Although a rotary drill is faster (though still 19th century technology) a cable drill is something that anyone able to keep any sort of machinery running could maintain: it's just a heavy weight on a cable, lifted up and dropped over and over. I suspect that a more serious barrier is the cost of the steel casing. -- John Hasler -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
