Hi Will thanks for your reply (Infamous double draw-are you john waynes sidekick? wink ) Personally I love drawbore pinning (I've always used it a lot in regular joinery but I am new to framing) and have never had trouble with it except at first when I tended to ofset too much and sheared out the tongues. eek :rolleyes:
Seriously though by counterintuitive direction is that what you mean by moving your offset towards the shoulder of the tenon? If you want to pull in a certain direction you offset towards the shoulder in that direction. So on the rafter joint you ofset slightly toward the inner corner to get a tight pull in two directions??
Cheers, Jonathan
