what wood shafts for 69# 'curve with 300gr points?

[ozy clint]

i've been given some stone points by fellow tradgang member 'knife river'        for testing on buffulo (that's water buffulo).

now i need help with a shaft that will work out of my 69# recurve. the points are approx 300grs give or take a few grs. my draw length is 28" to throat of grip. the bow is 69#-70# at my draw. minimum arrow length is 30" BOP.

i have no idea what shaft might be suitable. i'm guessing that i'm going to have to live with whatever finished weight works and tunes best. as long as the finished weight is more than 800gr, it is for buffulo after all and on that note it needs to be tough as i'll be hafting a stone point on the end.

any help would be great, thanks.

I would go with ash or hickory.  Hickory being the toughest, don't know which one will be heaviest.  I would also look at 3/8 or 7/16 tapered back to 11/32.  Can we se a picture of a point.  I have used large stone points for pigs but I put them on a 7 foot dart and threw it with an atlatl.  I think you call it a woomera?  Bill

mistake, these might not get tested on buffulo. knife river might change the design some for that he says. but still need a shaft to put them on.

 

they are just under 4" long and 1 1/4" long.

just about overbo.

Wow       Clint those are nice, sorry I have no recommendations for a shaft.

[Benny Nganabbarru]

Clint, you're going to have to get the heaviest-spined Douglas fir that  www.surewoodshafts.com  have, and then get the footing jig that  www.braveheartarchery.com  sell, and do a little bit of rear-end loading to stiffen it up. You could try building your strike plate out, but my hunch is that it still wouldn't eat enough of the dynamic spine.

[ozy clint]

ben- what weight per inch would they be roughly? is it going to be a mega heavy arrow? i've got a 1000gr carbon arrow and that shoots as slow as i would want to go. i don't mind slow it's just my brain doesn't like the tradjectory. LOL

[ozy clint]

ben- maybe a test pack from surewood would be the go. looks like they will workout good for finished weight.....if they tune up.

i only need 3 shafts so if i get the test pack i should get it covered????
thanks.

[Benny Nganabbarru]

You could get the test pack, for sure. It's just that my hunch is that the heaviest spine they have available will be the one to work with. You'd be looking at about 925 grains plus your "stuff" that you tie the broadhead on with, and that's just with those broadheads, and no fiddling with rear-loading (or front-loading - not sure how front-loading would go with those broadheads) which would be extra.

Make 'em a little longer and you won't need a shaft!

(Or use petrified wood.)

Clint, have you thought about local hardwood shoot shafts. Meadow sweet or red osier dogwood would be a few that should be in your area(Canada). Both quite heavy and very strong and being shoot material no grain violations to possibly splinter like sawn out stock. Also, one of the bamboos should work also.
   Nice looking points you received.

[Bjorn]

A 300 gr point and a max weight of 1000 gr leaves 700 for a 30" shaft-that rules out the heavy hardwoods. Like others have suggested Doug Fir is about it. You will need to build out your side plate even with 100# Fir. A finished arrow with a 300 gr head and 30" shaft will be right in the 800-850 ball park. Take pics!

[SlowBowinMO]

Most of the high spine Fir shafting is going to weigh around 500-550 grains raw for a 32" shaft.  Right where you need to be I think.

[snag]

These Forgewoods are 825gr. with 160gr tips.

The Surewoods with work great for you. They have some 100+gr shafts. I have some of their 95# shafts that I made into arrows with 160gr. tips. I believe they came in at around 750gr.

[ozy clint]

snag- what bow are you shooting them out of?

[Fletcher]

Ozy, I plugged your specs into the spine calc and came up with about 120 lb spine.  If you can drop the point weight to about 200 gr, shorten the arrow to 29" and build the side plate out 1/8", you might get down to 95-100 range.  I have some ramin that are pretty stiff and could get you 800 with a 200 gr point.

I would have concern about a 4" long point breaking pretty easily on a rib hit.  That long a point is going to increase spine needs, too.

[Joseph]

You could get Purple Heart shafts in 120# spine and it is a lot tougher than Fir.  Call Bill at Alhegany Mountain Arrowwoods.  He should be able to help you.   Joseph

Ozy, I've got them tuned up and flying great out of my cut to center Blacktail VL Elite 55#@28"

[ozy clint]

snag- wow that is a suprise to me. seems that spine ranges don't correspond with the bow they work out of very often.

fletcher-i was going to haft them really deep so that the shaft end is only say, an inch behind the the tip of the point. so hopefully that will help. checkout the thread on 'dangerous game' about buffulo with stone points. i've got a lot of testing and learning to do.
