Guess my spine

[elkbreath]

Vacillating a bit between carbon and wood, as I've only shot one elk with wood, many years ago, and switched to carbon early.  Since then carbon has treated me well on many elk.  But something is drawing me back to wood...

With any luck my friend and bowyer will be done with a super snakey piece of osage in the next month or so and this whole line of questioning will be moot, as I'll have to ask for  different bow!

Shooting a R/D glass three piece longbow, 72# @ 29".  Aiming to use a 300 grain tuffhead and Surewood shaft.

Is this possible, and if so what spine?

[longstiks]

300 grain tip is good for carbon but I think you're going to have trouble finding wood with that high of a spine for a 72#@ 29". I'm guessing over 100, I'd call Surewood and ask them.

I agree with longstiks.  The heaviest spined shaft Surewood makes may not be heavy enough for your set up. Might be able to get it out of 23/64 shafts if they make them. The larger diameter moves the center of the arrow further from the center of the bow, reducing the spine requirement a bit, and the larger diameter means they can get spines heavier than 11/32.

Assuming a 30" BOP and a bow cut to center (not past) I figure about 105-110 lb.  I've built a few arrows for the 300 gr Tuffhead and the heavier head didn't take nearly as much extra spine as I thought it might; only about 5 lb from 225 to 300.  The only real way to find out is to shoot some test arrows thru paper.  I might have some Surewoods in that range.

why would you need that 300 grn head when you will be shooting a log anyway ...    :confused:

you missed some good heavy wood shafts in the St Jude auction

Get a hold of Kevin Forrester and get a set of Red Balaou shafts.

If you're looking at HFOC/UFOC with wood, I haven't seen where many people have been happy with it when they tried it.  It seems that the weight of the wood shaft stiff enough to handle the extra heavy BH negates the extra weight up front.  With carbon you can get stiff spines at low weights and the extra heavy BH puts almost as much weight up front as the shaft weighs.

[Fletcher]

HFOC has its limits with wood, but it still works very well within those limits.  I've had 100 lb Surewoods at 500 grains full length.  That is well on the light side for fir, but a finished arrow at 12 gpp is is still very realistic.

I've been shooting 200 gr heads on lightweight fir shafts for a few years and have been very happy with the performance.  11.5 gpp, FOC unknown, but pretty good.  I've managed almost 21% with wood, but it's more work than I want to do with every set of arrows.

Not wanting to hijack this thread, but figure it is a good place to answer, and may have a similar answer as above.

I am shooting a 65 lb recurve, at a 32" draw, and looking to use my 200 grain werewolf broadheads, which will need a screw in adapter.

I dont have much experience with setting up wood arrows but I'm thinking it's gonna take a pretty hefty shaft for this set up.

[Fletcher]

Yes, its gonna take a stiff shaft.  How deep is your shelf cut?  Most wood shafts are 32", which makes the BOP about 31.25.  The adapter should give you some extra, but will also add to your spine need.

[elkbreath]

Thank you all for the responses!  I appreciate you mulling over my problems.  No doubt I'll be bothering the arrow makers next.  Considering that I'm shooting 72#, if I come out with an 800 grain arrow, that's about what I'm looking for.  

I've never even heard of "Red Balaou"!  Those are seem mean looking shafts.  Thanks for turning me on to that website, the shot where he shoots through granite is impressive. Do you shoot this wood?

[overbo]

I'm guessing your desire for such a heavy BH is for added weight?

You could go w/ a fir shaft footed w/ a hardwood and a BH 1/2 the weight. Your spine issue would be much easier to achieve and the added weight of the footing will possibly get you close enough to your desire arrow weight. It should also give added strength too.

I would also suggest laminated birch. I've made many arrows from this material that finish in the high 700grs w/ a 160gr BH at 28''. They are extremely tough.

[BFreed59]

I believe my shelf is cut 1/8" from center but I will have to check to be sure, and I'm shooting off the shelf split finger if that makes a difference

[elkbreath]

Guys, thanks for the help.

In a similar vein, is there a good place to buy individual arrows, fletched, online?  Especially fmj's?  Or Trad AD's?
