One of the other ways to do the breadboard end would be to make a sandwich instead of using a piece of solid wood on the end. You could make it interesting by using a different colored wood for the core than the top and bottom pieces which would also hide the glue joint. Change the problem into a "design opportunity" as Harry likes to call his work arounds when things don't go as planned.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
