So, I had these six 1x8x10' Sycamore boards stacked off by themselves in my shop. There has been alot of clutter around them for about a year so I didn't notice them twisting. I was cleaning up around them today and found that they had curves and crooks in them that would make a snake jealous.
Now the question is, are they any good for firewood or maybe kindling? That will be the last resort before I throw them on the waste burn pile.
The only bright side is they were bandsaw milled lumber so I'm only out 25 cents a board foot. The rest of the Sycamore cut that day was stacked under a load of Oak and still appears to be straight.
