HOW TO CALCULATE WEIGHT FORWARD FOR YOUR ARROW
Excerpt from TRADITIONAL BOWHUNTER MAGAZINE, Feb-March 2008 written by David Peterson interviewing Dr. Ed Ashby. FoC is foward-of-center
The AMO Standard percent FoC is determined by measuring the length of the arrow's shaft from bottom of the nock's throat to the back of the broadhead. This is 'shaft length'.
With the broadhead mounted on the shaft, the arrow's balance point is determined by balancing it on a knife's edge. The distance from the bottom of the knock's throat to the balance point is the second measurement.
Divide the distance from the knock throat to balance point by the shaft length. This gives the decimal equivalent of the percentage of overall shaft length at which the blaance point falls. From the quotient, subtract .50, the decimal equvilent of 50%. The resulting decimal fraction is converted to the percent FoC by multipling by 100; or simply moving the decimal point two places to the right. Between 12% and 19% is study defined as by FoC, with 20% and over rated extreme. At 12% or below is normal FoC."
