Using Winding Sticks

In a previous post, I introduced winding sticks but did not explain in detail how they are used.

Winding sticks are used in pairs.
If your two sticks are of contrasting colours it is much easier to see them independently. Sticks of the same colour tend to blend into each other making the sighting job more difficult.

One stick is laid at each end of a board or plank, while the user then sights over the two sticks - try to center your view and align the middle of the two winding sticks. (This is why I put center-marks onto my pair of winding sticks.)
Align your view so that you just see the farthest stick sticking out above the top of the closest stick.

On a good and flat board/plank, as pictured above, you will immediately see that the two sticks are aligned. As you dip your view lower and the farthest stick disappears from view, the entire stick disappears from view at the same instant.

On a twisted, non-flat board/plank, as pictured above, the two sticks will not line up. The farthest stick will have an obvious slant in comparison to the closest stick. The illustration above shows a board with an exaggerated amount of twist, but I guarantee you that your eye will see even the slightest twist immediately, if you use these sticks as directed.
