BCS string/cable change - WARNING
WARNING
Anyone twisting cables or strings on the Binary Cam System should be VERY careful. Doing so can change let-off drastically to the point where you'll get the bow LOCKING at full draw. It would be the same as if you removed the draw stop, which is a NO NO, and documented by a tag on the bow and in the Owner's Manual.
If it would happen to you, DON'T PANIC. You would need help to get the bow to let down. It happened to my bow Tech and luckily he knew better than to let off the string. It was easy for us to get it down because we moved it to a tool that I designed. We let it down easily with the tool. Most wouldn't have that luxury.
If this were to happen to you and you would panic, letting go of the string could result in a dry fire. Dry fires can damage the bow, but moreso could hurt you. This would never happen unless you removed the draw stop or changed the cables/string length.
PREVENTIVE ACTION: If you do change string or cables, a way to prevent 'lock up' from happening would be to move the draw stop to a much lower let-off. You could then move the draw stop up to a higher let-off once you checked the amount of let-off on a bow scale.
This is not meant to scare anyone. The BCS is a very safe and great new cam system. Like with many mechanical products in the world, there are warnings issued about doing certain things that could cause adverse situations. Think about how many warning labels are on products we buy every day.

RE: BCS string/cable change - WARNING
We should try to keep this post at the top of the order for a few days--it ain't a good feeling damaging a new bow., or more so injuring yourself.
Hey Len--know ya got to feed the family--how about feeding me some info too and tell me what that majic tool is.
I will have my apple press on standby if the BCS locks up at full draw, but a portable will certainly be helpful.
Time to get WWAG in here.

RE: BCS string/cable change - WARNING
Len, I may already know the answer to this, but since you're the guy I look to for these sort of answers I'll ask.
How many twist does it take to really mess something up? The only reason I"m asking is that I put one twist in my string the other day to get my peep to line up. I read through my manual carefully and this is what they recommended.
On another note, I have been shooting my Allegiance for about a week now and everything seems to have settled in nicely. The strings and harnesses seemed to have stretched a very very small amount, but I attribute that to settling more than actual stretch. What I noticed is, that my timing marks on the top and bottom cam have moved exactly the same amount since I got the bow. Looks like this hoopla of equaling each other is holding true for these bows.

I made this post for the purpose of informing Dealers as well as others. It is a new system and, unlike most other systems, has this problem.
It happened to us when changing cams from one bow to the other. My Tech had forgotten that he had put some twist in one bow. Evidently the tolerances were enough to cause this to happen. It can be prevented as I mentioned.
The Owner's Manual covers this topic; but, how many don't read the Owner's Manual. I'm very guilty on this subject.
Very rare as this occurrence may be, bringing attention to it may help a fellow archer.

Of course we are all still waiting for "that" guy who just has to see for himself to post........"Hey, I took my draw stop peg out on my new Allegiance and I have a bit of a problem"[:-]
Not to mention he'll have typed it with his toes because he's scared to death to let go of the string.

Umm, This has already happened... Just so happens it was the very day we put the Equalizer Binary Cam System link on the home page. The person read the information and decided to see what would happen if they removed the stop...It locked up at 100% let off just like it said would happen...Imagine that...

RE: BCS string/cable change - WARNING
Just out of curiousity, exactly how do the cams lockup at full draw? How is this possible on the Equalizer cam system and not on a typical dual, single or hybrid cam? I have only recently gotten my hands on some Equalizer cam bows and have not yet had the time to begin tinkering with them.
Thank you ahead of time.
