ok. at this point with the tail of the plug in the pin, I slide the whole thing, plug an the right side of the lathe into the longer bit very slowly, only about a 1/2" at a time an then backing off to clear the bit. then push the plug on again,,,back an forth,,, till I'm atleast alittle more than half way threw the plug...then turn the plug around an repeat , you can feel the bit hit the other side of the hole that you have just drilled...take the plug off an get it alittle blow [in the hole] to clear out the dust...this only takes sec.'s when you get going an I've never had a miss.
