Question about cedars and spine

snowman69 · 10-30-2005, 08:59 PM

If I am pulling 55-57lbs out of my falcon what should I get as far as the right spine, weight and type of cedar shafts. I don't have any experience with anything but my carbons. Do I get them sent cut andtips put on or do you have to test different lenghts out to see what flies best. I personnally don't know anyone who shoots them so I need all the help from you guys as I can get. Please be specific and and as detailed as possible I would like to get all the knowledge you experienced shooters have. I appreciate the help

What is your draw length, point weight, string type, and string material?

LBR, my draw length is 29" with around 55-57lbs draw weight right know I use a 125grn tipand I believe I have a fastflight string that came with the falcon. At this point in time I shoot carbons that weigh around 300grns which you mentionedshould be the min I should shoot they fly good for me so I probably shouldn't mess with anything but I sure like the look and how traditional cedars are.

With arrows cut to 30" BOP, probably75-80#spine in POC. Depends on how good your release is, how well the string is made, and how many strands are in it.

Sorry if this may sound stupid on my part but is there a dictionary on this stuff that can tell me what 30" BOP and 75-80# spine in POC means. and why do I want 75-80#spine when I shoot 55-57# don't what to beannoying you but this is all new to me and I just what to know what this all means for my own knowledge and forwhen I go order these arrows.

30" to the Back Of the Point
and 75-80# spine means the same thing in cedar as it does in carbon... the shaft is properly spined for a 75-80lb bow drawn 28"

POC=Port Orford Cedar--that is what folks are referring to when they talk about "cedar" arrows.

BOP=Back Of Point--where you normally measure your arrows to.With wood arrows you have to allow for the taper also (about 1"), so don't chop them off at your draw length.

The spines were measured on a Hill-style longbow as best I can find out, and for a 28" draw length. They require a lighter spine than most any recurve, because are generally slower and cut 1/8" shy of center. There is no chart that will cover every bow, because many shoot differently and are built differently.

You are pulling 55-57#. Add another 5# in spine for each inch over 28", which brings you up to 65-70# spine (you will generally buy wood arrows spined in 5# groups). Add at least 5# for a high performance string material--brings you up to 75-80#. And the Falcon is cut 1/4" to 5/16" past center--this will allow you to shoot an even higher spine than you actually need due to less paradox needed to clear the riser--you might get good arrow flight with arrows spined up to 90#.

These are just basic guidelines, but should get you close. All bows don't follow the rules, how good your release is will make a difference, how well the string is made will also.
