To finish this description.  The fulcrum point gives the center of 
gravity.  You then divide the total rod weight by the fraction distance 
from crankpin (center) to center of gravity and wrist pin (center) to 
center of gravity. 

You can also do a direct measurement. Lay a thin rod (I use a finishing 
nail) on your scale.  Rest the small end on a block next to the scale 
and the big end so that the nail is lined up with the center of the 
crankpin.  This way you know you are measuring the weight at the center 
of the crankpin.  Reverse the ends and measure the small end weight. If 
you do it right, the two weights should add up to the total rod weight.

Both of these methods should give similar results.
