I came into three 8/4 walnut slabs today. Moisture meter reads 30%. How long can i expect it to take to get,to 10% or so if I stick stack them outdoors? I am going to see if there is a local kiln service, but I suspect they may want more than the $1.50/bf I paid for this. Like to work these before I forget why I bought them 😜
TWO things:
It all depends on where you live as to how dry they will get. I live in the southern half of Alabama and two stacks of oak (red and white) have been air drying for nearly a year. I just checked them with my moisture meter a couple of days ago - 14% I then checked a kiln dried 2x4 near them, - 14% As I said, "It all depends on where you live."
"It all depends on where you live."
IIRC the number I got for my area (Western NY) was 17%. Meaning you'll never
get wood stored outside below 17% no natter how long you let it sit.
If I used the average annual temp and humidity from the following document,
~14% is the best I could do. I know it doesn't work like that, but the point
is, I'd never reach 10% - at least not on the way down. ;-)
