I have 2 questions, first, when I did a workshop many years ago we drilled the peg holes at the time we assembled the frame on the first floor deck of the house, so we simply had a scrap of 2x4 as a backer for the drilling. How are you able to drill from both sides? what is the orientation of your frame when drilling? Second, could someone please give a description of the process of creation the offset holes for a draw bore, Many thanks!!!
