I would do as the first two suggest but also use some epoxy too
I had a customer insist on having a braze-on mount on his 753 frame. I told him Reynolds did not recommend this, but he was insistent. So it went on. A few month later the frame came back: he had jammed his chain in the front derailleur and the mount tore the seat tube open like a can opener. That was the end of that frame.
Oh, and +1 on the epoxy, as long as it is compatible with the CF tubing.
