I've warmed up to many barrels of burning lumber on a construction
site. Kept warm. Even when I had a wood burning stove inside at home
I used remnants of lumber.
"My doctor says I have a malformed public-duty gland
and a natural deficiency in moral fiber, and that I am therefore
excused from saving Universes."
Construction lumber is not all that dry. IIRC, it is about 12% compared to
the furniture grades that are 7%. Most will twist and bend once brought
into the house. I've seen it at the store with as much as a 90 degree bend
in it. Incredible how bad it can be.
One wouldn't think so but it does. I built a temp wall to hold up the
ceiling while I was working replacing the roof (rafters and all). Put
it up one day, next day one of the studs had a 90 degree twist in it.
That was lumber fresh from the lumber yard.
Clamping or weighting it will only hold it until you remove the clamps.
As for kiln dried, you would have to buy direct from the saw mill to
get any that wasn't kiln dried. At least in this part of the country.
I believe lumber from any source that spends 5 weeks flat on a basement
floor is likely absorb and release moisture unevenly and thereby warp. It is
best to use it promptly but if not it needs to be stored so that air can
circulate evenly around it.
Is this clear lumber (non-treated), or is it treated?
I have piles of lumber that often sit outdoors for while when I tear
down a building. Aside from an occasional board, I rarely get warped
boards. On the other hand green treated tends to warp all over the
place as it dries. Its always wet or damp when I buy it, and it warps
like crazy upon drying. So, I assume you got treated, or else your
basement flooded when no one was looking.
Of course if you bought cottonwood lumber, then it probably is
firewood. I bought some rough sawn cottonwood 2x4s from a local
sawmill. They were cheaper than pine, supposed to be stronger, and I
figured for the barn roof they would be fine. I picked straight ones,
when I finally built the roof a month or more later, these were so
twisted they were unusable. They got rained one once but were kept
inside after that. I'd never buy that junk again, and since the guy
at the mill would not take them back, he lost a customer over $40.
:I made a grave error recently. I bought a lot of 2 X 4s to finish off
:my basement. Unfortunately, I couldn't get to it right away, and the
:lumber sat on the floor of my basement for about 5 weeks. Well, when I
:bought the wood, I selected each piece for straightness. Guess what?
:About 2/3s of them are all twisted and bent out of shape - useless
:except for starting a fire in my fireplace.
:So, don't be like me. Buy your wood just prior to using it. If not,
:you may end up wasting a lot of money.
Not to denigrate your post, but I haven't experienced this. I've often
bought wood and put off usage and can't recall regretting it. I HAVE
experienced wood warping, but resolved the problem by stressing it in
the opposite direction for a short period, straightening it out.
