Which feathers did you get and where did you get them?
I don't believe that Ashby ever talked about an A&A fletch in his reports. But he does talk about them in several podcasts. Keep in mind that these arrow lethality studies are an on-going study. The Ashby reports are older and may not entirely reflect his current beliefs on arrow building.
Thanks for posting the link to that excellent video. I've probably watched that a dozen times during the last year.
Appreciate the update. I was actually looking at that jig on tuffhead’s site. I may try the a&a jig from them and fletch some up once I settle on point weight. My jig only does 1 degree offset so I may end up getting another to straight fletchbut I’ll likely try the 1 degree first.
I have not tried the turbulator because I did not stay with the A&A. Not because I didn't try the A&A, I did try them. They worked fine as far as the flight goes, but I just did not like how I made the feathers themselves. I first tried cutting them and I couldn't seem to get a nice clean cut. Then I rigged up a chopper which may have been deforming the quill a little bit because when I put them in my Bitzenburger clamp, they just wouldn't lay straight on the small diameter shaft. I was using tape instead of glue because that's what they recommend for those GrizzlyStik Momomentum shafts...they have a coating on them for increased penetration and also pull out of targets easier, but they say glue doesn't stick as well as tape. So...I just wasn't happy with the end product of my fletch job with the A&A. The leading tip of the quill seemed to curl a little and was not adhered down very well. At that point, I decided to try the Trueflight feathers and they laid much nicer on the shaft so I saw no need for the turbulator with the factory made feathers.
I was convinced that there had to be some level of rotational momentum when the arrow began penetration (with a single bevel head).
I’m leaning more towards the true flight feathers I already have on standby as well as aae trad vanes. Both of which fly the same for what I’m shooting now. I may tinker and try a couple a&a but I doubt I will. As far as the turbulator goes, I most likely won’t attempt bc as you said I really can’t see it making much of a difference. At this point I’m just more concerned with my form and a properly tuned set up and Maybe dig more into the weeds later. I wouldn’t consider myself accurate enough with my recurve for something like that to make a difference and some offset or helical with my fletchings is probably what I need to correct for subtle form flaws. Appreciate the input Tom!
Not true in cases. The arrow I set up this year was very well tuned. Offset Fletched arrows grouped great. I was crashing bareshafts at 20 yds. You could touch your thumb and middle finger around the group field point and bareshafts. 30yd group was pretty dang good as well. As soon as I put a BH on I got IMO less then desirable results.They grouped but not to my standards. Offset fletching just wouldn't spin them enough. helical fletching solved it. I talked to Troy and he said a BH can make an arrow act weak even the thought the field point behaves and goes down the middle.
As soon as the arrow hits any flight rotation stops and the single bevel rotation by cutting begins. It makes sense that flight rotation plays very little into the cutting action.
