I won't speak for Jerry, but I'm sure he'd agree with me on this response. Keep in mind that today certain arrow shaft manufacturers and arrow builders use longer than standard inserts on their shaft to stiffen or another words change the static and dynamic properties of that shaft. These longer inserts can be anywhere from as little as 1/2" longer to almost 3" longer than a standard insert. It just depends on how much stiffer an arrow they are trying to produce.Question for Jon Henry or Jerry I bought my Ram and Analyser back in 2012 and I kept all info you guys posted over the years but when watching the video one thing came to my head and I could not find the article I had so I need to pick your brain It stated that a shaft should be cut before spine testing , cutting a shaft as little as one and a half inches can change the index mark up to 3.5 degrees any feed back would be appreciated thanks John
The same can said when we shorted the length of an arrow shaft by cutting it. The fact is that it produces a somewhat stiffer shaft. The manufacturer of the RAM QC Arrow Shaft Spine Tester is providing instructions which permit you to achieve the most accurate testing results that you can achieve. As Jerry has already stated numerous times in the past, today we have carbon arrow shafts that are made from a number of different methods. Sometimes the carbon fiber material is wrapped in such a way as to curve or spiral the seam around the shaft. Sometimes a number of the very top carbon shafts are produced by bonding a shaft within a shaft. there are probably numerous other new ways of running the carbon materials that I'm not up on.
My point is that if as an example you were working with a set of carbon shafts who's fibers wrap or spiral around the inside of the shaft and you don't cut the shaft to proper length ahead of time, then very likely when you do cut it the "Stiff Side Plain" may have moved slight once you cut that shaft to a shorter length.
From my point of view these issues can easily be eliminated by following the arrow building process in the correct sequence which would remove any of these possible problems.
Jerry's statement above is very understandable. The technology that surrounds the properties of arrow performance along with the How-To's is not a deep science. While there are some things to learn and understand, for those who've been working with it for a number of years and have a reasonable understanding, they neither care who writes about it or what they may think. The reason is very simple. Nobody can change the laws of physics and the process of arrow building rarely ever changes.
I've been building my own arrows for over 50 years, however Jerry builds more arrows in one week than most people will ever build in an entire lifetime. Experience counts for a great deal in this arena.
I hope this explanation helps!
