Some new arrows

[jindydiver]

I took a bit of a leap a couple of weeks ago and went out and bought some carbon arrows to try with my recurve and longbow. The guys at Archery Supplies set me up with 6 whitetails and because they know I hunt they threw in a couple of Rhinos for me to try too, bloody champions.
The carbons are amazingly forgiving and I am having a ball now I am using them, also I find they penetrate my target just as far as the woods and alloys I always use. Combined with blunts they are proving to be a drama for the local myna population :lol:

[Sparra]

Gaday Mick...Have you put wieghts in them or are they just standard???
Sparra...

[macka]

Mate good to hear! that looks like it would be awsome fun pegging those little buggers off the back lawn lol. Nice shot robbin hood :wink:

Macka

[PeterM]

Good one!

[jindydiver]

sparra
I bare shafted them and they worked right out of the box so I have left them full length and all
If I had have known carbons would work so well for me I would have bought some ages ago :D

[Sparra]

If you get a chance Mick and you have scales could you weigh one for me and let me know what it is...I was always led to believe that you needed between 8-10grns/bow poundage..ie...55lb bow needed about 550 grn arrow.If they shoot ok and don't damage the bow it sure would save a lot of messing about...
Thanks...Sparra

good stuff I hate mynas.
Just a qick question though,I was under the impression it was unlawful to shoot birds of any kind,is that right or can you shoot them if they're not native.
does that mean crows are ok? actually are crows native?
I wish ibis's were not native .... they are disgusting bin scavenging flying rats and they literally stink.
If you have ever been close to them when their scabbing in parks etc you can smell them and they smell foul.

[Jeffro]

Pidgeons are in disgustingly excessive numbers aswell

[jindydiver]

There is no law prohibiting the use of bows on mynas in the ACT. I can also prove beyond doubt that their use is humane and so doesn't contravene the cruelty to animals act (you just need to look at the pictures).
In NSW if you want to use a bow on birds you just have to be sure their isn't a regulation somewhere prohibiting it (like the crimes act prohibition on killing feral pigeons).

I don’t know where you live Jeffro so I can’t say what the rules would be, but I can say I don’t want to visit that argument again and so it is up to you to check into these things for yourself.


Sparra
The whitetails are 294 grains without a head, and the rhinos are 352 without a head. For sure I will be exploring the weight issue later but for now they aren’t making any extra noise out of the recurve or anything so I am in no hurry.

I hate crows and ibises

[troy]

I only shoot carbons and I weighted my last lost using the uni bush system with small grub screws for extra weight. Had to try a couple of set-ups and see what flew best but I now have the flexibility of carbon with the weight of alloys. Very happy. :D
Ive also heard of guys using cut lengths of heavy wiper sniper cord up the guts of the shafts. Not sure whether they cut set lengths or weigh it but apparently it works???

[Shano]

From memory, the black hawk white tails weigh in at about 9.9 gns per inch. They are tough and, when fitted with a woodys outback hunter, work wonderfully well.

I put them to the test on the weekend just gone (as the pictures show in bowhunter stories) and they are an awesome arrow. They come from the same factory as gold-tip arrows.

Heaps of punching power.

I will be making them my staple arrow hence forth.

Here's a plug for woodys broadheads:-

I trialed a number on the weekend and when it came to toughness and bleed outs woodys came out on top.

I only broke one shaft on the weekend and that was because the outback hunter wouldn't give, so, the arrow had too. A couple of other heads caved in on impact with rocks. A woody would be great with big pigs and it certainly did the job on those goats.

cheers

Great to see technology has cought up with you .I have always weighted my shafts with tubing but I was reading about a guy on tradgang who used cotton rope.

[jindydiver]

I have seen suggestions for weighting these arrows that range from wire to plastic tube to salt and lots in-between. I think I am going to do something really radical and buy the product Carbon Tech make themselves to do the job. I haven’t seen it advertised anywhere here, but seeing as it is in the catalogue I am sure the guys at Archery Supplies can hook me up. :)

[bear]

Jindy,
I've also seen some tubing in the 3rivers catalogue designed for carbontech & goldtips to add weight. It came in 2 different weights 2grns per inch & 3grns per inch I was going to get some as it would be much more convenient than everything else I've been using and bring my arrows to the exact weight I'm after :D

Does anyone know if/how weighting with tubing effects spine?

I have some 340's that I originally thought would be ok (or at least passable) with my bow but it turns out they are too underspined for my set up.
They also need a bit more weight so if weighting with tubing will stiffen them then I'll do that and avoid having to sell them and buy new lot.

Cheers!
Jono.

I believe that full length tubing inside carbon shafts has little or no effect on the spine. This has certainly been the case during my limited experiements anyway.

If you want to soften spine, you add weight to the front. If you want to stiffen spine, you add weight to the rear. If you add weight to the whole of the shaft, the spine should remain the same.

Having said that, it is possible that the insert will effect the spine, making it slightly more stiff, not because of the extra weight or the distribution of that weight, but because the actual insert material itself has some stiffness to it and that stiffness could increase the overall stiffness of the shaft to a small extent.

I would suggest you try adding weight to the rear of your underspined shafts in a bid to increase the spine. You can buy weights for this purpose.

MIck I have found the opposit with the tubing in the shaft the extra mass slows the reaction of the arrow so the DYNAMIC spine is softer even if on the spine jig they are the same.This is what I have found anyway and I need to use a shaft stiffer than rated in the charts when using tubing in the shafts.
Cheers KIM

[Mick Smith]

Well Kim, if you're right, that will blow away Hefty's chances of increasing the spine of his shafts by adding inserts.

I based my conclusions on just a couple of experiments whereby I shot some carbons from a variety of bows with inserts and without inserts. Apart from the arrows with the inserts striking the target slightly lower, I could detect no difference to either the arrow's flight or point of impact.

It's an interesting subject and I'd like to know more about it. :)

Mick

[Kimall]

Yer Mick it can be very confusing at times when adding weight.Carbons seem to have such a broad spine range that if you are in the middle of that range adding tubes may not really make a big differance but at other times it will make arrows that flew ok unusable when they have rubber tube in them.I have always found they softened with tubing not stiffened.
If you add cresting paint that will stiffen a shaft more than most relise.
I had some woods bare shafting perfect and put cresting and feathers on and they all turned out to stiff. :x The beauty of using carbons is when you get it all worked out you can make another set of arrows at any time and know they will be the same. :wink:
Cheers KIM

[Hefty]

dang :( Seems I might need to sell em and go a bit stiffer....







































THE ARROWS!!....you dirty, dirty people :lol:

[Luke]

ah well... it happens... :?

[Kimall]

Mate what is the length like if you can safley cut half an inch off that will make a fair bit of differnace making them stiffer.
Cheers KIM

[Luke]

He needs a 32 inch draw mate :shock: doesn't give much to cut off :lol:

[Paul R]

My experience has been the same as Kim's.
I put some fly screen tubing in some carbons to make them heavier to use with my recurve and as a result the dynamic spine was way to weak and I couldn't use them. I used to shoot these same shafts unweighted out of a 70# compound and they were perfectly spined and flew great when bare shaft tested. :?

[Kimall]

Sorry I must have missed that bit before no wonder they are a bit soft then at that length. :wink:
Cheers KIM

[Shano]

Hefty,

Either cut your arms off at the elbows and reduce your 32" draw length or see if you can wind the limb bolts back to the minimum appropriate level.

I can't recall if your limbs bolts are maxed out or not.

I do know though that 75 # is what your bow measured at yesterday and, well, there ain't no buff in the new england ranges :lol: (however, I do believe I have stumbled across some wild cattle that I have been given the nod on :shock: )

Good luck :D :D

Hefty

Have you tried reducing the weight of your points? A lighter point will have the effect of strengthening spine. Of course this will only work if you are currently using heavish points, as you will need some margin to reduce the weight for this idea to work.

This concept worked for me recently. I bought some nice Silverwood shafts, but they turned out to be slightly underspined for the bow I wanted to shot them from. They were originally fitted with 125 grain field points, so I took them off and replaced them with very lightweight 70 grain ones that I had on hand. Now these arrows shoot reasonably well. At least they are useable, even if they are a bit light and poorly balanced.

Mick

[Luke]

I think Hefty's already using 115gr woodies on them :shock:

Luke

[Hefty]

Thanks Shano, yeah I've already wound them down another full turn which should put it at about 70#. It goes down to 65 but I don't want to wind them all the way down myself in case I go too far.

Mick, I've thought about smaller points and/or weighting the back but at this stage I'm really going for simplicity as well as keeping my costs right down (I've been buying all sorts of gear for my first hunt).
I figure if I can sell these ones and get some 300's I won't have to outlay too much more and I'll have less fiddling/tuning to do and more time to practice.

[jindydiver]

I dropped into Benson Archery on Friday and bought some weight tube for my arrows. The weight of the rhinos is now 445gr without the head so I am sure they will be fine now for drilling everything I hope to with them. They still fly like beauties with the weight in them too.
