Not sure if any of you have ever noticed the same thing, as me but this is from my experience.
when the prop tool is in the vice, and you first put the prop in the pump try spinning the pump.
As you start to tighten the prop take note to the resistence and how many revolutions the pump will make.
As you get close to the desired ft/lbs you will notice that there is more resistence and the pump makes fewer revolutions.
I have noticed that if i take the torque up to 100 ft lbs and then just barely back off the torque by just a hair the pump spins much more freely.
Not sure how much this actually helps but I have always done this as it still puts me in the 92-95 ft/lb range but i get more revolutions when turning the pump then if i just torqued it 92 ft/lbs.
I just wanted to see if anyone else has ever noticed the difference in resistence with slightly backing off the torque?
I guess this is what happens when you contstantly pull a prop for fine tunning the pitch.
