And I was so proud of the through dovetails I'd hand cut for a drawer. Yet another reason to use marking system that shows you which part goes where and how it will be oriented. Just might help you avoid the following OOPS!
Here's another one, yet another routed groove screw up. If this groove for the drawer bottom fell in the socket of the pins the tails would have covered it. This should have been a stopped dado. Always check before you start to cut a dado.
