I've been looking at making some horizontal slat doors (not louvered) for cabinets, and wondering how to prevent expansion and contraction problems. If you have a 40" tall cope and stick door, and glue up a solid horizontal grain panel, you're going to have some terrific expansion problems. I wouldn't be surprised if the panel didn't pop off the top and bottom rails at the first weather change... Even if you coped and ship lapped 2-1/2" wide by 1/2" thick slats and stacked them in the door frame, you'll still have expansion problems...
I'm wondering how to overcome that..
Any ideas on the best way to construct such a door?
