I depend of my wood movement calcutor for most cross grain movement. As many say, "longitudinal movement, along the grain, is negligible". What exactly does "negligible" mean? My calculator does not show it, of course.
I am building several 9 to 14" wide by 15" tall cherry panels that will go into a frame. This is for a blanket chest so no doors will be slamming or anything like that. I am out of space balls, and find the idea of nailing in panels a little inelegant. Is that a word?
I have with smaller panels simply put a spot of glue at the top and bottom center of the panels. My concern is that 15" (vertically, with the grain) might expand/contract enough break the top or bottom glue bond. I know yellow glue has some creep and therefore maybe a little give. Am I asking for trouble doing this?
