Now forget all you think you know about this and listen. Pretend for a moment you have no idea what a torque wrench is and have never seen one. The .8 multiplier is a constant that applies to our prop wrench and does not change. Our 3" tool is simply a
torque multiplier period, nothing else. If you use this tool on your bolts, it and it alone boosts the power of what ever devise you use to tighten the bolts by a factor of
plus 20%. That requires you to set your tool, be it your weight lifter mother in-law or a heavy rock on a rope to
EXACTLY 80% of the desired value.
THIS IS A FACT AND WILL NOT CHANGE under any circumstances. This is 7th grade math, not rocket science. If you are looking for 70ft.lb. on your bolts 70 X .8= 56ft.lb. setting on what ever you use to pull with.
... Now I need to search out a formula to re-calculate the 3.1416 number in pie as it will no longer hold true because I am using a longer pencil to do the math.
