We tend to think of air dried wood but water cured is much better. When green wood is left submerged for a long time it cures far better than air drying, few , if any, cracks or checks develop. This allows much wider boards to be cut. Even a wood kiln does not use air. It uses steam. Of course, this is green wood, I'm not sure about wood that has already been air dried. Water is not necessarily the enemy of wood. Here is something I got from a quick Google: http://www.latimes.com/nation/la-na-sinker-wood-20140713-sto ry.html This is more common than you might think. Apparently the state of Oregon has outlawed the harvesting of underwater timber. https://www.npr.org/templates/story/story.php?storyId=3D126319 923 Allen -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of John Gardner Sent: Monday, February 19, 2018 11:47 AM To: Microcontroller discussion list - Public.
