EDM appears very much like magic. It's sometimes the best solution, just not cheap and seldom 'handy'. http://www.wiretechedm.com/ For a broken flush hardened 3mm screw in a chromed part EDM makes sense. For an exhaust flange bolt it's probably overkill. -- Andrew Muzi <www.yellowjersey.org/> Open every day since 1 April, 1971 |

What good is a lubricant that doesn't last very long? Especially when it leaves sticky varnish behind when it evaporates? --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
