Drive 2 nails in a board 26" apart. take a known good arrow and set it on the nails. hang about a 2 lb weight from the middle and mark the lowest point (on the board) of the bend in the shaft. See if the new shafts match the mark. This would be a good approach to use as you are working down the diameter of the shaft. Or Like Sailordad said, make em and shoot em. The weak ones are for kids bows.

Blacktail,

Just do a search here on PA, and I'm sure you'll find an easy (cheap) way to make a spine tester.  I did.  It sure takes a lot of the guess work out of building a set of arrows.

The one I built took me just a few hours...  (And I'm no rocket scientist neather. ;D)


Ok, I did the search for you...

All the Best,
