In case anyone still wonders how to do this..
When I did mine, I went back to basic physics:
Torque = Force (in lb) X Distance (in feet)
Rearrange the equation and pop in the numbers you know (specified torque and your weight). I weigh about 195 lb, so for me:
Distance = Torque/Force=340 ft-lb/195 lb
=1.74 ft, or about 21 inches
So I used a breaker bar and used my entire weight applied about 21" out from the nut to tighten it. When using this technique, try to do the final tightening with the breaker bar parallel to the ground, and apply your weight in a straight downward direction.
