Goodmorning All-- I have a customer that shoots an Austrian bow 70#. The arrows are speced VI+ Strong 8.8mm, I am curios if you can help me to get the AMO spine for woodies?  Thanks to all as I know the answer will get here. Felix????  thanks  DICK @VTAS

.371

Please send the to cheque to the above address ;^)

I don't even want to know what went into translating that...LOL

Thank You  Earthdog ,Call if the check does'nt get there!  Thanks again DICK

I want a check too........  .371 is the deflection in inches equal to 70# and likely not the answer Dick is looking for.  

According to my math 8.8mm is very close to 11/32".  Maybe that is the shaft diameter.  I dont' know what VI+ Strong means.

Maybe thats the straightness factor o.o6 I sure as heck don't know

I am from Europe, but we also work with normal AMO Spine values here.... Put the arrow on the tester!

To change mm to in the conversion factor is .039 x 8.8 =.343 I don't have a calculator so if I did the math right that spine is about #76 pounds. Maybe someone can double check.

Huey, you are right on the math, but since .3465 is also 11/32" I am wondering if it means shaft diameter.

Austrian shafts are done in mm.  So 8.8 is diameter.  I foolishly bought some once, sold as 11/32 and they didn't fit in my taper jig at all.

Crap quality splintering wood as well if it's the same Austrian fir that i bought.  Save ya money and get something else.
