Hey JamesKerr
Hope thing are well in your camp tonight! I have read your post several times, and feel like this is a problem that can be easily solved, with a little logic, and a few fundamentals principles. Let’s break thing down piece by piece, or sentence by sentence.
Your first sentence was: Okay guys I have always used O.L. Adcock's method of bareshaft planing to do my tuning.
Question: What has happened? Why doesn't this method no longer work for you?
From what I have always read the angle the bareshaft flies or sticks in the target is irrelevant as long as it groups in the same area as your fletched arrows.
My opinion: The angle of the shaft doesn't matter after it hits the target, but does matter after the arrow is released, and is in flight: Remember those fundamentals I mentioned in the first paragraph? For a right hand shooter when that arrow is released, if the nock flies to the right that means a stiff shaft, if the nock flies to the left it means a weak shaft. This is not my opinion, this is fact, it’s a fundamental principal, like stepping off a cliff, you fall down, you go dead.
This has worked fine for me for most of my bows and arrow combo's.
Question: Explain what has changed.
I recently saw some video footage though of Ken Beck and Toby Essick shooting bare shafts along with their fletched arrows and not only did their bareshafts group with the fletched arrows but they flew just about as straight as a lot of people would like to get from fletched arrows.
Question: Have you consulted Ken and Toby for advice about your problem? If so, what advice did they offer?
My question is I can not for the life of me seem to get a bare shaft to fly straight. No matter what spine arrow, point weight, or length, they always hit nock right. (I am a right handed shooter).
Advice: Referrer back to your first comment! Explain what has changed!
Did you get a new bow?
New Shafts?
I have shot arrows that should be 10#-15# underspined up to the same amount overspined.
Question: What type of shafts are you shooting?
Carbon, aluminum, wood?
I don't think it is my form because I have good alignment when I compare myself to Terry's Clock picture and I almost always get a clean release with my string hand ending up back by my ear.
Comment: You don’t THINK?
When tuning bare shaft, you must know that you know that you know you are getting a clean release. If in doubt, practice, practice, practice. Try and post some video on the shooting forum, and get Mobow, and McDave involved.
I would just like to know what these guys are apparently doing differently than I am.
Comment: No offence, but from this comment it sounds like to me, that you are lacking a few fundamental skill, that could easily solve this problem.
Advice: You need to study the archers paradox, reread O.L. Adcock's method of bareshaft planning. I too learn this method from O.L. Adcock and found it very helpful once I understood the archers paradox.
Good luck, and this is just my opinion, I could be wrong!
