Thanks Wayne and thanks for all your advice on how to split the logs all the way to how to use my Veritas dowel maker, it is much appreciated!
I have today finished my second white ash arrow with the twin fledge design, but this time instead of the obsidian point I have added a 125 grain 5/16" field point. As soon as I had it finished, I took it out to the barn and shot the twin fledge arrow and compared its flight and noise to my 3 fledge standard arrow. The result was very encouraging!
The twin fledged arrow was
noticeably quieter than the 3 fledge arrow and I am suspecting that having the tip of the turkey tail feather intact and allowing it to move for the last 1.5 inches might have the effect of shedding vortices and dampening the noise. I had to turn my hay round bale to the side since I had to dig out my 2 fledge arrow out of the bale because it buried itself all the way to the nock. My 3 fledge design did not penetrate as far. Shooting at the round bale from the side with the netting the twin fledge white ash arrow still penetrated the bale approximately 4" deeper than the 3 fledged arrow. This could be partially also due to the smaller diameter of the arrow but it definitely was hitting harder than my other arrow.
My 3 fledge arrow I compared the twin fledge to is ~ 1.25 inch longer (29.25" throat of nock to tip), is 11/32 Douglas Fir with a spine of 52# and weighing 509 grain with a 125 grain field point
The new twin fledge arrow is 28" throat of nock to tip, 5/16" with a spine of 51# and weighing in at 571 grain (125 grain field point)
I am definitely happy with this white ash two fledge turkey tail feather design. Everything on it except for the paint, the sinew and field tip is "homegrown" out of my bush. In addition I am now able to get substantially more fledging out of the turkeys my son and his friends shoot in my bush, I call that a win win
