Product Details

Woodywieghts

Woodyweights were developed by a lifelong traditional bow hunter looking for a better way to add weight to his wood arrows.  Woodyweights not only adds weight to his wood arrows,  by adding weight to the front of the shaft achieveing the advantages of a weight forward arrow.  Weight forward arrows straighten quicker in flight, fly more stable and give better pentration than standard arrows.

Woodyweights are available in six grain weights from 75 to 200 grain, sized to fit 11/32nds and 23/64ths shafts.  Woodyweights have also been used on aluminum and carbon arrows with an adapter and produce excellent results.

This system allows the wood arrow bow-hunter the ability to increase the weight of his/her arrows and adjusts the amount of weight forward.  Hunting arrows can be tuned and dialed into his/her hunting arrows in a way not possible for wood arrows in the past.

How To Apply Woodyweights

Before application of a woodyweight to your shaft; make sure all oily residue from production is removed. This can be done with a cleaning solvent or using heat. If heat is used allow weight to cool before proceeding.

Using a hot melt product such as Ferr-L-Tite, apply the woodyweight to the tapered shaft tip. With smaller arrow shafts make sure the arrow tip is not bottoming out in the weight, if it is remove and clip the point. Rough up the outer surface and then hot melt on any fieldpoint or broadhead.

For aluminum and carbon shafts add an adapter before application. Steel adaptors are  recommended.

                           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."
