brace height

[nhbuck1]

i have a question on brace height, if you increase it will this weaken or stiffen the shaft?

[flyguysc]

weaken

[nhbuck1]

how does it do this? isnt less brace height more powerstroke?there for more force and energy to weaken the shaft? i was just wondering if someone can explain this, thanks alot

Increasing brace height increases the draw weight of the bow, thereby increasing initial inertia and weakening the arrow. Lowering brace height lowers the initial inertia, but lengthens the bows power stroke thereby increasing overall cast and may be adjusted for stiff arrows.

so if i have i an arrow showing slightly weak i should increase brace height correct?

If your arrow with feathers is showing weak (shooting tot the right) and they are flying good/straight  then lower your BH and your arrows will shoot to left to center.

Because of the somewhat offsetting effects of increasing brace height increasing draw weight and decreasing brace height lengthening power stroke, I find it useful to experiment to see what the effect is with a particular bow and arrow.  In other words, lower the brace height and see what happens.  If you like the result, fine.  If not, move it back up.

Increase brace has always weakened the shaft for me. It is usually good to stay within the bowyers recommended brace height range.

For a weak arrow lower brace works for me. Brace height adjustment has always been a fine tuning modality for me as it only effects spine a little.

X2. We're talking seriously fine tuning here. If your shooting isn't seriously legit, and you're not very closed to tuned, it's not gonna fix your issue,

If your arrow shows slightly weak, decrease the brace height, not increase.

Depending on the exact brace height, I think changing the brace height affects most the angle of the arrow at the moment of release from the string. The closer the nock to the riser at the moment of release, the more the arrow is forced away from the rest.

That is my understanding as well.  Power stroke and other factors are a non-issue.  It's the angle of deflection and is the equivalent of fine-tuning your strike plate.  They both have the same effect but brace height adjustments are micro while strike plate adjustments are much more dramatic.
