Title: Impossible to have perfect flight?
Post by: Robert Honaker on February 04, 2010, 07:22:00 PM
Is it possible that a bow may have a week limb or improper tiller so that it will never have perfect flight?

No matter where my nock point is set I get a severe 'kick" on the tail end of shaft. From 1/4  to 7/8 nock point.. Left/right is good. Bare shafted and and same result... hits about a foot low and if I lower NP it gets even worse.

What yall think?

I'd be hard-pressed to hit anything
with a 1/4" to 7/8" brace height.

Tell us more, don't be shy with the type font   :D

I had a bow like that but it was a bow made by a local bowyer and I think the tiller was messed up or something.

I like to use two nocks over and under the it seems to help for me. You still need the right arrow and tuning though .

Are you shooting three under if so the arrow can be sliding down the string on release I saw this happen first hand Lee at tradtec showed me a  high speed slowmotion film that showed it happening at tradtec one time. There is a thread on here of *********** that talks about that this guy wrapped serving below his arrow to stop it. You could try puting a nock point below arrow just to see if that helps.  Widow

It can be the bow. I made one once when learning, and it would shoot in the dirt until you got used to it. It was way out of tiller. There is more to tillering a bow than a couple measurements. Try weighting one end then the other and see if anything changes.

Here's the problem.  When you have your NP set too low, the arrow hits the shelf and kicks up, making it look too high.  In fact you can't get a BS to shoot nock too low.

Use two nocking points one above and one below.  Start too high and when you move it more it just a 1/16th.

Don't be mistaken, I know how to shoot and tune. I was just wondrin if a bow could be messed up in the tiller dept.
I have never had a bow act like this.

I have shot some aweful bows over the years. I would venture to guess that "yes"  a bow can be unshootable/untuneable.

Try talking to the Boyer who made it and see if he has any suggestions.Better yet,ask him if you can send it back to him to have it checked out.

Can You post pix of the bow?
un-braced
braced
half drawn
full draw

Also when the bow is braced measure at the fades to the string, they should be even or top limb 1/8" longer/higher. post pix and info.

Tried this with one I had doing the same thing one time, he told me to find it a good home.

With your bow arm straight out, pulling slowly
to full draw, does the bow 'want' to drift up or down?

You haven't listed your arrows, etc.  Hard for us to tell or suggest anything without some idea of where you are with arrow spine/length, etc.

Robert try raising your brace height. I had the same problem and an old archer told me to try it. It worked for me.

The term "perfect flight" is way over-used hereabouts.  By definition, it's not possible to attain. And although the pursuit is justified, I believe the end result is over-rated to a point.

I recall one of the top tournament archers of the 80's telling how, after he had won a national title with a couple possibles along the way, shooting the bow/arrow combo through paper and finding the tear proved he was radically out of tune.

The first deer I killed when I got back into trad a number of years back was a complete pass through at 20 yards with a bow/arrow combo that later shooting through paper proved to be also radically out of tune, due to my minimal knowledge of recurve set up at the time.

Now that I got that off my chest...  no question tiller can be off, but you can't attain a tune with an arrow in the proper spine range because of it?  I'm less sure on that point.  I suppose with a production bow, it's possible it got through final inspection so out of whack, but if it was built by a bowyer?  Highly unlikely...

At any rate, I think you need to consult the bowyer who made the bow and work from that point of expert advice...

"Is it possible that a bow may have a week limb or improper tiller so that it will never have perfect flight?"

Yes, that's very possible Robert. Speaking here only from a selfbow maker's perspective though. Limbs twisting as you draw your bow will cause that. Best way I know to combat that is with a very light grip.........ART

Sent you a PM.

Thanks for the suggestions.
I will try a nock above and below the arrow when the rain stops.
An elevated rest would be an option to try, but I really don't want to do that.

For what it's worth, you might try the elevated rest.  They really help arrow flight.  I have them on all my bows that I can use them on...
