arrow length?
« on: January 11, 2019, 06:46:32 pm »
I have always used 32" shafts for making arrows for a standard 28" draw length. I've just purchased sitka spruce shafts that are 34" long. Should l cut them down or leave them and just make sure that the bow isn't overdrawn?

what ever shoots well is ok,, I would probably cut them down a bit and testing to make sure they are shooting well,, it will change the spine as they go shorter,, maybe a nice compromise would be 30 inches,,but test one cutting shorter and testing it to make sure it shoots well,,you could go to 29 if you need to make the arrow stiffer for arrow flight,,

The raw shafts are spined for a 28" arrow with a 125gr point. Each inch over the 28" would reduce the effective spine by 5#.  So if the shafts are  34" long they will effectively shoot like an arrow 30# lighter, your 32" arrows 20# lighter from the indicated spine.
I draw 26" but shoot arrows around 30". Like Brad said whatever shoots well is OK.

If you have always used 32 inch arrows and they fly good then that is what  you use. I cut my arrows down so they stick out 1/2 inch out in front of my bow.  But I have been at this for 60 years and am use to shooting that length. I don't like a longer arrow than what I need to shoot.

It's amazing how many people don't know that Pat and it is very good info to know if you wonder why your 50 ld spined arrows aren't flying well out of you 50 ld bow. and you have either left them at 30 or more or cut them to 26 ;) :)

Hell, I've been shooting bows about 70 years, and I didn't know/pay attention to that until I got onto this site!  I just thought it was all "Kentucky Windage"!  Shortened up a set of arrows and will report results when the weather gets a big better.  My arrows were "matched" to a 50# recurve, and shot off that bow, my 43# fg flat bow, and a 50# compound !  I'm still shooting and al, the bows survived!  "Ignorance is bliss"!!

Redhill,
we make those shafts 34" to accommodate folks with longer draws, and absolutely as Pat says- shooting longer arrows will reduce the dynamic spine of the shaft.
dont feel bad about trimming the shafts down to the right length for you.
here is a spine chart, but bear in mind this is for an English longbow-  but it will help demonstrate the sliding scale relationship between arrow length, draw weight, point mass and static spine.
