When using double nocks, to prevent the arrow from sliding down the string after release, how close should the nocks be toward each other? It seems to me that if they're close enough to do what they should, wouldn't they pinch in on the arrow nock at the end of the power stroke? Appreciate any answers.
I leave about 1/8" extra between the nock points.
I usally make mine to give the arrow nock about a 1/16" to 1/8" clearence.I don't want it to pinch the arrow nock as I draw it back.
I use dental floss for mine, just enough space between them for the nock. Been doing it that way for about 40 years. Never thought about the power stroke.
When Rod showed us in class I believe it had about 1/16" of play. That is what I use on my bows.
Like others have said: 1/16" or so, just enough to prevent nock pinch. An easy way to think of it is about two or three widths of serving material.
Thanks all. I use tie on nocks & was just curious.
I use two string serving nockpoints about 1/4" apart. This gives the arrow clearance to stay nocked on the string when I draw 32".
The new Trad Bowhunter has an article about double nocks, using serving on the bottom and leaving a space so the arrow nock won't be pinched.

This is JUST my opinion. I am not going to claim I am right, but I will say it is what I believe to be true.
IMO, nock pinch matters if WE do it, as when we do it we put pressure on the arrow in a way that we torque a shaft. A pinch on the nock though caused by nocking points (especially tie on ones), isn't going to matter since it only pinches the plastic nock...and would do so in an evenly distributed manner and therefore would not torque the shaft. All that pinch does is "lock" the arrow into position...and by the time the arrow approaches brace that "lock" is of course released. With metal nocks I would be more concerned about it as metal may crush the plastic nocks and may perhaps crack them. Additionally, if the archer shoots split finger, they do hold the string open somewhat.
That said, I myself only use one nocking point on my bow; however, I have my kid's bows set up with double nocking points so they don't accidentally move their arrow down. When I tie on the second nocking point, I put a spare nock on the string and tie to fit...not tight or squeezing, but just to barely contact it. Once I am finished, I watch them shoot to check for proper arrow flight...and adjust it if necessary.

I agree with Lee, When the string gets to brace at the shot the pinch will be the same as the way it was tied. I tie above and below and have them snug up to the nock and it works good. YMMV
Take and set you top nock point, then take your arrow while on the string and the bottom nock point not tight, swing your arrow around the back of the string and push the arrow up on about a 45 degree. That will slide the bottom nock down just the right amount of clearence. Tighten the bottom nock...Done

That's exactly how I do it and it works fine for me.
I've never measured the distance but I leave a "tiny" gap between the nock and the bottom locator (I tie them on with serving thread). I'd say, like others have noted, the gap is 1/16th-18th". I know if it isn't large enough because the arrow will be pinched and try to roll off the bow shelf or arrow rest. I don't want it any further than it needs to be or I'm defeating my purpose of helping the nock stay put throughout the shot.
