Ah, you have a good one. My cheapie only goes down to 6%, and I wouldn't trust it as more than an approximate indicator. But then, I'd only dry timber to 5-6% if it were to be used in an airconditioned environment. For normal domestic use, drying to around 12%, then stabilising in a good approximation of the final use conditions (as I figure you're doing - with dramatic results) is what I'm more used to. If the board ends are uncoated, they'll dry ten times faster than the middle, rather like you're finding with the surface. I've found 8% higher MC in the middle, c.f. the surface, on partly dried 2" thick wood. Rather than wreck the probes by banging them in, I prefer to drill a couple of good sized holes halfway through, then lightly prod the bottom of them, or just split an offcut with a chisel. Since the boards appear to be way wetter than they'll ever be in later use, a lot of expansion room in the breadboard slot doesn't seem to be called for - they're only going to shrink from the status quo. My worry would be the width of the slot tracking board tenon thickness as everything shrinks. (It's nicest when breadboard ends don't rattle.) Best of luck. (As I figure the plan is to plough on, rather than stop to (kiln) dry the wood first - if it's even dry enough to start that.)
