Title: wood equivelent for aluminum
Post by: portugeejn on July 04, 2007, 01:15:00 AM
I just got a a Martin Savannah that I would like to use for hunting season this year.  It pulls 51 lbs. at my 27" draw (measured with a scale).  It shoots Easton Legacy 2016 shafts cut to 28" 125 grain points 3 each 4" parabolic fletch like darts-really well.  

Great, except I really don't like the noise aluminum makes and would rather shoot wood 5" shield 125 grain point.  In the words of a good friend "it sounds like you're shooting conduit."

I would like to make up some wood arrows for hunting season (starts August 25) but I don't know what spine will perform best, in light of the aluminum performance.  All my wood arrows are 45-50 and corkscrew some before they settle down and fly straight.

Anyway, what I would like is some suggested wood spine weights, as I don't have time to build and try a bunch of different shafts (let alone the cost).  Thanks for your suggestions.

Within the next month I will be ordering some Sitka spruce shafts from Hildebrand's for my 51#@27" Dwyer.  These arrow will spine at 60-65lbs and be cut to 28.5"  Neil was right on with his spine suggestion of 50-55 lbs for my 43#@27" Dwyer.  These arrows are cut at 29" and I get excellent flight.

2016 has a "static" spine of a tad over 60lbs. That seems a little stiff for your setup but if it works, go for it!
I have a 55lb recurve that shoots 2115s perfectly (70 spine) go figure.

You might want to take a look at 3rivers.  I think they have a "kit" where you can buy several different cedar arrows in different spine weights.  You could also contact some of the sellers of shafting and see what they suggest.  Some of them may make you up a sample of different spines so you could see for yourself.  What works for me might not work for you due to differences in form,etc.

55-60 or 60-65, depending on which end they are closer to spine wise. I would try a 55-60 first.

An XX75 (Legacy) 2016 will static spine at 62 pounds.  I'd start there with the woods left a tad long.  Shorten them some to stiffen if need be.  Shoot them thru paper if you really want to know how they're flying.

I believe Vermontster13 is in ballpark...either 55-60 or 60-65 spine should work from your bow.  But for broadheads I'd lean towards the 60-65.

Just a thought here, the aluminum arrows shouldn't be making any noise. I sometimes have one bang the strike plate as I put it on the string, and if a point is loose, I can hear that as well. Otherwise, they are as quiet as wood.

Good luck in your search for the wood that suits your bow. I shoot both wood and loonyums, as both have their merits. There  is  a certain satisfaction in crafting a wood arrow that I don't get from merely fletching up some Eastons.

I have spined 2016s at 59.5 lbs. on the tester I have been perfecting the last few months.

I have also calculated the expected spine from the Easton deflection data by converting it from the ASTM measurement standard they use to the AMO (ATA) standard that traditional archers use by using beam deflection theory.  The calculated spine is 59.3 lbs.

I have seen numerous reports of 2016 spine being 61, 62 and 63 pounds, but I disagree based on my research and test results.

For your set-up I think 60-65 is the right woodie.  But, in the field you may draw short in a pinch and want a 55-60.
