How to tie in nocksets and a D-loop
I found this on another forum but figured I'd pull it over here. Pretty good thread.

I finally decided to document the process of how I tie in nocksets and my D-loop as I set up another of my bows. I offer a quick disclaimer: This is not THE way to set up your nocksets and loop; there are at least six different documented ways to tie in a loop and where to place your nocksets. Noted archery expert Larry Wise wrote recently, though, that he's seen approximately of tournament archers use either the method I'm going to demonstrate below, or he's seen archers just use one nockset below the nock. Although at first glance you would think that having equal-length nocksets above and below the nock would yield the most-uniform pull (or the absence of any nocksets and just using the D-loop's knots), having a longer knot length below the knot allows the release to pull directly behind the arrow nock -- as you'll see at the end.

First things first, though... I affix my bow in my vise and snap a level on to make sure it's not leaning or canted any way. I want it to be exactly plumb and square as I'll soon be locating where my first nockset needs to go.

Next, I gather my materials: Some BCY nock point tying thread, and some waxed dental floss.

Cut off about ten inches of dental floss, as well as about a foot of nock-tying thread; it's way more thread than you'll use for the actual knot, but this stuff is extremely cheap -- and you'll appreciate the long tag ends which you'll be able to grab as we tighten the nock set later on.

The first thing we want to do is to take our looped dental floss and lay it alongside your bow string's center serving. Then, take your nock thread and lay it alongside the floss, leaving at least six inches above your hand as a tag end.

You'll see in the next pic below that I've wrapped the knot tying thread back on top of itself three times. Notice that I made my first wrap at the bottom, and then started working the wraps UP towards the top. One more wrap, and this one is nearly completed; my top nockset consists of four wraps.

After completing the last wrap, I stick the tag end with which I've been wrapping with through the loop created by the dental floss and pull that end back under the wraps.

Once pulled all the way through, your first nockset should look like this:

You can snug it up against the center serving to keep it from slipping down, but be cautious to not tighten it too much at this point; we need to locate exactly where we want it first. The beautiful thing about this is you can slide this nockset up and down until you get it exactly where you want it before tightening it down.

For my BowTechs, I've discovered that a good starting point is to set them up so that the arrow is perfectly level and square to the bowstring. In this pic, you'll see where I've unhooked the turnbuckle sleeve off my Muzzy Zero Effect so that I can position the arrow in its raised state. Ensuring that the arrow shaft passes squarely through the berger holes, I adjust the location of where the nock snaps onto the serving until my level bubble is perfectly centered between the lines.

Slide the nockset to where it makes firm contact with the arrow nock, ensuring you don't move the arrow in the process. Remove the arrow and grab both tag ends and pull hard, cinching down the nockset to stay. This is where you'll appreciate the extra-long tag ends; I usually have enough to wrap over my hands and can pull on them as hard as I can.

Snip the tag ends off with a sharp knife or razor, leaving about an 1/8 of an inch. I take my bow out of the vise so I can lay it down horizontally on my work bench, and then light the tag ends with a lighter. Watch them burn carefully, and just as they reach the nockset, simultaneously extinguish the mini-fire and push them up into body of the nockset.

Here's my top nockset in place and completed, and my bottom one has just been slid into place and is ready to be tightened. Note here that I've wrapped my bottom nockset EIGHT times as opposed to the four used to complete the top; I've found this combination will allow my release to pull directly behind my arrow nock, as you'll see in the last pic.

Key takeaways to make this process quick and easy: Don't be stingy with your nock-tying thread; the stuff is extremely cheap, comes on 75-yard rolls, and the more you use the easier it is to grab the tag ends and pull after you make your knot. Also, remember when wrapping around the serving and the dental floss to wrap UP and back onto the knot tying thread itself -- that way, when you insert the tag end into the dental floss, you'll actually pull that tag under its own wrappings, which is what makes this knot so neat and precise.
