Has anyone successfully uncracked a frame?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

We see it all the time, steel cracked, Ti cracked, alu cracked, carbon cracked... they all actually crack sooner or later.

But has anyone actually managed to repair any of their cracked frames no matter material??
How did it turn out? How much did it cost you? Did the repair last?

I have an old Trek that cracked across the seatstay cap lettering on both sides. A local framebuilder repaired them; I believe by heating and lifting off the caps, then adding a lot of braze to the stay end and replacing the caps. The offending letter got filled in on the worst crack.

He also repaired the cracks in the tubes of an even older Raleigh Competition that apparently went straight from jigging and tack-brazing to paint. Didn't ask him the details of how he did the repairs. (He did say that the paint job was excellent; that the painter did a really good job of flowing the paint under the lugs and that the paint was probably holding the bike together!)

Broke a Peugeot UO-8 chainstay years ago behind the bridge. I was a boatbuilder at the time and had a local rigger weld it up.

I doubt the Peugeot repair would have lasted forever. I'll never know. The bike died a violent death two years later. I full expect the other repairs to outlive me.

I’ve done dozens of CF frame repairs. Some are easy, but others are challenging.

Built a wormhole and went back to a time when the bike wasn't cracked. Lasted until it cracked again.

Wormhole? Bah - I dial it up to 1.21 gigawatts and give the space-time continuum "the look."
