Title: Why cock fletch in
Post by: Jim Brennen on September 02, 2013, 05:50:00 PM
Hello, I just made a new set of douglas fir woodies,3 shield cut turkey feathers 5 inch. With a field point they fly good,I Put a zwickey delta on and if I shoot cock fletch in they fly great,cock fletch out they don't. I shoot this spine arrow without broadheads and they fly great. Is this a tuning problem?

I seem to get better flight with cock feather in too.  Might be a tuning issue, but maybe not.  That with the Toelke?  All I've had seem to like them that way, most other bows don't seem to care. I just shoot it in on all of them and don't worry about it.

You may be very close to having to  weak a shaft. A broadhead will usually slightly weaken spine in some cases. In most cases it's not enough to matter unless you are very close to having a weak spine for your setup. What length, weight broadhead and spine arrow are you shooting?

Maybe just in my head, but I feel my Toelke shoots better cock feather in also.

Hen feather drags cock feather out. Cock feather in puts the hen feather further from the bow during paradox.

Hello, Its my shrew bow in question. I'm shooting 55/60 spine at 28 inches bop with 135 grain broadhead. I only draw 26 inches so my bow is around 45 at my draw. They may be border line weak, I may just have to shoot with cock feather in. Thanks

I have a bow like that.  Bareshafts are right on, so it isn't a spine issue.  I just roll with it.

When you shoot cock feather in you can also drop your nock point between a 1/8" - 1/4".  Rotating it allows the hen to not strike dead center on your shelf during the release.  Changed when I read that tip on "arrow by Kelly" website.

I guess it's the bow that likes cock feather in with just the broadheads since the field points shoot true with cock feather out and vice versa. Or as Buckeye said adjust knocking point. My bad.

I'd say the cock feather is on the stiff side of the arrow. The actual feather placement doesn't have a different affect on the arrow flight but the stiff side of a wood arrow does.

A couple guys mentioned that the bow might just like the arrow positioned one way or another....are yall saying that the fletching isn't clearing properly?   How does a bow "like" a feather in or out?  Not being a smartalec, just that I'm not following what you're saying.
Title: Re: Why cock fletch in
Post by: cahaba on September 03, 2013, 02:04:00 AM
I had a setup one time  that shot field points great but wouldn't shoot my broadheads right. I went up to a different spine and it cured the problem. That is why I felt he may have an arrow that is slightly weak at least on the cock feather out side.

During paradox, the arrow bends away from riser but with cock feather out, the lower hen feather will likely hit the edge of the shelf if the shelf is wide. With cock feather in, the hen points away from shelf reducing contact.

If the quill of the hen feather hits the shelf, it will affect arrow flight.  Turn the arrow around to cock-feather in and you move the offending hen out of the way.

Could it be that it may be more pronounced with a short brace height?  The arrow (hen feather) never gets time to rotate away from the shelf or does the arrow not start to spin that quickly off the string.

Kelly Peterson (in business for many years as Arrows by Kelly) had an explanation of why shooting cock feather in is good.

I wish I could find it but after Kelly retired from arrowsmithing his great website disappeared.

Whatever his reason was I tried cock feather in and it worked well and I've not looked back.

Cock feather in not so good for double anchor of feather on nose.  So if you shoot in what do you use as a double anchor?

Thumb joint behind jaw bone, finger on first molar.  A double anchor isn't actually required anyway, just what some people choose to do.

Sent you a PM with photos the other day. I will repost pics here. If your RH, shooting RW feathers, the odd hen is down when nocked normally. Turn cock feather in, odd hen is "UP". Put LW feathers on, nock normal with cock feather out and odd hen is "UP".

I shot cock feather in for years now all my arrows are fletched LW when shooting my RH bows and right wing when shooting my left handed Fedora.

RW fletched cock feather normal. RH Shooter

Was able to salvage my old website so that the info contained on it can still be available to everyone. No am not going back into the business.

Actually Joe Skipp explained it pretty good with the above pictures.

I have found all my recurves have shot better cock feather in. Never really worried about why, just as long as the arrow flew well...

May not be necessary for some but it is for me, just curious as to what you used if the cock feather was in.

Post by: BuckeyeGuy on September 03, 2013, 03:41:00 PM
Widow, with cock feather in you can't use it for sure. I used to use that as one anchor when I shot out.  I'm index finger corner of mouth and thumb joint behind jaw bone fyi.

The Reasoning for Cock feather in is very simple! It has nothing to do with Arrow spine, feather contact etc> It is easily explained by looking at the top 2 Pics that Joe skipp posted , Cock feather out the cock feather slices thru the air, Cock feather in the 2 hen feathers facing out act as a parachute effect during the archers paradox. THAT'S IT !!  :deadhorse:

Thank You everybody for all the responses and Joe Skipp those pictures explain it great. I'm just going to shoot cock fletch in.

I shoot a lot of cock feather in.  When in hen feathers catch more air and correct faster.

Post by: akbowbender on September 03, 2013, 10:27:00 PM
It depends on the bow for me: my NM Classic-cock out, my JD Berry Misty Dawn and Dave Johnson-cock in. Can mess me up a bit when I'm switching between bows.

I shoot off the shelf and cock feather in for all the reasons already given.Works for me.

I have never been able to paper tune my toelke whip. No matter where I moved my nock I always got a 2 inch nock high tear. Today I paper tuned with cock feather in and got perfect tears after 5 minutes of tuning.  Broadheads flying great as well. I wish I would have tried this months ago. Thanks for posting this thread

Likely arrows are too stiff by just a tad. Flying great with broadhead (broadheads usually like a stiffer arrow) but not with field pt.

stiff arrows don't paradox as much as weak ones thus not allowing the feathers to clear the shelf.

by turning cock feather in makes clearance for hen feathers that haven't paradoxed enough.

It's amazing to me how guys can spend hundreds of hours tuning and never try cock feather in.  I've picked up used bows before with the nock point set an inch over square and I can only assume the poor guy was trying to tune out a nock high issue.  If he had just flipped that arrow over, he might have fixed his problem.  It has certainly worked that.way for me.
Title: Re: Why cock fletch in
Post by: LC on September 05, 2013, 10:13:00 PM
OK here is my take on this. Your mileage may vary. I ALWAYS shoot cock feather in. To be honest it's  not about getting a arrow to shoot right but more for  about getting a clean feather clearance upon release. I bare shaft tune my arrows so they fly like laser beams without fletching.

Here is the way it was explained to me and always worked and made sense. Nock a arrow on your bow string at brace height. NOW imagine upon release where the arrow finally comes loose from the string. To help you it's not where you see it nocked at brace height. The string follows the arrow past brace height. A arrow can't begin to spin while still controlled by the string! PERIOD.  Now with arrow on the string at brace height push it towards the belly like it happens in real life after shooting a arrow!

The arrow CAN NOT begin to spin till after it's released from the string! PERIOD! Just repeating a important fact.

With that said years ago, showing my age, all tuning manuals use to show  leaving a gap between the arrow shelf and the riser back. Supposedly to let the lower hen feather go between this "GAP"!

Problem is when you watch a slow motion video of a properly spined arrow the tail end of the arrow shaft is riding almost off the arrow shelf!

So regardless if shooting right or left with the cock feather out the bottom hen feather is making contact with the bows shelf ON THE OUTSIDE AREA.  Turning the cock feather in helps to reduce this but turning it in at the RIGHT angle elimates all feather contact. JMHO!

In a nut shell I don't do it to compensate for  a poorly spined arrow but simply for better fletching clearance.

Read this thread today and tried it out this evening. Wow, I can definitely say my Striker LB prefers cock feather in, to the tune of shrinking groups in half. Can't wait to try it on my recurves. Just gotta love TradGang for little Pearls like this thread!
