Side nock?  Can it really matter that much?  Seems to me like if it was twisted to the left then you'd want the left nock to be deeper.  Don't go cuttin' until you get more input though. lol

Hey Dennis - I'm thinking that would be used more to correct string alignment than twist, ...but if you were doing it for twist, I'm pretty sure the cut out notch would have to be on the side of the limb that tilted toward the archer at rest allowing the side that tilted out to be pulled a bit more inward.  Basically, you're using the width of the bow as a lever to unwind the twist.

Check the thickness from side to side of your limbs and you will fine one side thicker than the other. Remove wood from the thicker side of the belly.

Cutting the nock deeper helps track the string better. If the string is off to the left cut the left nocks deeper.

Basically, if the stave is naturally twisted for 30 degrees or less I don't worry about it.

If I caused the twist by uneven wood removal than I fix it.
Remove wood from the  high side or strong side in the strung bow. The high side would be the side furthest from the string.

I should mention that in the last yew bow I built I took pains to make sure my wood removal was even. The stave was a gift. I even used calipers.

However, when I strung it it was twisted anyway. Wood is not uniform. I

I fixed it as I described.
