Easton tuning guide

[hoyt21]

It could but you could have your rest cocked left or right to get them to impact which is not ideal

One other thing. The Easton tuning guide mentiones the effect of cam alignment and lean and how the rest is moved on a compound bow to compensate for the effects of it. Is your beef the fact that you would rather them go into depth on how to correct cam clean for bows whose lean can be addressed?

The guide is pretty clear, it states that the arrow is behaving like it is stiff or weak (doesn't actually say it is either... just behaves like it.) All of this is in step 14. In section 8 it discusses how on a compound bow the rest is moved to compensate, in part for cam alignment influences on string travel compared to the centerline of the bow.

Okay, so I'd say that has more to do with tuning the bow itself. The bow should have already ben setup to ensure the least amount of horizontal nock travel as possible. From there, if the design does not allow for it to be compeltely removed, then rest movement is necessary.

I don't see where the Easton tuning guide goes against that philosophy. You just have to read the whole thing.

I think those same assumptions are made buy the easton tuning guide as well.



I am following this. This is what I was assuming the impact was.

So what we are dealing with is the concept that something, anything, can cause the arrow to kick during launch. The fletching and broadheads have a steering affect that either stabilize/exasterbate the arrows ability to recover, and fly straight.

the position of the rest to the certerline of the string travel can induce this kick. So too can a centered rest, but a horizontal moving nocking point. Torquing during the shot is an issue as well.

I'm still a little confused:

Would moving the rest in the above scenario still not allieviate the flight issue? I would argue, if you have horizontal nock travel, aren't you not seeing issues because of recovery in the horizontal plane movement? Wouldn't spine have an impact on that?

Remember, depending on the lean and the direction of the lean, it could be that the arrow is moving in such a direction to be a "left handed" shooter impact. Meaning, what it was showing was really a stiff arrow with left to right nock end movement. I'm curious... in the case above. What the nock movement, due to cam lean left to right, or was it right to left?

Yes and no on the spine. If an arrow is weak. But with in reason. The side tear or horizontal tear is the miss alinement of rest to the power stroke. Center shot.
Not a weak or stiff arrow.

A very weak arrow will normally give you a high tear. Depending on how close you are to the paper.

You have to remember. A arrow being shot with a release flexes up/dn not side to side. Meaning if you have a up tear and you do all the fixes and it's still not fixed then you need to look at spine of arrow.

Its hard to see a weak arrow till you try to group shoot a fixed broadheads.

Yes it is tuning the bow. where the Easton tuning goes against its philosophy is saying this is a weak arrow reaction. Then telling you to move the rest.

If this was truly a weak reaction then it would say put a lighter tip, heavier knoc or lower poundage. Moving rest would never be mentioned

T would be better to say if you have a left tear or right tear is a indicator that the arrow is not in line with the power stroke. Move rest or yoke tune bow.

If arrow is truly weak. Moving the rest will not correct this

What got me looking at this is I have gone to a step of spinning my arrows. Then flo testing. Bare shaft tuning. When I started this I got to looking at how the arrow flexes. This is when I set up a bow with a very stiff arrow and got a weak tear. Noting the arrow was stiff. Then I went to questioning the Easton cart. And what you do to fix and realized it's just a tuning problem not an arrow problem.

You just mixed BH tuning with paper tuning... so you are being a bit confusing, at least to me.

BTW, the tuning guide says it is "behaving" like a stiff arrow, etc. It does mention moving the rest. I do see how in section 14 it doesn't call out what it does in section 8 as far as cam lean, but I really think they expect that you have fixed your cam lean/rest alignment issues in section 8.

[Arrowsmith]

That really didn't answer my question. I understand what cam lean does. My question was, would moving the rest still address the issue?

No. If cam lean is the issue moving your rest to the left will simply move your point of impact to the left. Your arrow will still be leaving the rest offline which in my opinion is unacceptable.

Many people shoot fixed blade broad heads with less than perfectly tuned bows. Many times this is because they need to yoke tune their bow. Since most shooters do not know how to yoke tune or do not have access to a press they simply accept the fact that their broad heads are hitting 2" to the right of their field points at 20 yards and move their sight to compensate. The problem with this scenario is that they are getting less than perfect arrow flight. This will affect accuracy and broad head penetration.

So when you address cam lean, the point of impact doesn't change too?

I get what you are saying. It is better to tune the bow for optimal nock end travel first. The guide doesn't address it. Likely, because if you read it, it just accepts that cam alignment is just part of the deal. Cam lean is expected to be taken care of at the factory/dealer. Kind of like a long bow. The riser is most likely NOT going to be center cut. It likely is not even be the same from bow to bow. With a finger release, the amount of string travel depends on your form, etc. It says it behaves like a weak arrow. It didn't say the arrow was actually weak

No I didn't mix them. I just made a statement. Sorry on that

I agree that they are assuming. But my post was about. That they say a weak arrow with a side tear. The Easton chart states indicates not behaves. So how I see that if it indicates that's telling me they see that as a weak tear. If they did not think that. Then it would not list how to fix a weak arrow.

That was the whole point. Not that a bow is in tune out of tune. Yes it is to get a side tear. But again. A side tear is not a sign of a weak or stiff arrow. That is all I'm saying.

Maybe I need to start all over

A side tear through the paper means you have an elinement problem with your bow. And or grip No problems with arrow.

Where in the guide does it say that? I just looked at the guide on paper tuning. It says clear as day - if using a finger release, it's a weak/stiff dynamic spine issue for a left/right tear. If you were a finger shooter, you'd know why that is. It then clearly says that for a compound shooter, it is an idication of rest alignment or vane contact. It even says to fix it for comound shooters, that the rest must be moved (nothing about point weight, draw weight, etc that is typical for spine issues.) It doesn't mention weak/stiff anything for compound shooting for left/right tears . You have to read the whole thing.

I did its Right here

[enewman]

You have to know how to change an arrows spine. And that is with the things I listed. I might have left out leaving the arrow long or cutting it also

You cannot change spine by moving your rest. There is only one thing on your bow that can be adjusted that will correct spine and that is the poundage of the bow.

Have you tuned a bow/arrow for a finger shooter?

No sir. I don't like shooting fingers it hurts. But I would love to try a recurve some day.

My bad. I totally missed the left tear when I reviewed (notice right tear does not mention spine.)
