4 ends about 12” long and 1” thick slab pieces from squaring the logs, onto a pile half the size of a tennis court and sell it for $20 a truck load.
3 years ago I hauled out 22 truck loads over the spring and summer and have just about gone through it all. It’s been a nice supplement to the Locust, Apple and White Oak harvested from blow-downs on my neighbor’s property.
I made a 3 inch diameter candlestick in my first wood turning class. It was made out of a short wet Apple log. I was shooting curls over my shoulder in no time. One of the funnest things I’ve ever done in my life. It was legal too, lol.
