Arthur- I didn' t mean to imply that you didn' t know how to find out that information, I know you do and I apologize if it came across that way. I agree with your post 100%.

I too find that some factory ends are less than desireable, so if I' m making some 28" arrows from 32" raw shafts, I' ll cut 2" from both ends rather than cutting 4" from one and and leaving the other end as is from the factory.

Also, the " straightness" spec from the manufacturers is really only good at that center between the 28" span. I suppose this assumes that the shaft has imperfections in an arc-like fashion over the length of the shaft. Then the greatest runout will be in the center. What if the shaft has a more S-like imperfection? Then the center reading may indicate just about perfect, but the ends are going to be all over the place.
