I have been intrigued by EFOC arrows. I like shooting and making wooden arrows rather than the modern faux
arrow material. It has been hard to get high FOC arrows with wood. Along comes Woody Weights and that worked pretty good. My first experiments with Woody Weights proved to me that I had to go up in spine with the addition of the weight up front.I normally shoot 55-60lb. spined arrow with a 145gr. point, but with the addition of a 125gr. Woody Weight I had to go up to 65-70lb. spine shafts. I just didn't like having 2 connections (point to Woody Weight and Woody Weight to shaft) on the front of my arrow. Somewhere I read about drilling a hole in the end of the shaft and filling it whith something heavy. I got a 3/16" steel rod and cut a piece 2 1/4" long and it weighed 123gr. I drilled a 3/16" (actually .004 larger to allow excess glue to excape) hole 2 1/4" deep in the end of a shaft.
and epoxied in the steel rod.
Then I did a second shaft.
I then finished the shafts and put the point taper on. I used a sanding disc on my table saw with a jig I made. I lost a little weight from the steel rod while doing the taper.
The finished tapered larch arrows weigh 715gr. They have a FOC of 18.4%, 1% less than with the Woody Weights. To me these are more esthetically pleasing.
It will be interesting to see how well this system holds up to my rugged abuse. Time will tell.
