I'm wanting to start shooting cedar arrows. I have a 30 inch draw. My Longbow is 55#@30. I heard I should shoot a heavier spine because of length. What weight would be best.

What is the centershot (the way it's actually set up), the overall arrow length you want, the string material you are using, and the head weight you want to use?

I am from Ohio also. I shoot a 45# Montana, at 28" The draw length is 27 1/2"/125 broadhead& field points. My arrows are 11/32nd tapered cedar/with a 29" arrow length. They are spined at 50/54 lbs. I mostly use the standard wood arrow chart,BTW, the string is D97 from 3 rivers. I get my shafts from Lost Nation Archery , i Styrges, Michigan.

He has straight shafts also. You will not find a reasonably good wood arrow or shaft , that is cheap. I wouls call Lost Nation and talk to Larry. He won't steer you wrong.

Tell him, Mr.Griz, from Perrysburg, said"HI".

Also T.J.Conrads, from TBM, magazine has a chapter in his book all about crafting wooden arrows.

Enjoy this stuff. It can be frustrating and fun at the same time. Go to the Compton Shoot in June . there will be multitudes of people there you can talk to .

5# for every inch over 28”, 5# for FF string, 5# for over 125 grain points. Basically what Shawn says. I forgot R/D bow, add another 5#. I cut my shafts 29” for my 28” draw at 55#’s, my R/D LB likes 65# spine shafts.

Braker1: Wood arrows are spined and measured at the AMO standard of 28". So if shafts are designated as being 50/54# its @28" but the shafts will be 31"to 32" long as they come from the supplier, they only spine 50/54 when cut to 28" BOP, they will infact loose 5# of spine for every inch they are longer than 28". At 31" they will spine 35#; if there 32"long they spine 30#.

If your bow is 55#@30 inches you will probably want a 31" arrow if shooting broadheads or 30" arrow for field points. Now since spine is expressed at 28". you will want to calculate the spine needed at those arrow lengths. for a 30" arrow you need to add 10# or 60/64 spine at AMO standard or 15# for a 31" arrow 65/69 AMO standard.

Those values will change if your bow's shelf is cut too center (If it is, add another spine range to those figures)Most longbows do not go past center on shelf depth. Whether the bow is R/D or not makes absolutely no difference. If the bow has a non-Dacron string add another spine range,(65/69 for 30" or 70/74 for 31" arrow)

And 5lbs, for every 1/16" change in centershot.

Thanks very helpful. I'm shooting a Dwyer original.

aromaker has made me several dozen arrows and all spot on.

So if arrows are spined at 28 in then why are all the spine meters using 26 in .

They are measured with arrow supports 26 inches apart to give you a spine rating for a 28 inch arrow.

Ok explain how that works

Ok explain how that works

Wooden arrows are spined across a 26" span with a 2lb. weight. The standard for ever has been that the deflection measurement obtained in this manner is applied to a 28" BOP arrow.

It wrks like that because when the guys made the chart originally, that's how they set the standard.

Ok

Shawn: Yes wood arrows are spined between 26" centers with a 2# weight but the resulting deflection given gives you the spine for a 28" arrow.

What has made all of this confusing is the new ATA standard it uses 28" centers and gives you the spine for a 28" arrow. The person that devised the ATA standard knew nothing about spine and should be tarred and feathered.

"The person that devised the ATA standard knew nothing about spine and should be tarred and feathered."

And to follow that up, few people, even today, understand what spine is and how it is affected/effected. It was pretty much common knowledge at one time. Simple things like brace height as well...no matter how many times you tell people it's a variable, they still want a number.
