I'm in the midst of building 7 bookcases for our new house. I've got the cases together and am starting on the face frames. Usually I do my own design, but I ran across a plan I really liked the looks of so I'm using it.
The face frame has a 2.5" wide top rail and a 5.5" wide bottom rail. The stiles are 2" wide. Not worried about the top rail but that wide bottom rail seems to me to be pushing the limits for cross-grain construction.
A bottom trim piece will cover the lower 3.5" of the bottom rail. I'm considering splitting the rail into 3" and 2" pieces and leaving a 1/2" gap, which will be covered by the trim, between them. But that's a bit of extra work I don't want to do if it isn't needed. Am I being overly paranoid about wood movement?
BTW, between shelf pin holes, holes for connectors, screw holes for levelers, and holes for screws to attach the trim, I drilled almost 1000 holes! I don't want to see a drill bit for the next 6 months :-).
