If there's anyone left here for whom wood (from a tree, I mean; which reminds me: anyone know if Super Gay is doing OK?) brings on wood then you'll appreciate my ecstasy at finding a trove of clean hardwood pallets. Red, white, and (I believe) black oak, hard maple, beech, birch, and ash. All just a bit too wet for furniture, but close enough that a DIY dehumidifier kiln will turn this into the raw material for counter tops, a proper woodworker's bench, horse for draw knives, etc. Yes, very stoked.
Interesting. I'd like to see it. My dad has been chasing down trees and having them sawed into planks. He's been stickering them and waiting for them to dry, but this might speed the process. I've found some sizeable pieces of lilac and rosebud, which might make some interesting small projects, but the pieces are too small to treat like larger lumber. I was thinking of kiln drying them in the oven, but this might work too.
Based upon what I've read a standard household oven may not be practical because it will either dry the material too fast and so it will check OR it will take too long (weeks, if you dial down the temperature) that it will just piss you off ("we cannot have fish sticks for dinner because the oven is loaded with WHAT?!?!"). Selfishly I say: try the oven, and then report back because I'd like to know if it can be done.
Air-drying may or may not be appropriate depending upon the kinds of projects that you guys have in mind. Based upon what I've read wood for interior projects should be at or below 8% moisture content (Harbor Freight has a $13 meter that the online hobbyist community seems to like), but air-drying will get you only as far as somewhere in the teens. I had been thinking "oh bullshit" about the need to fall beneath a certain moisture threshold -lot's of antique wood structures and wood furniture in museums, all presumably constructed of air-dried lumber- but I've read that kilns have been in used for over 100 years and then for every Chippendale highboy at DuMochelle there are probably 10,000 other contemporary pieces that twisted their way into firewood.
I've air-dried silver maple, sycamore, and apple (one year per inch of thickness) with good results, but so far I've only used the material for small projects. Some say that air-dried or slightly wetter wood responds better to hand tools than does kiln-dried; difficult for me to say if there's a difference because the only silver maple that I've used is this home-grown stuff.
There's a lot online about home-processing lumber, and it's from there that I've gained my education. My plan is inspired by what I've read, but with the unique twist that that it can be knocked down and then stored flat, i.e. suspended as a stack of pieces from the ceiling of the garage when not in use.
