Brace Height Adjustment??

[eddings220]

Hey everyone, I am a novice at tuning a traditional bow,I have a new TallTines ordered from Brian so I am trying to learn as much as I can about tuning.  I have an old PSE recurve now, so I have one to play with. So I have a few "novice" questions:

1. Proper/Improper brace height setting affects what in the shooting of an arrow?
2. I think I understand that twisting the string adjusts brace height, which end of string should be twisted, or does it matter?

Hi Mark,        
1. Improper brace height can make a bow louder than normal when it's shot.
Mainly, it effects the dynamic spine of your arrow (how weak or stiff the arrow acts as it's being shot).
By adjusting brace height lower, or higher you can use it to tune your arrows for optimal flight. (Just make sure you stay as close to  your bowyer's recommended bh for that particular bow).

2. When you do twist the string... you want to be careful not to UNtwist it very much, because this is how a flemish string is held together.
You don't really have to watch it as closely if you are going to put more twists in a string.
Ah, you ask, how do I do this...
With the bow unstrung and the upper string loop still on the bow limb, but not in the string grooves, you simply take the bottom loop off of the bottom limb tip and you will want to twist the string in a Counter Clockwise direction. Usually about two full twists will raise you bh up about a quarter of an inch, but this varies.
Here is alot of good tuning info for you-

Also, the masters of the barebow 1,2,&3 dvd series are a great way to see how to tune a bow.
If you have any more questions, feel free to private message me.
hope this helps,

ps. forgot to mention that anytime you change your bh, you need to recheck and re-adjust your nock height because this will have changed.

Heh Bud,
Welcome to the best website on the planet !

Every bow / bowyer has a recommended range for brace height. Some are around 7-7 1/2" other likes older Bear recurves can be as high as 8-8 1/2". measure from the string to the deepest part of the grip. You change by twisting the string clockwise or CCW. Unstring the bow and take the string off the bottom limb, then looking up toward the top limb along the back of the bow, ( the side closest to you ), twisting CCW will increase the brace height. You could reverse this process and do it from the top limb, does not matter.

As far as the sweet spot, that will be determined by each bow and shooter. As you raise / lower it and shoot you will know when you are close. When it is right the bow will shoot smooth and quiet with less vibration or handshock. I am not sure about your PSE's recommended brace height, maybe you could get it off the PSE website or other PSE shooters can tell you ? Make sure you check your brace before shooting and tune before each session. Once you get a set of arrows flying good out of it you must maintain that brace height to keep everything in tune. It all goes hand in hand. When you get a chance read up on old threads here about bareshaft tuning your arrows too.
