50-55# cedars equal what size aluminum???

[skychief]

Quick spine question...

What size aluminum shaft corresponds to 50-55# cedars?

How about 45-50# cedars, while we are at it?

The cedars I am shooting now are 29 1/2" bottom of nock to back of point (125 grains), for what it's worth.

Thanks for any help, Skychief.

2016 and 1916

Hard question to answer, but, 2016s would be close.

For the 45-50, 1916s would be close.

Not exact, though.

I'd say lighter. On my spine tester 2016's spine 63lbs. 1916's spine 52. This is amo spine.(2# on 26" centers). So 1916 matches closest to 50-55. 1816 would be the closest to 45-50. But remember, dynamic spine is different than static spine.

Dynamic spine is my main interest.   Looking for aluminum that will mimic the flight of these cedar spine ranges.   Don't have many aluminum shafts for experimenting, so, appreciate all the help guys.

I shoot 50-55 in several of my bows. I can shoot 1916's in them but I usually need a little more tip weight to get them to tune, both w/ the same arrow length. ie; 125 on the wood, 150-175 on the 1916's.

It can depend on the bow, I have had 55 pound cedars shoot fine out of a longbow and a Bear Super K, then find that the 2016 acts stiff with the longbow and fine with the Super K.  Now I shoot 1918s out of all of my longbows with different adapter weights to suit the different bows, they have a slightly slower recovery rate than the 2016s.

Thanks for the help.  Anybody else have something to offer?

Thanks again.

45# = .578 deflection
50# = .520 deflection
55# = .473 deflection
Use this link to look for aluminums in that spine range....

Short answer? 2016, left long (fulll length), cut 1/2" at a time to check for tune.

I shoot 50-55 woods at 27.5" BOP with 125 gr up front, and I shoot. 2016 27.5" BOP with 125 up front from the same 4 bows x

Here they are the perfect match. YMMV

Remember too that different diameter shafts may be affected differently by the cut of the bow, meaning the same spine (deflection) shafts might fly differently.
