Arrow Shafts 100+ spine

[Half-Rack]

Need some assistance finding wood shafts for heavy bows. Looking for shaft in the 115 to 120# range.

Did not know weather to post this here or in the classifieds section.

Thanks in advance

I have a few fence posts that might work. 120# !!that's impressive.

A good friend shoots long bows 100# plus, working his way up to a 160# bow.

We don't have them in stock but can have them in less than a week.  Top quality Douglas Fir by Surewood.

Thanks SlowBowin

I know that to get that high of spine, ya may have to go through 10,000 or more shafts, to get a dozen. Beware of claims that ya can get them in that high of spine, not that slowbow can't but I know Guru(Curt) shot what he was told were close to 100# spine for a few years and found out they were closer to 85#, when he got a spine tester. They will have to be 23/64ths. at least. Shawn

Shawn, No problems with 23/64" that what I have been  using. I believe that using a sponsor/dealer will eliminate chance for error. Thanks

i know they are not wood but i have some old 2440 aluminum arrows...

put a 1516 shaft inside a GT BG 100 + and you will get what you need...it's just what I use...and they are spine tested !

[Half-Rack]

Thank for all the suggestions, need wood for self nocks

Try some 11/32" Purpleheart shafts. That should get you there. I had a friend that had some 5/16" shafts that were 90-95's, and yes they were spine checked on a testor.

I am using 30" Douglas Fir arrows supplied by  www.surewoodshafts.com  and made up for me by Joe Lorentzen. They are awesome! My bow is a 62" Schafer Silvertip takedown recurve, 80# @ 28", and the arrows are 115# in spine. I put 160 grain heads on them, and they weigh 775 grains in total. They are real works of art, and fly beautifully. I can't recommend them and the fellows who supply and make them for me enough. And thanks to SlowBoinMo for pointing me in the right direction! Cheers, Ben

You should have no problem finding them.

Half-Rack, I've sent you an e-mail.

Thanks all will try some dougfir.

Best of luck finding the right shafts.  I've come across a few in the 110 - 130 range but I doubt I could find a dozen.  One thing you might need to realize is that there seem to be two "standards" for spine measurement and 120 spine from one dealer will not always match 120 from another.  Perhaps the easiest way to make sure you got the same spine every time would be to find an equivalent aluminum size, such as 2413 or whatever.  If you tell the vendor you want wood shafts of the same spine as a 2413 then he can usually find the aluminum shaft and match it.  If you tell him 115-120 spine then who knows what you will get.

Just call or email  http://www.surewoodshafts.com/    if they have what you want, you will get what you want. I can't vouch for other dealers, but I can tell you, you will be happy with Surewood. I have been using shafts made by Doug for a long time. Another source might be   http://www.arrowwoods.com/   Bill has laminated birch and purpleheart and other woods that may get you into that spine range you are looking for. He may be hard to get hold of this week with ETAR going on. Good luck.

Larry, you bring up an important point. Back in the good ol' days, when self bows ruled and spine testers were invented, there was little need for extremely strong shafts. When I went into the shaft business to produce strong ones for modern bows, it became apparent that the spine scale needed careful study. We decided that some raw data was in order, so we put together a bare shaft test kit and made the rounds at shoots wherever and whenever we could go.

We gathered data from hundreds of archers with all kinds of bows, put the data together and did some mathematical evaluation with the help of a computer program. What we found was that the spine scale was a perfect fit to a 5th order polynomial equation. The resulting spine curve was very close to the Adams spine tester through the mid range, but deviated considerably for high spines. The AMO scale was better for high spines, but still not perfect. Our spine chart is based on our data, and works very well for the high spined shafts. On our scale, using the standard 2# weight and 26" centers, a 90# shaft has a deflection of 0.290 inches, a 95# shaft is 0.270, 100 is 0.260, 105 is 0.245, 110 is 0.230, 115 is 0.215, and 120 is 0.200. We couldn't produce enough higher than that to try to market them, but we did make a few 0.190's. The shafts that I'm selling now in the classifieds are based on this scale.

Interesting. With the higher spines the "window" of deflection for a 5lb. group gets a lot tighter then   shafts around 55lb. You almost need a spine tester on 30" centers to open the deflection "window" to have room in your readings on 90# + shafts. My main concern is to error on the side of safety (higher spine) and will have to look real hard at how much the flight of an arrow is compromised if it is 10# over spined with a 100# bow. 10% over would be like shooting a 55# arrow out of a 50# bow.


Thank to all for the help and the different out look on heavy spined arrows.

[Don Stokes]

The way the deflection range gets smaller and smaller as draw weight increases, it seems that at the point that the shaft didn't bend at all with the 2# weight, it could be shot from a bow with infinite draw weight.

Heavy!!
