What cause arrows when flying to have a "corkscrew" type flight path??

Thanks Matt

I'll try to be nice. 9 times out of ten straight offset fletching out of a bow that is not tuned.

Spine too soft will cause it also....

Quick spins and a improperly glued vane will do it :confused:

Crazy C - it funny you mention quikspins. I have been shooting 4" quikspins for the last year with no problems. I just switched to the 2.25 to try them out and that is when the "corkscrewing" started.

The arrows I was shooting today had just been fletched the night before and all of them were locked on solid. Any other suggestions?

is it a tight corkscrew or a big one. could be contact, or it could be centershot and nocking pt is off. if its a real tight one its probably contact.

are you sure you're not just seeing it spin? if not probably centershot and/or nock height.

The usual cause: fletches of 2 different colors. :D

Quick-Spins don't have real good weight tolerance. On a recent package of 36, I found a 1.8 grain variation in weight. The corkscrew might be due to having two vanes at the low end of the range and one at the high end of the range or visa versa.

I've never tested to see if this weight difference can cause corkscrewing. They are too expensive. I just try to match up QS vanes so that all of them on each arrow are the very close to the same weight.

Hope this helps

I have helped a few of my friends with thier bows. On at least 3 different occasions I was assured that they were not haveing flecth contact problems. On all three of those and a few more I showed them the fletch contact and when gotten rid off. everything was tuneable and good to go. Yep some were drop aways too.

I used Lipstick to show where the flletchings were hitting the rest.

good luck..

Fletch clearance problems on a dropaway? Heresy! I thought they were designed to eliminate this problem? :D :D

Is it happening to all your arrows, or just one or two that you have noticed this effect on?

Are you shooting indoors or outdoors? If outdoors, which way does the perdominant wind blow when shooting??

Do you have any of your old 4" vaned arrows? Do they cork-screw with them on?

BTW Matt... where do you go shoot, Barefoot Archery?

As crazy as it sounds, one odd color feather can give you this impression.

I had to shoot at dusk with a Luminock to prove it to myself.
