Some of you saw the write up on the 70 year old 15# longbow I got yesterday. I'd like to try it with some appropriate arrows, but spine that light is hard to find. I'm wondering if anyone knows the spine weight for Eastons below 1616? I'm sure I've seen some listings for Easton arrows down in the 14 and 15 diameters.

I would get some ramins (sp) dowls and get them to spine... I doing think Easton makes anything small then 1616's
Sorry I was wrong.. Target Platinum (http://www.eastonarchery.com/products/product/29)
did some research.... interesting stuff
Easton offers these sizes in very light weight:
1214 with deflection of 2.501
1250 with deflection of 1.250 (actuallly disproportinately stiffer)
1413 with deflection of 2.036
1416 with deflection of 1.684
1516 with deflection of 1.403
1614 with deflection of 1.153
1616 with deflection of 1.079
I have some 1616's and tested them in two spine meters. I got rough figures because they aren't really the best at that light a weight, but they tested out at 29# and 31#. I'd love to try spining some of those lighter ones. I'm thinking the 1413's. I think they might work well at 15# on a non-centere cut bow. Be fun to find out.
If anyone has shot any of these skinnies, or set them up for youth to shoot, I'd be real interested in your results.

Dick,
For aluminum and carbon arrows the spine is easy to calculate. Divide 31.5" by the deflection Easton lists and that will give you the spine in lbs. the same as a woodie.
A 1516 is 31.5/1.403 = 22.5lbs.
I have verified these calculations with measurements. The Spine-O-Meter will measure shafts down to 20lbs and I have tested 1516 at this spine.
