View Full Version : little string tuning problem with 07 synergy
01-29-2008, 03:24 PM
i got new strings for my 07 synergy 60#. Brace height is on, ATA is 1/16" short, but it always was for me.
Right now, I have the cables hitting the cam (they are either barley touching, or not touching... its hard to tell) i adjusted the draw stop peg to get this. Now, seems pretty good. im shooting 60.5 pounds. my letoff weight is close to, if not 12 pounds, which should be 80% i think. its hard to tell holding the bow down and reading the screen on my scale, lol.
but i have an extremely small ammount of valley.
and also when looking at the cams, im sure this isnt good, the bottom cam seems 'under rotated'. (the top cam has rolled over more then the bottom cam) but only about 1/8" at the most.
to get more valley, i know i can move the draw step peg a little towards a lower number. but then,,, would i have to untwist the cables and then, i would loose poundage right?
thanks in advance for the help.

I get so confused on Binaries. brace height 7 mine hits more 7 1/8th A-A 33 1/4 mine more or less hits that. what i usualy do is max out the limbs. pull the bow down on the scale and see what i get. (you gotta trust and know your scale is on). if it comes in low say 58lbs. then i know the string streched if the cam stops are still good. most of the time i have to adjust string and cables to get the max pounds. if i twist the string to shorten A-A it adds to the BH. then i usualy have to do a 1/2 twist out on the cables. I have found it to be easier concentrateing on max pounds and Cam timing to get the A-A andBH close. (1/16-1/8). the string should almost be coming off the cams straight down the grove towards the other cam.
I don't think i'm good enough to put exactly how i do it to paper.LOL
not a tech by any means but this has worked for me. 07 Synergy 50-60 lb

I'm a novice with the Elite bows, however a Binary is a binary.
The cams on my Synergy are almost (if not) exactly in the same position. By design, they can't be out of sync. If the mod stops are hitting the cables at the same time. It's all in the eye.
When tuning mine , I was told to pay more attention to weight and draw length. my ATA is 1/8 short and brace is 7 1/4". At this position I have 71lbs and the mod stops are slightly contacting the cables at full draw. If I were to set it so they are 1/16" off the cavles I would not have valley either.
My draw stop peg is +.2 (6.0 now as opposed to 5.8 according to spec's). This will remove some of the valley but it's necessary to keep the mod stops in the correct position. Set your stops to just "kiss" the cables.
I would check draw length first. I think that's where I would start. Your weight is good, but a twist on each cable wouldn't hurt.
The only other way to check your set up is to take your cables and string off and measure them. Put them at proper length and re install. I was told this by Dave Nowlin. If you PM him he can give you specific details on this method.

good post archer. i played with it some today before reading that. whats weird is i was shooting 302 consitantly the other day, i shot it again before tuning, and i was shoting 299 :noidea:ut i played and played and played. and i prety much decided to do what you recommended. but i put a few extra twists in the stirng, and it went from 61 to 63# shooting 303 consistantly. (i wonder if its bad to have 63# on a 60# bow... birth Certificate said it was 61.5#)
but, im gonna go shoot some, see what its like. then maybe tune on it later.
i think it should be a more well know fact that one some bows like ours apperantly you have to have the cables hitting the stops just a little. i have never read that before. but decided that was the only way i would be able to hold my bow without it wanting to rip my arm off if i let down just a hair :bricks:
