Title: Spine on cane arrows.
Post by: Scottski on January 07, 2013, 11:59:52 am

I have made a few cane arrows. Never spine them when I make them no spine tester. Is it very important to do so? The seem to fly good.

For cane and hardwood shoot arrows I only use a spine tester to find the stiff side. That side goes against the bow. You can find the stiff side without he use of a spine tester.

I never spined my bamboo, but when I recently made a 70 lb bow I discovered they were all apparently spined a bit lighter than that....so I've had to start doing a bit more work on arrows :)

well right now i have a bamboo backed osage bow 40 pounds. might have to spine them later just to learn how. have to make my own tester. dont like to spend alot of money on stuff i think i can make.

Google "James Hill Spine Tester". That is what I built. I bought the dial indicater for less than $10 and the stand is scrap wood.

I was given some information for the best cane arrow maker out there, and he said to "pay more attention to FOC on cane than spine."  To get arrows to fly and group the same, this is a must with cane because of the natural taper of it.  The taper of cane changes the spine considerably over what parallel shafts do.

Well, been waitin And no one has replied, so what is FOC?

FOC refers to weight distribution, or that's my take on it.  It stands for "forward of center".

More weight in the front.

Ahha. Now that is typical thing with a heavy tip right?  I would imagine it calls for a middle divison somewhere. Of course I am now talking out of my butt. Lol.. I think I even confused myself.

To get arrows to shoot close or like each other, paying attention to the FOC of each cane arrow compared to each other is more important that spine or weight to each other.  Because of the taper of cane, the foc comes in to play more than the other two options.

 I always spine test. To get consistency, at least for me, I think it is so very important. I'm a stickler for matching the arrow to the bow. I absolutely hate to spend hours making an arrow and find it is way under spined or to stiff. I love perfect arrow flight. I took a few hours and made this spine tester and it will dial me in...

IF you don't have a spine tester, look for the leaf nodes and make your nock parallel to the last leaf node.  That should put the stiff side against the bow.

Yep those dial indicators are quick and easy.No math to do or anything.Reset to zero quickly too.
