Do you spine test your own arrows.I am usedto do that and this explain why some arrows fly crazy.Also some lots of carbon are not really consistent in spine.When i hunt I want to be sure I get the best,for practice I can use blems too.

No, but I should,I have faith that they are what they say they are.Time to but a spine tester!

Test every shaft with the 'spine-o-meter' made by cupcake. It is terriffic!

Test every one with my old Scheib.

Yes, it is hard to get good wood shafts and I like to check weigh and check the spine.

I think your right about some carbon shafts, the spline needs to be aligned with the nock the same on each arrow.

I test each and EVERY shaft no matter if it's wood or carbon....I also Use the "Spine-O-Meter".
You would be surprised how many shafts are miss marked. (both carbon & wood).....

I check them all with a Ace Spine Master. Hap

it is the toughest thing about archery IMHO.

Absolutely!

Yes, ever shaft for wood and carbon.  AL is always right on so I don't bother (2117=73, 2216=83# etc).

Nope. I buy hand-spined shafts from Surewood.

No. not carbons. I shoot Easton/beman and have never had spine issues with them.I have checked lots of carbons in the past but no longer need to.

Yes I do, spine and weigh ea. one and write
on the arrow next to the cock feather.

I just set up my Ace wall mount model in my shop in the barn.  I was about 5# heavier than I thought my shafts were on each dozen.  I asked the Ace folks at Kalamazoo and they told me I would be heavier in the winter because of the cold in the non heated shop.  I feel better now.

Do you think they were saying a particular shaft would spine 5 lbs heavier out in the cold (condensed wood cells) as compared to being in the heat or you would need a shaft 5 lbs heavier in the cold - or are these the same thing.

Yes I test the spine on every wood arrow I get, after getting a spine tester it really seemed silly not to have one if your going to shoot wood shafts. Some groups are not so good and if you buy bulk groups you have no choice.

I test every wood shaft, I dont care who produced it, they're all human.

You set there and hand spine a couple hundred shafts, its such a repetative task, some "squirrels" are gonna sneak through.

Spot on Eric!

I just use an Ace wall mount, it seem pretty darn accurate for me, consistent most importantly.

You can "calibrate/check" most any spine tester with a few aluminum arrows. You get the 28" deflection from Easton and put that in the conversion table on Stu's calculator and it will tell you what you should read at 26".

I've gotten #5 dozens that are really #8-12 spreads, from the "best in the business". Thats why I check'em all. Not really a big deal for me, but at least I know to cut them a little longer/shorter at the git-go.

Eric

I test every wood arrow I make and a lot for friends.

I don't spine test any arrows.  What I have started doing is.....numbering each arrow (I get the very small stick on numbers from LAS).

If there's one in a group that's a "bad apple", it'll become evident.
