Wood arrow taper and spine

[Alex.B]

how much, if any, spine would I lose after tapering the  back of a shaft a standard 8" ?(is it 8"?)
I shoot 70-75 parallel. should I get a 75-80 shaft if I want to taper it?
thanks, Alex

Alex.B, my tests showed a loss of only 2 or 3 pounds on average, with a 9-10" taper. Your mileage may vary!

Alex you won't notice any difference.......the majority of the bending occurs in the middle.

My experience has been from zero to two pounds. I don't know why the difference, I guess it depends on the shaft. Either way it is not enough to worry about.

My experience is about the same, a pound or two.  It varies with the length of taper and orig shaft diameter.  Unless you are right on the edge of spine, you will do fine to get your regular spine and taper them.

Recently tapered some 11/32" sitka spruce shafts. Put a 24" taper on them to 5/16". They consistently lost 10 pounds in spine.

24" is a long taper, how do they shoot?  Mine are tapered 11/32" to 5/16", about 11" of taper. On the spine tester a few are no more than 2#s difference and some are no difference at all. I can tell no difference in flight.

Yes 24 " is a very long taper. I made them that way to get a higher FOC balance point. These particular ones my son shoots. Flight is very good...as good as his Redline carbons.
