brass knocks
 
What do you guys use to loosen these? I tried a little screw driver but i can't getter to open up.

I've used a knife blade slid in the crack and prying them apart. A screwdriver to do the same thing. The best thing I've found is to not use them in the first place. It took me 30 years to discover that all they did was slow the bow down. Now I tie mine on. One of the good things about a tied-on nockset is that it can be screwewd up or down the string just like a nut on a bolt. And once adjusted it just doesn't move. The other side effect is that each brass nockset robs a bow of approx. 4fps.

They make a tool for it. It looks a bit like needle nose pliers and is used for installing and removing nocks. Unwaxed dental floss and a little glue makes a great nock. Like BG Fisher said it is easy to adjust. GGBH

GGBH, I used to use dental floss, but recent years has me using regular braided serving material to tie on the nockset. I get it close to where I want it, wrap it around the serving and tie a granny-knot. Wrap around the other side of the string and tie another one. Back and forth about 6 times with the knots about 180 degrees apart. The last knot is a square knot and then I use a lighter to melt the ends, tap out the flame and no glue needed.

Tied on nocks move easily by twisting them around the string. One way goes up, the other end comes down, think of the wraps of the serving as threads on a screw.

For material, any serving material will work fine.

To tie the knots, its the same as when you start tieing your shoes, cross the ends over, then one around and through, and pull. Just do it the same every time, I always put right over left and then pull the now right hand one through. Then do the same to the other side of the string. On the last one end with a square knot, which is really just two of the knots you just did, sort of like tieing your shoes in a knot without the bows.

I also use these tied in knots to tie my peep in while tuning. The knot can be slid up/down the string, one above and one below the peep, this way if I need to move my peep I can. Once everything it perfect, I serve the peep in.

Stay away from the monofilament serving.

Qt to tie q square knot--Imagine the left end of your string is red. pass the red end over the right end and bring it up thru the loop, now the red end is on the right, pass it over the left end and up thru the loop. Thats a square knot. notice that on both sides, that the knot has two parallel strands. GGBH

QT, it sure does. Most common sizes are .018, .021, .025, and .026. You can see them at one of the websites for Brownell or BCY. It doesn't really matter which you use for a tied in nock. What they are for is to get the right nock fit for your center serving which can vary due to string amterial and/or which string material your string is made of.

A generic term for them is braided fastflight.

i use my nocking pliers to pry them apart. it isn't easy to describe how I do it, but it works. I prefer a string loop now though.

This is THE tool to get.
It will crimp both sizes of brass nock-sets, and remove them too.
The lever on the side is for removal.

Trufire crimpers

RE: brass knocks
 
Bulzeye, yeh, these pliers work very well. And do you see that little lever sticking out to the side? There is a little tit sticking out in the middle that you place in the split of the nockset, cam over the little lever, and it's splits the brass nockset open for you. You'd have to see it to see what I'm saying but I use them at the shop all the time.
Of course, if you quit using brass nocksets then you don't need the pliers, unless you are working on other bows.

RE: brass knocks
 

and whats a square not?
I know others have posted, here is just another way to remember:


With the ends in both hands....

Right over the left and under.....left over the right and under....pull

The same string does all of the looping.
