Sorry for being late to the topic, but I just found this thread. I had an exterior door made in an Old English style for a walk-out basement renovation. As mentioned, the door was made with gaps between the planks to allow for expansion/contraction. If you use square doornail studs, they should be installed with the points in a diamond pattern (not square). Here's a shot of the finished door (after a few years in the weather).
