On my last raising the crane operator had mistakenly put his hands on the wrong levers and lifted the truss we had just set and pegged. He lifted the truss, top plates and post 4". All this was hanging on two pegs, one on each side of the english tying joint truss. 3/4" pegs, 4" tenons, when I knocked out the stressed peg to view the damage I noticed the peg had the tenon shape impressed into it and it was cracked. Any draw bored peg will have a similar impression, hopefully with out the crack. I believe one more way to tell if a joint was draw bored is to look for the tenon impression. Tim
