Tell him you are going to be using it for wall art, and thus it's worth about $25 to you now. As a framebuilder, I have to confess I would never take this job. However, if I had made this mistake I wouldn't charge for it.

Dick was the engineer at Trek when they first started. His wife also built frames at Trek. He was meticulous when he built frames, which didn't happen very often when I was there. I wish I knew what happened to him.
