I have a peculiar issue:
I've been cutting boards lately on my TS, the Bosch Contractor saw. Strips between 1-6" of all types of woods, and then I'm gluing them together. They all fit together great making nice seams. All, that is, except for one. I've got one board of Ash that will NOT give me a straight edge. I could mix up all the other dozen strips, drop them like "pick-up sticks" but them together in any order and they all fit together great except for this one side of ash (the board has walnut glued to the other edge that's straight).
I've cut it on the table saw with the wide side against the fence, the narrow side against the fence, and I've cut it on a sled--you know, the kind you use for making skew cuts. Several times I might add. As soon as I lay the freshly cut side against any other side of any board, the freshly cut one is not straight. It's bowed in the middle and will NOT make a nice seam.
Has anyone ever heard of this? Is it possible there's some kind of internal stress in the board that will prevent it from giving me a straight side?
