Construction is not really all that dry (seasoned).
I will be very interested in how that stands up after is "really" dries out.
I generally have not had good luck with that.
Leo, there is a trick to it. "white" pine lumber dries very, very fast, especially if one stands it out in the NC sun several days in a row. That is how I start it out. Because construction lumber is so cheap I buy quite a bit at a time. After it has been out in the sun for a few days I move it into the air conditioned shop. The other thing I have been doing is cutting pieces to a rough length. Since it is so cheap I am not worried if I create some scrap. At $1.00 per bf a person can try things.
Another "trick" I use is to cut between most knots, so when I am picking it out at the store I pay attention to the spacing between knots. I generally look for about 2 feet between knots, more or less.
And THEN. . . they do not sell "white" pine wider than 2 X 6 in this neck of the woods. Wider boards are all SYP. Not so good unless one is willing to wait much longer for them to dry. So when I am visiting the brother and sister in law north of here I buy some decent 2X12's which have way fewer knots and haul them back.
BTW, one normally gets in trouble with pine when building something like furniture with it when it is too wet. Of course the same is true for any lumber. But a glued up flat panel that has no constraints on it has no reason to come apart, what it can and will do is warp.
I have a yard sign I made five years ago that hangs on our fence that is about 2 foot square using the same technique. Other than needing a repainting it is just fine. Just think, this sign gets baked, and I mean BAKED, in the NC sun and then gets drenched in our rain storms.
Here is a thought, give it a try, it will cost you all of about five and a half bucks in lumber! (Use water proof glue if it goes outside)
