ipe VS surewood

[ozy clint]

which one will give the smaller diameter arrow at 90+# spine rating?

i want to mount a 300gr stone point on a shaft to shoot out of a 69# recurve.

i want a shaft weight of around 500-600gr but i also want it to be as small in diameter as possible.

does ipe fit the bill? douglas fir sounds like it would work but it will be 23/64" at that spine.
would tapering them be of any benefit?

i'm basically trying to maximise the penetration potential of a stone pointed arrow for testing on water buffulo.

Clint i have to say Ipe or even purple hart.

[Russ Clagett]

Try Braveheart Archery, the guy's name is Tim Harms, and he carries Doug Fir from surewood in the heavier spines, and I believe he might have your spine in 11/32

Not sure........but he does have many heavier spines still in the smaller diameters.......

Worth a shot..........

Do you want a shaft or arrow to weigh 500-600? I think IPE or P.heart will be more than that in shaft alone. I will try to find out for sure on Monday.

Ipe will be double of what you want for grain wt.
Fir should work as will lighter Ash. Ask your supplier.

Have you thought of hickory, My hickory shafts came in at between 600-620 grains in a 65-70 spine.

[ozy clint]

i want a finished arrow mass of 850-950gr. my points are 290gr-320gr. it would be good if i could get get a 600gr 11/32" shaft that would spine right for 69#@28".

it needs to be tough......hafting stone points for use on water buffulo.

Most of the Surewoods in the spine you'll need are going to run 450-550 grains.  Have you considered laminated birch?  Good extra heavy strong shafting but may be difficult to get it in the spine you'll need.  Ash would be worth checking into as well.

I have some full length Surewoods in 100lb spine that weigh in at 575 grains without the tip.  I also have some 110lb spine that weigh 625 grains without the tips.  These are all 23/64 that have a 11/32 point taper and a 5/16 nock taper.

Ozy Clint,

I killed two bulls on Melville Island with Ipe arrows, and was extremely pleased with their performance.

The shafts were 29" long, spined at 70 to 75 pounds, and weighed 700 grains without a broadhead (860 with a 160-grain Grizzly broadhead).

I also hunt here in the U.S. primarily with Surewood Shafts—and love them—but they are not what you want for buffalo.

Go with the Ipe, and use stone that will hold up well to the ribs. Glass-like stone such as obsidian wouldn't be a good choice, but basalt heads, like the old ones I find laying around here in the Northwest, just might be able to withstand impact with heavy buffalo ribs.

[Benny Nganabbarru]

Rik, do you reckon Ipe exists in 95/100lb of spine? And, who sells it? By the way, nice bull!

[lithicchipper]

I'm interested in the dimensions (width, length, width to thickness ratio) and style of the 300 grain stone point you are going to mount. Also what type fletching will you use?

[ozy clint]

they are 3 7/8" long, 1 1/4" wide, 1/4" thick at the thickest part. woody blackwell (knife river)was kind enough to give them to me to shoot boars with and to test on dead buffulo. thanks woody,        

woody told me that he has other designs floating around in his head. perhaps a head 1" - 1 1/8" wide would penetrate better. these offer a great length to width ratio though.
they weigh in at, R-L, 294gr, 310gr and 322gr.
fletching will be 4x 4 1/2" turkey primaries.

 

[ozy clint]

rik- what bow were you shooting those ipe arrows out of? i'm wondering if ipe will be to heavy. by the time i put on a 300gr point they will be at 1000+grs. i'm looking for a finished mass of 850gr-950gr plus if i need a heavier spine than yours they will be more. sounds like the ticket for ben who shoots an 80# bow.

[SlowBowinMO]

Here's an idea, how about some Surewoods footed with a hardwood like Ipe or Purple heart?  Heavy, strong, and some built in FOC too!

[Rik]

SlowBowinMo has a pretty good idea if the Ipe are too heavy for what you are looking for. The Surewood Shafts are certainly straight and durable, and the footing would add the needed weight and strength up front where you need it most.

In response to the questions, my Ipe shafts were from Allegheny Arrow Woods, and were super-straight and durable. I was shooting a 66-inch, 75-pound Howard Hill Wesley Special.

Performance and penetration was spectacular. The first bull I shot was laying on his side in a mud wallow and the arrow penetrated the massive sternum bone between his front legs, went up through the heart and lungs and lodged deep in his spine. WOW! Sure can't do that with a light arrow. When he jumped up and stared me straight in the eyes from only 15 yards away, I thought I'd breathed my last!

I wonder if you will need 90-pound spine with a heavier arrow, as it will absorb more of your bow's energy upon release than a lighter arrow?

[Benny Nganabbarru]

Ah, good point, Rik. Do you happen to know what spines Bill has? Is that first bull the one in the photo?

[2treks]

OK! a dumb question, but, what is surwood? Doug fir?

[Benny Nganabbarru]

Yep, that's right. Surewood Shafts is a business that produces Douglas fir shafting.
