Spining again

[PK]

am I correct to say "Yes Spining Arrows to fit the Bow, Arrows need to be a specific spine weight for the bow being used.Lets say if a bow is 40 pounds at 28" the Arrow Spine or shaft would need to be around 40 pound and 28 to 30 inches in leangth, Approx,meaning that the arrow has to have enough flex in it to curve around the bow when shot.
Since the bow string is centered in the middle of the bow and most bows have an arrow rest that does not reach full center, the string when released does not follow a straight path, thus the Arrow and String are Paradoxing like a wave in motion.
When the Arrow/string reaches its release point, the Arrow is not straight and is in a
flexing motion until it reaches it's Target". I tried to explain this to a person I gave a bow and some arrows to, so I would Like to correct myself if i have given mistaken Information, Because I am still hard to understand at times,LOL, Thanks PK

Yep, sounds like you've got it.
Only one thing, when the string is released, the string doesn't travel in a wave motion, the arrow does, to curve around the handle.

Thanks I like the reasurance But, my understanding was when using fingers to draw and release the string drifts to the left  off my fingers then back to the right. which in turn makes the arrow bend around the bow? This is complicated stuff i'm dealing with but I need to take yer truths serious, since i'm getting older faster or was it younger slower.

The string pushes the arrow straight into the bow. The forces it to bend around the bow, but you should have it only bend so much. You want it to go pretty straight toward the target (it won't be perfecly straight, but pretty darn close). The string is simply going around your finger- it will be pulled straight by your bow.

Arrow weight simply determines how far it will shoot and how hard it will hit. It has less to do with the actual paradox.

Also , depending on the distance, the arrow does stop oscillating before reaching the target--properties of both spine and fletching achieve this. Around 1984 I watched a a series of tapes, high speed photography, put out by Easton arrow Co. of an arrow coming off the bow, both centershot and non centershot models using fingers and release aids. Yes--a bad finger release can effect the string and arrow motion. The arrow absolutely looks like a piece of limp spagetti as it comes off the bow. What was more scary is high speed photography of the modern compound--looks as though the cable would jump off the whheels as the limbs looked loose enough to fall out of the limb pockets--then snapped back to a terriffic amount of force---exactly why the TBB says a string will break after letting go and it hits brace position----believe it

See I said it was complicated but ,Your information is greatly appreciated, really your great instructors and learners.

Very informative, thats why I like to make traditional bows and strings, I only broke one bow because I did not know about grain tracing, I broke one string actually it came unraveled then broke my bow, Bonked me on the forhead too. I only broke 3 bows on purpose because I knew that they would eventually break because of the wood  characteristics. I learned from great Boyer's like the Ones on this here Forum and have not Broken a Bow since. :)Still learnin.

Bows are very simple compared to arrows.  Lots of people can make great bows, but great arrows might be a different story. Justin

No doubt about that Buddy.

I definately believe there should be a "Traditional Arrow Builder's Bible" written some day .

TBB has a section dedicated to arrows, but I agree there could be more info than that. Justin

The early issues of PA had a series by Ken Wee(I believe) about building primitive arrows. Lots of good stuff in all those old issues.     Pat

[Kegan]

I think producing good, solid primitive arrows deserves it's own volume .

PK, "bonked ya in the head?", I'll bet that was probably a shock. Going back to my wheely days I had a 80# compound blow apart in the handle when I let go of the spring--imagine my surprise, holding my arm extended (bow arm) and no bow in sight--one piece flew over my shoulder, the other half ripped off the wrist sling and went under and behind me

Anyway, back to primitive---I shoot a lot of hazel shoot arrows--ever think about how strong they are because of the circular growth rings / no grain run-out? I also don't see a large spine difference on the spinetester when turning them as you do on a split grained arrow. I also like heavy arrows. Kinda got scared off from river cane--had one explode (implode?) coming off my longbow. Don't know if this was a rare occurence or not? 60#bow?

Hey, Ive been reading that but I still Like asking you all questions your easyier to understand.
