at the moment i have my bow strung up. It's 64" long with 60" string and the brace height is just over 6 inches. Was just wondering what a good Brace height to start with would be before i start playing around with it to find the "sweet spot". Should i start at 7" and work my way up? what brace height do most people have their's set around?

Every bow, arrow, and form combination is different, even a little for different shooters. I usually start between 7 and 8 and first go down an inch or so then past start then up an inch or so. I sometimes have to do this a couple times to find the right spot.

it helps to know what kind of bow you have. bowyers have different recomendations for brace height parameters based on their individual bows. that being said, i would think 7 1/2" would be a safe starting point and tune from there.

For the most part bows shoot the best at the lower range of the brace height range. If you let us know who made it or what type of longbow it is I'm sure someone could narrow this down for you.

I have two 66" Blacktail TD recurves. Sometimes I feel like experimenting with them. The recommended brace height for them is 7 3/4"-8". With my 30" draw length and since I'm shooting heavy stiff aluminum arrows with 165 grain point weights out of both of them, I found these bows like a longer power stroke.
The sweet spot for each of them is the same, but not what is recommended by the bowyer. For my 42# bow, shooting a 32", Easton Camo Hunter 2117 arrow, the brace height (sweet spot) is 7 3/8" and for the 37# bow shooting a 32", Easton Camo Hunter 2114 arrow, the brace height (sweet spot) is 7 3/8" also.
Sometimes one has to think outside the box and not go with what is recommended. Do a little experimentation and you may be pleasantly surprised.

I've found by starting with very low B.H., I definetly know I'm at one of the limits, just because it's LOUD. From that point, I begin to increase B.H. until things quiet down. If I start out too high with B.H. I don't have that same degree of "auditory definition"

I shoot a Fox High Sierra TD recurve 64" 59 @ 30'.
Is there a knack to twisting the string and restringing the bow when brace height tuning? As i am yet to try increasing the brace height on my bow. From memory i think i was told to turn the lower part of the string counter clockwise to increase brace? is this right? Matt

Depends on how the string was twisted, Matt. Just look at the windings to answer your question on direction.
I like to start at max brace height with a slightly stiff arrow, then shrink the brace height as I fine tune. I would rather gain speed than lose it while fine tuning (slightly soft arrow).
Min brace height = max speed and easiest initial pull/less forgiving.
Max brace height = Less speed, harder initial pull/more forgiving.
Sweet spot is in there somewhere. Always check nock height.

the bow will tell you when ya get there. I just started playing with BH and don't know how I tuned with out it. When you get in the right spot the bow will get whisper quiet, smooth and forgiving.

You adjust brace height be lengthening or shortening the string. If you twist the string and make it shorter, in effect, when you restring the bow, you pull the two limbs closer and move the string further out from the bow, thus increasing the brace height. Lengthening the string by untwisting will shorten the brace height.
The shorter the brace height, the longer your arrow is in contact with the string during release. This results in a longer "power stroke" and more speed. The increase in speed is likely not that great, maybe a few feet per second, though I have never actually measured this.
You can get a pretty good idea of what brace height your set-up likes fairly quickly by setting your brace height at about 7.5 inches. Shoot several arrows, making a mental note of noise and arrow flight. Then reset your brace height to about 7.75 inches. Shoot several arrows. Is it quieter and do your arrows fly any better? Set your brace height to 8 inches. Shoot several arrows. How does your bow sound, and how are your arrows flying? You are looking for the best arrow flight with the least amount of noise.
Noise and arrow flight will ultimately decide the best brace height for your set-up.
Once you find out roughly what range of brace height seems to work best, you can fine tune your set-up by making 1/8-inch changes in brace height over a smaller range. Make sure that you are comfortable you have good shooting form, because your ideal brace height may be something of a moving target until you have good form. My longbows tend like about a 7-inch brace height. I have several recurves. They tend to shoot best at brace heights ranging from just under 8 inches to about 8.5 inches.
Good luck!
