At a park just a few blocks from Core's NYC offices, city workers have cut down a large tree and left it lying there in large chunks of trunk. As someone who has to save up to buy wood for DIY projects, it's killing me that I can't just rent a U-Haul, press some friends into service, and take the wood somewhere to get cut; I've no idea where the nearest saw mill is.
If you've ever wondered how they turn trees into boards, check out this video of the Jackson Lumber Harvester 3 Saw Vertical Edger. Take a look at the size of the main blade, and check out the nifty side-saw action!
Here's an older saw mill, where the operator(s) have to ride on the sled, instead of being tucked away in a DJ-like booth.
Lastly, here's just about the greenest saw mill you'll ever see: A hydro-powered saw mill, one of only five left in Norway. First introduced around 1520 by German engineers, the saw uses a waterwheel to power both the blade and the log advancement.
