This is done by drilling a small hole at the extreme ends of the crack with a drill bit slightly larger than the crack. Stop drilling spreads the stress evenly thus stopping the crack from propagating further. Not sure what damage looks like and would need to see a picture to be able to give further repair advice. Hope this info helps and good luck. Parley Byington N54PB Kr-2 Henderson Nevada byington1954 at embarqmail.com
