Sometimes my arrows spin and sometimes they flight without any rotation what so ever. I shoot full lenth GT 55/75's a 250 gr head and a 50 gr brass insert, with 5" parabolic LW fletch. Should they always spin or rotate like a rifle bullet? Thank you
-
Are you fletching them with a left helical clamp?
-
Yes. The fletching looks like it should be spinning the arrows to beat the band but they don't spin more than they do spin. I was wondering if it was due to my heavy point weight. I do should three under if that matters.
-
They should be spinning about as soon as they leave the bow. I shoot 250gr. 3 blades and I get good rotation. Are you sure your eyes aren't playing tricks on you? If they rotate some of the time then they should rotate every time.
-
They might be. It just seems that sometimes the rotation is very easy to see.
-
Were all of the fletchings put on using the same jig? Was the jig not adjusted between doing different arrows? Are all of the feathers from the same batch/bag? If the answers to above questions are all yes the arrows should fly the same. Are they all the same color? If they are a different color maybe they just look like they are not spinning. The only other issue might be that the arrow shafts are mismarked. I use to be a Gold Tip dealer and we went thru a short time when we received some mis-marked shafts, but that was several years ago. Different fitting nocks might be a cause but that is not likely. My guess is that the feathers were installed slightly differently, maybe the clamp was not sitting in the jig correctly. But the most likely cause is the arrow nock was not in correct position on the jig, dead center of the "V" slot. This happens a lot, a common problem especially on multi jigs such as Jojan.
-
Same jig. I do one at a time. It is an old BPE jig. The nock placement sounds like it could be operator error. I have been going to buy a Bitzenberger. The jig I have has had some use but all the fletchings seem to look the same arrow to arrow.
-
Physics isn't variable. If they spin once, they spin. Actually, if you are watching your arrows spin, you are probably missing your target. When I am "on" I am staring at my "spot" all the way through the shot. The arrow kind of enters my vision at the last instant. Sometimes I notice a bit of rotation, mostly I don't.
The good news for you is you probably have your form and shot sequence down to the point that you are focused on the spot and not really noticing the spin. Even when you think you want to watch the flight, your subconscious takes over on the shot and won't let you...not a bad thing at all.
-
I only seem to notice it on the longer shots, the shots I practice but would never take at an animal. I will have to pay closer attention to my spot and forget about overthinking this. I am trying not to be a tweaker. Thank you
-
I think what is happening is on those just right releases when the arrow is flying perfect you are looking right down the back of the arrow and see the spin as the arrow leaves the bow, but with a release or a form issue that is just a little off the arrow will not have that perfect flight (still good flight)and you are then not looking right down the back of the arrow and therefore cant see the spin.
-
I think you might be right. When I do seee it spin it is a perfect shot ( I don't get many of those) absolutely perfect.
-
It happens sometimes. Most times my arrows spin into a blur all the way in. Once in a while it looks like a knuckleball pitch where you can watch the individual feathers making maybe one rotation in 20yd. Next time I shoot that arrow it spins just fine.
And yes, I know how to fletch, use the same jig, same feathers, know how to shoot, etc, etc. Maybe there was a brief tail wind or something?????
I've seen it with field points as well as broadheads. They all fly great so I'm not too concerned with an occasional slow-spinner.
-
That's it. I was concerned that I got caught up in the extreme FOC deal and when I got the front end of the arrow moving it was just dragging the rear behind it. This is, of course, carpenter logic, not from anyone with any real mathematical ability.
