- In this video I describe what arrow spine is and why it's important for selecting the right arrows. I demonstrate how to check spine on a wood, carbon and aluminum arrow shafts. I use a Spin Spine tester from Ace Archery Tackle and a Bearpaw Spine Tester 2009.

Hey Andy - I've noticed that i get variations in spine (from test to test) if I orient the arrow with grain vertical each time. I then realized that the shaft is rotating slightly when the weight drops (I too have a Ace Model 107). I now mark the top of the grain and insert into the tester and then make sure it doesn't rotate at all when the weight drops. Just wanted to toss that out there. Also want to encourage you regarding your videos. I absolutely love watching these so thanks much for taking the time out of your day to put them out here!! Kindest Regards, Andy
Great video! an excellent job Andy, thanks for sharing your knowledge.
Awesome video. I love when I find information that teaches me ALOT about something I am interested in.
Subed and will be checking out all your vids.
Thanks
Thoroughly enjoyed your video on measuring arrow spine, @AddictiveArchery! Your explanations were clear, and the visuals greatly aided understanding. It's evident how vital selecting the correct spine is for optimal arrow performance. Newcomers and experienced archers alike can benefit from this refresher. Looking forward to more content like this!"
Liked and subscribed. Thank you for showing how easy it is to operate these readers. I 'knew' about spine testing for wood arrows, but hadn't realised that carbon and aluminium (I'm English), suffered the same thing with rotation. I may have to re-check my aluminium arrows....
Excellent video!
I really like your videos thanks for doing them.
BEST easy to follow technical info!!!!!!! 👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼❤️
Great explanation thanks!
Super job. Nice.
OoohHH YeeaahH, that was insight, no way, just like a fishing rod you can spin, "Click," an arrow to find the spine?
Unreal Andino, ive found a wealth of info today, You Beauty Mate.
great job..... I learned something. thanks
Those name-brand spine testers cost a small fortune. Most guys who go to these lengths to fine-tune their arrows probably already have the tools and know-how to build a home-made spine tester on a budget.
Great video! Thanks!
Thank you
Thank you again.
Great video. Thank you. After now 5 years, what is according to you currently the best spine tester on the market for both wooden and carbon shafts?

The ace spin spine in the video is still the best and most accurate in my opinion. I have tried some of the new electric ones. I still like the Ace better.
Thanks for the instructional vids! Are you familiar with the float test to find the stiff side of the shafts? If so, does the stiff heavy side lay against the riser? Thanks again! Joe
ole mariner Hi Joe. I’m not familiar with the float test. I’ll have to do some research. You want to get the stiffest side of the arrow up against the riser. On a properly made wood arrow shaft I have not noticed enough difference between the two sides with the grain oriented correctly.
Great info
I’m so confused though. How do I know what I’m looking to have spine weight be on a cane arrow w a 50# at 20” draw?
I wonder what spine cedar shaft I'd need for a 45# black widow PMA x they tend to like a stiffer arrow
Great videos. I'm thinking about buying some wood arrows for my centaur longbow. 50@27. I'm currently shooting a Easton axis traditional arrow cut to 30.5" with a 200 grain point. Draw length of 27in. I was looking for an arrow length of 29in and point wt of 125. What spine would you recommend?
Stick and String just replied to your email.
HI Andy... I want to say I love your work and hopefully I will be able to shoot one of your arrows someday. I use thumb draw technique. and I want to built some barrelled arrows similar to Turkish target arrow I have search all over trying to find information about how the shaft tapering would effect the spine. and what spine value I should use with a barrelled arrow. I couldn't find anything unfortunately. Do you have any knowledge on it, any experience with barrelled arrow shafts? Maybe I will start doing myself research on it. I appreciate any response. Thank you so much!
Hello and thank you for watching. If you stay out of the center of the arrow shaft with the taper it should not affect spine.
@@addictivearchery1123 Thank a lot for the fast answer! My plan is to use 32 inches 11/32 shafts and the front 1/3 tapering to 5/16 and also the back 2/3 to 5/16. similar to Ottoman and Manchu arrows. My bow pulls 48lbs at 32 inches. So I will start with 32 inches 11/32 indexed at 65´70lbs spine to be on the save side. I rather have a too stiff arrow then a too soft one.
Should spine testing be done after shafts are cut to length? I think once u cut them the spine readings will change.
I watched the video but hopefully I didn't miss this if you already mentioned it but what if your arrow is too stiff for your bow how does that affect the performance of the flight of the arrow? Same goes for not stiff enough. I know you said that the spine of the arrow is affected by more than just what spine is made for a certain weight but I want to know performance when it's flying through the air.
Thanks
If you shoot left side of the bow and arrow is too stiff then arrow flies to the left. And if its not stiff enough then it flies to the right.
And If yore shooting in right side of the bow then it’s the opposite.
Your videos are great, thank You! I have a 91 pound 28 inch draw longbow... where would I find info on what shafts I need, or where I can get the shafts. I'm a little lost, please help
Jason sorry for the delayed reply, summer has been a little crazy so far. I can help you with the shafts. Shoot me an email. Addictivearchery@gmail.com
I had a buddy his woods would snap at the target right at the point because of under spine that 90 plus with wood is tuff good luck 👍
7:25 victory arrows have a stripe showing the user where the overlap is
Is it okay to use a string loop on a longbow and a release just wondering I'm disabled and have very little hand strength still like to shoot when I can thanks.
michael hopper yes you can. Just realize, there is no let off on Traditional bows so the “recoil or reaction” will be much more due to you having to hold more weight. Other options would be a mouth tab or thumb ring if your disability allows.
Good video thanks..what state are you located in
Ralph Anderson I’m in Gervais Oregon
Sir, with a compound bow the heavy part of the spine should it go on the rest, thanks
bearnard blackwell if you are shooting fingers it should be facing the strike plate. If you are shooting a release it should be up.
I’m trying to figure out how heavy of a point I need on the new wood arrows I’m building. I’m shooting a 40# at 28” longbow and I bought 5/16 arrow shafts. And I’m only pulling 26 1/4” Thank you in advance
125 grain is the heaviest point I know of in a 5/16 diameter. Typical weights are 70, 100, and 125 grain in 5/16 diameter. Call or email me and I can help you figure it out. Thanks for watching.
@@addictivearchery1123 thank you. I sent an email
another question regarding carbon arrows: how does the GPI relate to spine? i purchased some "350 spine" arrows. tested on jewellers scales and they came up 7.6 GPI despite being advertised as 10.1 GPI. fishy?
Manufacturers have different tolerance for what they let out. The more you spend on the shafts the closer to spine and mass weight all the shafts will be.
Shafts with graphics tend to be a little heavier.
Hope that helps.
I shoot 500 gt trad. Arrows 26 in to the bop. 150 gr heads 4 and1/2 in fletching. 63.3 lbs at 26-inch draw . What wood spine?
Hi Micah, a 500 spine is equal to a 63 pound wood arrow spine. In order to get you the correct spine I need some more information. I need to know what bow your shooting in order to determine how your shelf is cut? How long do you want your arrows to be? Does the bow have fast flight or a Dacron string? Feel free to email or call me. Thanks for watching.
so 350 spine carbon arrow should deflect 1/350 of inch (which is 7mm) over 28 inch span? please correct me!
You are correct
do you sell bows too???
Alex Dunning I have some used bows in stock.
Addictive Archery do you have any yew wood longbows?
Alex Dunning no but I may know of some one who does. Contact me through my website and I’ll give you their info. addictivearchery.com
Addictive Archery is it okay if I am only 13? and can't get you the money yet
how much would gray shaft half inch arrows be with a broad head for a 42 inch bow 18th 25 pound bow be
Where do I order from
Addictive Archery what spine would I need for about 47 lbs I'm on your Web site now just need more info before ordering
American Mastiff its best to call me. There is a lot more info I need to figure out what spine you should shoot. I need to know your draw length, point weight, riser design and string material. These all affect dynamic spine.
Addictive Archery just sent you contact info on you website
What is there not to like ..TU
and nothing on aluminum arrows
Poor sound quality, sounds like your in an echo chamber. Hard to understand most words.
Great video!
Thank you.
