Wood Arrow help.

[GraniteStater]

Hey guys, I did a bit of research on this topic.  And have an idea of the problem, but would like to confer with you all.

I shoot a 56" 45@28 (Drawn to 31") so about 54 lbs, Big Jim Thunderchild (center cut).

I purchased a test kit from surewood 3 spines.
65-70, 70-75, 75-80.  I must shoot full length 32" tapered to a hair over 31 inches.

I went out with 125g field point, and broke arrows in all 3 spine ranges.  65-70 it took about 4 shots, 70-75 lasted the longest maybe 10 shots, and the 75-80 lasted 4 shots.  They all broke on target (target is a soft cheap styrofoam).  But the kicker is, I got alot of slight nock right, and nock low.  (All testing was done bare-shaft).

I think I may be underestimating a full length wood arrow and how much it weakens the spine.

Do I need to go to a 80-85 or 85-90 at full length?  Thoughts, opinions?

I really would like to shoot wood arrows, there is something about them.  I'd like to find the right spine and start work on some woodies.

Unless your release is flawless, it's quite likely that you're getting unequal vertical torque on the bow string with a 31 inch draw on such a short bow.  That's one possible explanation for the nock low result.  A nock point that's too low would be another, and perhaps a brace height that's too low.  Although, a too low brace height would tend to yield a nock left from the shaft bouncing off the riser as it passes

I don't bare shaft woodies, but I never pay too much attention to where the nock is in it's left/right orientation, but rather where the arrows hit left/right from where I'm aiming.  If they're hitting where you're aiming, I wouldn't worry about the nock being left or right a little.  My guess is that you're going to have a lot of difficult trying to bare shaft wood out of this bow.  Draw is just too long for any kind of consistency out of a bow that's that short.  70-75# should work. Put some feathers on them and give it another shot.  good luck.

it depends on type of wood and spine. get a harder wood and dont go bare shaft. the longer the shaft the weaker. plus the fletchings help with the paradox, you know that wobble that the arrow does through flight. bending breaks it impact breaks it etc. i match my #s with my spine i also shoot 125gr. field points. good luck.

its a possibility that your bow is twisted.

Thanks for the help.  I know my form is'nt flawless, but have been able to tune in aluminum/carbon with little issues and they fly great.  

I'll put some fletching on em, and see if I can make them work.  

I appreciate your help.

You are borderline between spine groups. I agree with Orion on the 70#-75#'s. With the 125gr tips you should be fine. I would fletch up a couple and shoot them. Tell us how they fly fletched.

I have them sitting in stain now, I'll seal them later tonight.  I'll have the results tommorrow most likely.  Thanks again for the help guys.

I had the same problem with hardwood shafts.65#@29.They were under spined for the 65# but shot great out of a 58#@29
