Damaged fletching

[cestria]

Hi All,

Shot my new ACC's at the club yesterday and got a PB, chuffed to bits.

I noticed however that one of the fletching on each of the 6 arrows I shot were damaged. I hadn't noticed any particular problem with how the arrows shot, as I was concentrating on getting my sight dialed in.

I am a left hander so please bear this in mind if you have any ideas.

The arrows are fletched straight with small plastifletches and the damaged one is the uppermost hen fletch. I have sussed out that the arrow must be rotating and making contact with the butoon, as there is a small mark on it.

The question is which way is it likley to be rotating and which way to index the nock and by how much to help prevent this from happening? or as with most things in life is it a bit trial and error.

Regards

Dont know if this will help.....I once had a similar problem when shooting longer distances....found that the uppermost fletching was hitting the sight .....I soon changed to an Arten Olympic....no problems now

I'm left handed too. The direction of rotation is left or counter clockwise, if you offset your vanes with the rear of the fletch to the right of the arrow and the front of the fletch to the left of the arrow, looking from above with the arrow facing away from you. if you wish to index the nock, turn it aniclockwise a little and try again.

However, archers paradox "should" leave the back end of the arrow well clear of the rest by the time it passes that point. If there is contact from said hen fletch things need to be looked at in more detail. Probably a spine problem.

You do not say how far you are shooting? if it's a long way, your sight may be well down near the arrow as it passes, I'v had contact on the sight pin at long distance and could explain the marks on the fletch.

Let us know how you get on..

Exact same thing used to happen to me. What spine are your acc's?
And you bow tiller () should be about 1/8th of an inch 3-4mm closer than the top limb on the bottum limb.

I was guided towards 3L-18s for my draw weight which was measured at the shop. I've been shooting Short National 50/40. I'm sure that the problem is the button not the sight as the pin is well out of the way and there is a orangey mark on the button which is the colour of the fletch. Will check things out with the shop on Wednesday when they open again, but was asking for other answers as well.

What is the weight on your fingers and what is you actual arrow length?

[cestria]

The arrows were cut to 29"+ pile and weight was measured @37lb by bow scales

Well it's not the arrows then, they should be spot on at that length.

It's not likely to be a question of arrow rotation - they don't do much of that until they're clear of the bow....
Which bit of the fletch is damaged?

One thing that could be an issue, is clearance, and nocking point. I have had a situation in the past where the rear end of the shaft was dropping far enough to contact the rest as the fletchings passed it. Cured by fiddling with the NP height...

Hi Rik,

As I said in an earlier post, it is the upper hen vane which is damaged. The damage could be described as a ripple, there is was one with a little nick (I assumed on Sunday that this one was clipped by a fellow archer's arrow, now I'm not so sure). If as you say the nocking point maybe wrong, could it be so low to drop the arrow enough to catch the button as the arrow should still be on the rest as it is passing it? My rest by the way is a Spigarelli magnetic.
