Pine Boards with a Chainsaw Mill

A chainsaw mill is a frame that holds the saw's bar flat at a set height, so the chain rips a log lengthways into boards. The first cut rides on a straight board screwed to the log; every later cut rides on the flat face before it. The green boards are then stacked on stickers to air-dry. Pine dries fast: a 25 mm board can reach about 14 % moisture in 60 to 90 days in good drying weather. Oak and other slow species take far longer.
