OK, that sounds good, I will look into the draw bore method more closely. My foundation is mono slab and is easily reconciled to level and square. I was struck by Bensons statement from his BTTFH book that he felt the drawing of the bent together on the deck with straps and come alongs was "superior to draw boring" Having never assembled a frame it just seemed that one could assemble and kerf for fit and square then cinch it up with straps and drill and peg, Viola! I envision draw boring as doing the above and then pulling each joint apart to drill a second time through the tennon and reassembling again. Never been there done that but would like to hear opinions on the other side of the aisle besides Benson. Gracis Bman
