Can this dropout be salvaged?
This is a late 90s Canadian made Peugeot. I was in the midst of a teardown to prep the frame for a rebuild when I discovered a broken right dropout.


Not sure the frame is worth putting new dropouts in, but if this break is repairable, I would be willing to give it a shot. What are my chances?

The quick fix would be to grind out the crack into a nice clean "V" profile trench and TIG weld it together. If done skillfully, it would be hardly noticeable under paint.
Otherwise, dropouts can be replaced. No guarantees on ease of finding one that matches the other side, if that's important to you.

Your dropout appears to be a forged dropout, possibly a SunTour GT:

Cast dropouts usually have external sockets for the stays rather than a tab that inserts into a slot in the stay. I've never tried welding a cast dropout, but I suppose success would depend on the material.

Thanks for the input everyone. I'll cart it off to a welding shop to see if I can get 'er done. I don't think it's a job for my little hobby stick welder and my very limited skills with it.

I found a local welder to fix me up.
Let the build begin.

So, all good. Build complete and ready for delivery. Thanks to all for the input.

However, I'd imagine the new dropouts one can buy are cast steel, or cast stainless steel, and should be weldable. I would think that many are designed to be either welded or brazed for assembly.
Aluminum might be different. Vintage cast aluminum could be an issue. New cast (or extruded) aluminum would all be intended to be welded.
....
Glad the weld and the project turned out well.
