Yesterday morning, before the rain started, Lori and I started laying down the decking. Made an interesting discovery: Dimension lumber is no longer any such thing. I wanted to shim these boards pretty tight to prevent things from falling between the cracks. However, this was made nearly impossible because some of the "2 by 4s" are not the expected 3-1/2" wide! Some of them were off a full 1/8"!! This, I have to say, is my first encounter with this deal. The question formed in my mind, "How hard is it for a mill to set their equipment to 3-1/2" and leave it there, & maybe check it every once in a while? Is that asking too much? Anyway, we expect to finish this tomorrow, weather permitting.
