2x wood quality depends on location, and luck
wilbur
>I've been checking out more home centers in my area over this weekend. It does look like location and luck have a bit to do with what you'll find.
Again, I'm in central NJ, and all of the 2x material seems to be Douglas fir or kiln-dried SPF 2x4's. I haven't found KD-SPF in any other sizes.
I found that one of the local Home Depots carries untreated 4x4x8 Douglas fir beams that can yield good results -- I found two beams with at least a 6' span of knot free wood, which I grabbed. But most of the Home Depots around here don't carry this stuff.
I stopped into the Lowes in my town as well, and found that they must have gotten a delivery of 2x10 and 2x12 Douglas fir that was of much higher quality than I had seen before. Up to now, I had planned on taking wider boards and ripping out 4" wide boards to laminate into my workbench top, but the knot patterns I had been seeing made this pretty much impossible for the vast majority of the boards I found. The 2x material here was much better quality than what I saw a couple of weeks ago in the same store.
I also went to Delaware this weekend to pick up a combination jointer-planer from Woodcraft (but that's another story). I stopped into a Home Depot and found that the type of 2x wood they carried was much different. They only had kiln-dried hem-fir 2x material. No Douglas fir at all. This stuff had slightly more knots, but the knots themselves were smaller.
So it looks like that there definitely is regional variation in what is available for 2x material. Also, there is an element of luck as to what the big box retailers have at any one time.
