... and then I notced the mistake.

Here's some pics of the dovetails. Each side... if you look closely at the pics of the dovetails you'll see the problem. Just in case you didn't notice, I put an annotated pic up. Seems that somewhere between cutting the dovetails on the first side and starting the second I lost track of which side was which. Oh well. At least you can't tell from looking at the front.
