Pat, thanks for the pics!  Unfortunately, the only chicken feathers to survive the winter in the coop are all the big wing feathers.  Huh, and the weird thing is when I sorted them there were over twice as many righties and lefties.  Not sure if they'll work yet.  I need to make some straightening tools like what you show.  What is the saw-like thing on the bottom?  And the gadget with the metal hook and eyelet? 
Crooketarrow, thanks for your post.  I haven't even made a whole arrow yet and I'm tired of agonizing over the spine-issue!
