As others have said, it might have whipped during turning. You might even have had a lucky escape. If it had bent through whipping then you should be able to find out where the bend it (probably just behind where the chuck jaws held it) and by holding it the other way round at the same point you might well be able to bend it straight again. My feeling would be that there won't be any significant loss of pitch accuracy doing this. You may have different definitions of "significant" -- atp ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
