    repairing chainsucked stay on Kona CIndercone

    Hello all,
    I'm seeking procedural advice on best way to repair a thinned area on a steel chainstay. This is on a '91 kona Cindercone. Notice the area is slightly concave so I am sure it is very thin in this zone. It's been suggested to silver braze a steel patch over the area? But I'm concerned about maintaining intimate contact under the patch? I have high level welding and brazing skills but would love to hear how a pro would approach this.
    Thanks,
    Glen G

    It's probably concave from crimping for chain ring clearance. Clean up the rust and prime and paint it.

    I would just keep riding it. It's almost 30 years old, it's not worth the effort of cleanup/repair at this point.

    But if you insist on doing it, I'd probably just replace the whole chainstay.

    I considered that but it seemed it was not concave until I pushed on it with an Allen key.
    I know itís not extremely rare or of high value but I have the itch to make it pretty and rideable again. So if it needs fixed I donít want to just paint over it.
    Thanks all.

    Walt, itís just a 91 frame set now. I canít imagine finding a chainstay for it?
    I have a nearly perfect Ď96 CCone but the frame is too small for me. I plan to use the wheels and most of itís groupset to finish it off. Itís my first restoration project. ďEffortĒ whatís that :-)

    There are lots of chainstays in the world. Go look around. If you don't find a nice match, so what? It'll ride fine. If it really bothers you, replace both stays.
