Back in the '70's, I did have a dust doodler as the locals call them. Chain with no paddles on the Corley mongrel mill I bought and had to completely rebuild. Second Corley had the blower.
Sold the slabs to the local charcoal kiln and cut some up to sell to locals for stove wood. We burnd slabs as long as we had a mill to cut them to keep our homes warm. 98% of what we cut was hardwood, Red and White Oak, Post Oak, hackberry, all sorts of Hickory, elm, Ash, etc.
