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.

Pick and prop the log
Pick and prop the log
Choose a straight pine log, 2.5–3 m long, without large knots. Prop it on two short logs so it cannot roll and the chain will not reach the ground.

After 2 months, read a board from the middle of the stack. Air-dry outdoors reaches about 12–15 %; bring boards for furniture indoors to settle at 6–8 % before working them.
