I remember reading in a past post, (I believe Lil's) that you tune your arrows but slowly cutting down the length of your shaft until they fly true. I have been experimenting, and I got the 55-60 spined arrows to fly unbelievably good. The only problem is, I had to cut them back far enough, that I am going to slice and dice my fingers when I put broadheads on them.
If I am thinking correctly, I should be able to jump up to my 60-65's, and start the process from scratch, and possibly shoot full length shafts. Right? Here's my stupid question. Lets say I begin tinkering with the 60-65's, and cant get them to shoot right. What would my options be?

I got a ROBIN HOOD!!!!!!! I just had my first ever Traditional exploding cedar shaft. The basement has a very pleasing aroma now. My second arrow exploded the first, sending splinters, and all my hard work on my first shafts everywhere in the basement. I'm kinda mad that I ruined an arrow that I &quot;rolled&quot; myself, but Im excited that I got the arrows flying good. Man I love this bow. <img src=icon_smile_big.gif border=0 align=middle><img src=icon_smile_big.gif border=0 align=middle>
Ok, enough gloating on my part, time to make some more arrows. <img src=icon_smile_big.gif border=0 align=middle>

I dont remember where your specs were sitting but one thing to remember each inch you cut off is appx 5lbs worth of spine you are adding. For each inch over 28 you leave it you subtract 5lbs. So if you need another inch, you would jump spine groups by one group and it should put you where you want to be to gain the clearence for broadheads.

Congrats on the Robinhood!

Thanks Lil' and Shrew, I am about to shoot the full length 60-65's. I'll let ya know how they fly. Hopefully I get good flight, at a length that I feel comfortable with.

Ok Lil', here's what I did. I jumped up to the 60-65's, and they are now cut at 30&quot;. They seem to fly the same as the 55-60's, that were cut at 28&quot;. Sound about right to you?
The 28&quot; shafts had the point sitting partially on the rest. The 30&quot; shafts give good clearance.

wow, just re read what I posted, sounds wierd hopefully you understand my rambling lol.

An arrow spined in the 60-65's at 30&quot;es would be equal to a 50-55 at 28.

You will find a pretty wide range of arrows (depending on bows of course), that fly good...there will be one, or a very small window of arrows that flys perfect. The less center shot the bow is, the more criticle the bow is with arrow spine. Also form, the better your form, the more you can get away with as per spine. Guys with really really bad form seem to shoot some heavy spined shafts. The deal is, whatever you do, do it consitently. Reputition is the key to being a successful bowhunter/target archer.

Going by your numbers, the should have shown a little weak. DONT change it if the fly good. Your first go around you may have been close but not on for spine....you might have just found it by not knowing and leaving them an extra inch longer then you really needed. One other thing to consider....when you do find something that flys good, dont forget about arrow weight. It plays into how an arrow will ACT coming out of your bow. Notice I didnt say SPINE. I am not sure how much total weight will effect an arrow but I do know it does. Start jumping weights and you could start seeing problems in the fine tuning section that you'll see more so with broadheads then field points.





I'll try and say this right if I didnt before.

For every inch less then 28 (27 and less) you are adding spine to the shaft in 5lb increments per inch. ie. a 55lb shaft 28&quot;es long cut to 26&quot;es would spine out at 65lbs.

For every inch longer then 28 (29 and longer) you subtract spine by 5lbs per inch. ie. a 65lb spine arrow is left 30&quot;es long, would be equal to a 55lb spine shaft at 28&quot;es.

Lil, my next step is to use my buddy's scale. These 60-65's are flying good, with the exception of 1. It has a little kick when hitting the target. Maybe its an odd ball shaft that was mixed in when I bought them, maybe its one that was out of weight compared to the others. All I know is Im having fun tinkering with these, but is sure drives my wife nuts. <img src=icon_smile_big.gif border=0 align=middle>
Im going to buy a dozen matched arrows next, along with a new taper tool, and see how much difference it makes having matched shafts. I know some of the arrows I have now are off by at least 75 grains, according to the shop where I bought them, but it was all he had.
