This is not possible..period, 'providing the string/cable' was correctly measured at the beginning of making the string/cable. In otherwords, to make a 57" string for example you'll start off with a set of strands 57-1/8" long in the jig...it is therefore "impossible' after the string is built to end up with it being .5" (1/2") longer, unless it has been stretched to some large amount of poundage and if so the the material used is no good as any good string will not stretch that much. Usually when making strings the formula for lets say BCY 452X or Browning Xcel will be for every 100" of string you and 1/4". So a 50" string (finished) you'll add 1/8". A 25" string you'll add 1/16" and so on. The string was measured incorrectly at the beginning, not by you, but the person who built the string. Exchange the string it was built incorrectly.
Matt, have you tried to draw the bow since installing the new stuff? Does it feel different? Only reason I ask is that one time I put the cable the wrong way around and I never realized it until I tried to draw and it was quite a bit harder.
Finally had time to work on the bow again tonight. I got everything on right. I ended up taking each back off the bow, measuring under tension, and then twisting to length to re-install, but not without quirks. The string measured out of spec at 57 3/8", twisted it up to 57 1/4", and reinstalled it. Took the green control cable off. It measured at 41 3/8" (specs say 41 7/32"). Twisted that up, and reinstalled. Took, the brown cable off, and it was the same as the green, but here's the kicker. When I twisted it up to match, the material seemed extremely tightly twisted, whereas the green string wasn't nearly as taught when twisted up. I got everything back on the bow, ATA is dead on, BH is about 1/16" off (haven't synced up the cams yet, so I bet that will come into spec) but I'm a bit hesitant, so I think I'm going to try to have Bowtech replace them. Only thing is I bought these second hand (unused), so am I going to have trouble returning these? If I am, I suppose I'm out some money, but I will just replace them with some VTs, I suppose.
Just plain difficult by BowTech. They could have made the CBL 41-3/16" or 41-1/4"...but they choose to make it 41-7/32" just so we split hairs when making the string. One of the reasons I stay away from the 09' Admiral..they choose to make the STR 57-23/32"...(not 11/16" or 3/4"...but 23/32) and the CBL 35-29/32" ( not 7/8" or 15/16"...but 29/32")...do we really need measurements as exact as this, when using fibers that will stress a tad. Next we'll have to buy a CNC bowstring jig for mega bucks and then the cost of the STR and CBL will shoot past the cost of the bow...just pure complex, and un-necessary, in my opinion. MGH-PA..just in case you blow a fuse trying to get your STR & CBL to spec...I can build you a string at 'no charge' just to help a guy who's having a dufficult time with " a manufacture string". They should really do the right thing...
Yeah, I thought it out the CBL length spec is to 1/32s, and the string is 1/4. Anyways, thanks a TON for the offer for making the string (that's extremely gracious of you), but I could never let you not charge me. I appreciate the time that goes into making a set of string and cables. I'm going to try and settle this with BT...if I don't get anywhere, I might give ya a PM and discuss our options:d
Just let me know...it's not a problem, as I honestly hate learning about the brotherhood having problems and no-one trying to help. Life should be much better than that, and time really does not matter.
So my question is.... Why did you not measure them before you put them on the bow in the first place? That is protocol and the first step you do before replacing them. 9/10 times the string and or cables will need a twist or two in them out of the package to achieve proper length. I still suggest having RJ look your bow over when you guys get together. That bow has been through a lot with your tinkering.
Because I didn't think to. I'm extremely busy right now, and I'm living in two different places. I needed to replace the strings, and I only had a short amount of time to do so, so I rushed home, pulled the old strings and put the new ones on. I'm sure everyone just thinks I'm this dumb kid fumbling around with his bow breaking things doing everything wrong, but imho, it's how I'm learning. My closest proshop is run by a hillbilly I wouldn't trust with a slingshot let alone any of my archery equipment. The next closest person is Rob, and I can't just drive 40 minutes every time I have a problem with my bow, so this is the only way for me to learn. If I mess up it's MY fault. My strings being out of spec is NOT my fault. I may have forgot to measure these strings before installing them, but they sure as heck didn't gain 1/4" of length from the time I installed them to the time I took them back off. I'm betting they were off from the get go. Rough day? You bet.
Your rough day translated in a good laugh for me from reading this quote I am not suggesting that you stop tinkering, just to have RJ look it over to make sure everything is in line. RJ is an archery ninja, he has crazy skills
How about Bowtech doing some 'quality control' prior to the strings and cables leaving their location. I will repeat myself again. No string or cable, under 100" in length...none, should be longer .25" of its factory spec, fully untwisted...'providing' its correctly made. A string .5" longer, as is the case with MGH_PA string, no amount of measurement prior to installation could have gotten it to specs. Mistakes are made all the time while building strings & cables...the correct thing to do when a mistake is conceived is to correct it. That would be the appropriate thing to do, rather than pointing fingers.
Here in the USA we call that string 1/8 inch different than spec not 1/2. :d 3/8 - 2/8 = 1/8 He stated the cables were 41 3/8's instead of spec at 41 7/32's. First let's convert the eights into thirtyseconds. 3/8 converted into 32nd's is 12/32. 12/32 - 7/32 = 5/32 or otherwise known as less than a quarter inch.

[/quote] First let me apologize for saying the string was 1/2". When I first ran thru his post .5" was mentioned and I took that to be the string. Now that I have reviewed his post he was talking about his ATA/BH..my mistake for not reading his thread properly. However, you going to the pain and scarcasm to tell me how measurements are shown in increments in the USA was certainly not seen in good humor, as I am quite able to comprehend increments of an inch in 1/32". This doesn't change in any language, country, religion or race!!! I hope, with your wisdom, you can encourage and persuade your people how to build a string and cable to specs. Here in Canada our strings are built as recommended by the manuals.
No need to say sorry to me... I am a sarcastic fella' by nature... I meant no harm in my sarcasim... In fact I love Canadians, well at least the English speaking ones Forgive me if I offended
Very gracious of you...certainly feels good to know I'm not building enemies, no room in this world for that and certainly not at this time.
