      If you have any micro scaled pieces of madrone burl give me a shout out. People who make miniature scaled furniture are wanting to buy it.

Stacked the wood wood on a pallet, put a pallet on top and used cargo strapping to supply pressure to keep the Apple from bending. I left one piece out. During the drying process it got 30 degrees of twist and about 20 degrees of bend. So I know the Apple that dried under pressure has a LOT of tension in it.
      > This winter I again cut a bunch more Madrone Burl, this still mills (or turns) like butter, but splits if you look at it too fast. The cure for this (and some other easy-to-split woods) is boiling. Yup, boil the wood for about an hour per inch of thickness. The failure rate, after boiling, is, well, very low. No one (including Forest Product types) knows -exactly- why this works, but it does appear to relax/release/something a lot of the tension in wood, with greatly reduced splitting.
      > I have also processed, well maybe tons of green/wet Maple, Red Alder, Walnut, Butternut, Filbert, Cherry (timber), etc. This wood has been mostly used for turning. Some of the bowls I turn green and let dry, some I rough turn green, dry, and re-turn, and some I have let dry then turn. Some of this splits, but as some great turners say "There is no turning that is so bad it can't be used as firewood"
      > But one other thing I do is Microwave dry wood. Yup, get ahold of one of those old LARGE capacity microwaves that everyone used to own and dry wood that way. Depending on how much wood is actually in the oven the cycle might be as low as 30 seconds, or as high as two or three minutes. Let it sit for maybe an hour, and repeat. I weigh the wood just before I do a daily cycle. When the wood stops changing weight, I stop.
      > One other thing on checking woods wetness. There is a pencil that many art supply houses sells called "ink in a pencil". On dry wood, it's just a pencil, but if the surface is wet, the pencil "lead" turns blue and stains the wood a bit. When the pencil mark doesn't turn blue, the wood is getting dry
