I want to attach two 5'6" red oak boards together as part of a table, both 3" x 0.75" at a 90 degree angle, like this:
I was planning on gluing them and adding some pocket screws on the inside, since it'll be hidden.
I'm not sure if this will cause problems in the long run if the boards expand or contract. I'm also not sure if the pocket screws help at all, or if they're redundant as long as I clamp it enough.
