New arrow time approacheth

[Tarkwin]

The time approaches when I will be investing in some new arrows. I have read with interest the posts re: ACC/Nav/Triples and although the triples seem to be apopular choice, I will be (probably) getting a set of Navigators.

On Friday eve. I had someone measure my draw - to the button, this gave a result of 28 inches, adding the 1.5 inches that various sources recommend gives a total of 29.5 inches - My limbs are marked 34#.

Having downloaded the easton shaft advisor package (see the directory) I ran it and found that the same spine Navs were recommended for the range 24-40# @30 inches - the app. does not allow for 1/2 inch increments.

Is this feasible?

Anyway - assuming that I am drawing the #age as marked, I will require 610s @ 29.5". Making the assumption that the data presented in the table/app is correct, I will not need to replace my arrows as/when I upgrade my limbs.

Hi Tarkwin,

Hmm. I have considered some Navigators too, but for my Compound. For recurve A friend of mine ( Max, a member on here) shot the same spine you have considered 610 at About 29". His bow was a 38lb with about 39lb on his fingers. He also shot FX limbs, probably the fastest limb Hoyt ever made. However they always tuned stiff. the Navigator is a very stiff arrow, The Easton spine charts always seem to be a spine out with recurve. The 710 will be too weak but I know Eaton have started to to make a spine inbetween the 710 and 610. Check this out. I do feel the 610 from experience will be too stiff for your setup.

Regards,

Rich

I really like the Navigators. I shoot the 610's with 85 g screw in points that I may change for break-offs. No problem at any distance with 43# at 27 1/4" and 68" limbs. I have changed to my X7's for indoor work, but may go for Fat Boys next year.

The 540s would work with some heavy points - other wise the 610 and light ones, just pray the wind doesnt blow.

you are prob drawing in the higher 30s on the fingers.

Triples are a better choice than navs for most. But most shops here push the easton way. The 540s are also good incase you up poundage in the near future.

I shot a matrix with G3 and 40# on my fingers and had the same conundrum as yourself ref arrows, I ended up with Navigators because:
1. The Cartel spine charts were very unreliable.
2. There was at that time (18 months ago) more information about the easton product.
3. The retailers were able to offer more input into the decision.
4. I went for the 540 but with 125 grain break off points giving me the opportunity to reduce the point weight when tuning.

As RGS said they did tune up slightly stiff but with the large point this wasnt too much of a problem, I always like to shoot slightly stiff arrows as this gives you room for manouver ref poundage, if your arrows are too whippy you definately have no where to go.

I found the Naviogators very reliable and because of their more robust construction compared to the ACE I didnt smash as many, (you know the scene, strong sidewind, new bosses etc)

In my experiance with recurve
• The Easton charts are spot on
• Point weight makes next to no difference (just leave em full weight)
• Spine is spine.

You need to find out your exact draw poundage and measure exactly how long you want your arrows to be. If they are 28" to the plunger then add 1" if that makes you feel better.
If they are measuring in at 34# 29" then 610's should work well. Just tune your bow correctly.

Nooooooooooo don't do it the 610's will be stiffer than a stiff thing with a speciality for being stiff. Your choice...but they will be stiff. Point weight does make a difference too. Perhaps a 250gn point and they will be spot on.:Not bang:

I bought 610 Navigators and cut them to 28.5" with 100 grain points on a recurve and 39lb on my fingers - bare shaft tuning at 18 yards dropped unfletched shafts 12" to the right (I am left handed), even with the button so weak that the clicker started to push it in. I gave the arrows to another archer with 40lb draw - still stiff. I have since always gone a spine lower than the Easton charts. I think there is a lot of difference between different types of shaft as the length gets shorter. All other Easton shgafts I tried (ACC and ACE) were within acceptable limits and grouped well, despite being a little stiff.

Point weight does affect how a shaft bends when shot (forget static spine weight here). Acelerating a heavier mass causes more compression force on the shaft (Newton's laws). If the centreline of the force from the string is offset from the centreline of the arrow, it will induce a bending moment (archers paradox). In a recurve the flick of the string from the fingers offsets the force by quite a lot, which is why it affects recurves more than release shot compounds (but compounds are not completely immune). A heaver mass point will create an equal and opposite reaction to the string force as it is acellerated. This causes more compression in the shaft and will increase the bend in the shaft, particularly if it already bending (exactly how much is open to experiment and debate).

Erm.........I think that is what I was trying to say, Max are you related to Einstein?

Sadly not! Except for the funny hair, big nose and the squint! When I think about point weight and how it affects how an arrow bends when it is released - think of a bendy stick pushing a light roller skate, then think of a bendy stick trying to push a car - same effect with different point weights, just taken to crazy limits.
