Hi
I make my own arrows but have no way of testing accurate spine, i buy arrow shafts from a shop that they write on the spine of the arrow, say 35-40 spine.
the shafts are 32" in length, however i cut the shaft down to 28" does that effect the spine? does it change it? or just the weight is changed (i cut from one end only)
by the time i put on my point and nock the total arrow measurement from tip of point to throat of nock is 29" long.
so is my made up arrow still 35-40 spine, its only that bow manufacturers mention about using arrows so many spines over the bow weight and if im chopping the shaft down do i get different numbers at the end, ive always tended to go on total arrow weight at the end to make sure its safe for my bow.
any help would be appreciated
