Anyway to get determine the stiffest side of arrow fast and easy? A tool of some sort? Without throwing arrows into bubble bath or putting through hooter....

Methods?

Some folks use a compression test. Get a bar clamp longer than your arrows. get a couple short flat pcs. of aluminum. Hone divets into the middle of them and screw them onto the ends of your bar clamp pads. Take your arrow with field point in one end, remove nock from the other end and put in bushing and field point, so that you have field points in both ends. Place field points into the middle of the divets in the flat metal and simply squeeze the clamp til the arrow bends. The stiff side/plane of your arrow will always be at 90 degrees to the way the arrow bends.

Spine indexer, go to the diy section can build one or buy em from Lancaster or 3rivers. I found tub way not to be effective.

Tested this pretty extensively last year. Doesn't work. Couldn't get repeatable results to save my life lol. I bought arrows from SouthShore archery that were spine indexed and never could get the compression test to line up with the mark they provided.

I use my bow press, works great

Ram spine tester, or a version of one, will work well for finding the stiff/weak side.

I put one together from aluminum bar stock, skateboard bearings, and a dial gauge and stand.

Haven't had to turn a nock at the range ever since.

X2 on the spine tester.

I built one a few years ago using bits and bobs I had lying around.
I made mine adjustable so I could test with different arrow lengths apart from the standard 28''.
If you just want to index arrows, length does not matter.

That is slick! You should put together a tutorial on how to make it!

Last chance has video on it that the way I do it with bow press

 

[enewman]

Compression. Dosent work
Floating dosent work
Ram testing
Flo testing
Freq testing
I've done all but freq test.
The only true way to index is dynamiclly. The only way to do this is shoot them

Nock tuning with a bareshaft.

Second that.
