Hey Diablo,I don't really want to get into it that far,you pretty much went over my head with that last comment !!! All I know is that if I do it wrong it will end up breaking, it's that simple.
I guess if we follow the criteria set before us from the manufacturers as far as torque specs go,we should be just fine.
I have broken all 6 bolts before on one engine and 3 on another,that was the whole reasoning behind me purchasing a torque wrench just for prop tightening.The reasons behind the failures are pretty much my own fault for not properly tightening them with a good wrench,my advice to all is to invest in one and use it !! RELIGIOUSLY !!!!!!!!!!!!!!!!
