I got a couple of maple 4x4's a while back from a Maine mill that
specializes in figured maple and uses vacuum kilns. Four days to low
equlilibrium. Nice stuff but the inside is full of honeycomb from too fast
a drying time. I question if it was caused by rapic water loss or by
stresses in the wood. Likely both?

Stress caused by too-rapid loss. Makes it difficult to get even drying. The
moisture takes the easy way out and leaves shrunken fiber, while other, less
accessible places are still expanded.

Haste makes waste?
