View Full Version : MOAB Poundage not right and flat string

08-25-2009, 02:04 AM
I recently purchased a new 09 Moab 45-60lb.
It is set at 29" draw.
I noticed the idler lean and twisted the yolk string a couple of times to straighten. No Problems.
I had the bow set on 50lb. I went to increase it and discovered i only had 1 turn on each limb left until full poundage (about 53lb)
Where is the other 7lbs?
I also note that the string in the idler wheel looks flat not round?
any advice?

Cable needs twisted some. Check the length from axle to axle.

thanks, i put a few twists in and gave it some wax as well. That got rid of the flat spot on the string. Any ideas where my poundage is? the limbs have 2m 13 1/09 on the top limb and 2m 13 12/08 on the bottom, written on the inside that you see when you loosen the bolts off to get to the cable/cam etc.

put 5 full twist in the cable. that should be just about the 7 pounds your looking for.

Check the A2A, to make sure they have the right amount of preload, if this checks out you have the wrong limbs for 60# all my 60# Martins have had 3M limbs, but they were not MOAB's.

Thanks all, If i put a few more twists in the string, this will make the BH greater? and the ATA shorter? Or would the chnage not be that noticeable?

The ATA is just shy of 32.5", Brace Hieght are even at aroud 8"
Is there a list of what the limbs mean? Ie: 2M 3L etc? Surely Martin would not have put the wrong limbs on?

thanks again

it would not be the first time that the limbs did not match the sticker on the bow, yes i have seen it before, more then once.

Sumpin ain't right. Brace height should be closer to 7-7 1/8". A2A sounds close.

08-26-2009, 04:00 AM
OK, thanks again guys, I got the brace height right (Was measuring wrong)
I'll take the string off again and put a few more twists in. I straightend the string and then added about 12 twists earlier today. Poundage is 53. So i am back were i started. I'll put a few more in later( 5 or 6).
Then check brace height and poundage again.
Hopefully with positive results :-)

hmmm.. twisted string up about 6 turns more, still 53lb.
Twisted up another 6, brace height is 180mm(just over 7").

My nocking point has moved up nearly half inch.

The string last time i twisted it, started twisting over it'self. I have also noticed the top limb is getting harder to wind in compered to the bottom limb(may have always been the case but i am getting sore hands for winding in/out repeatedly )
All this effort and i have not gained any poundage?
So i dont know if it is safe to keep twisting the string or if indeed i have the wrong limbs. ??
Anyone from Martin able to reply?

do yourself a favor & call Martin Archery... to make sure you have the right limbs. Sorry, but I can't help you on this issue.

Good Luck,

you said you twisted the string?

twist the buss cable. not the string. every 6 twist in the string shortens the DL and does not change poundage.

put 5 twist in the buss cable and take the twist that you put in the string back out.

Michael is right. Twisting the string reduces the draw length while reducing the weight. But being as the string is so long it takes quite a few twists to see much change on draw weight. The cable, being about half the length of the string reacts to changes more quickly.

Know what I'd do? I'd take about 6 twists out of the string and add 6 to the cable and see how this works.

I guess I didn't tell you, but before you even started you should have drawn a pencil mark on the side of the cam where it passes through the limb fork. This would have given you a reference for draw length.

Ok. Taken a few twists out of the actual string, put a few twist in the small cable to the solo cam.
It appears i have gained about 2 lbs.....
I'll repeat the following step later and see if i gain another couple of lbs.
The A2A is just a bit over 32 and a quarter, Brace height a little over 7".
Might be on the right track now...thanks again all, i'll keep you posted.
Oh..BFisher, i did mark it with a white marker and have been seeing the mark change location. I it still a shy short of where i started. But after next adjustment should be back on that mark again. :-)

I have noticed that both limbs have MARTIN written on it. Yet photos i have seen of the 09 MOABs Have MOAB on one of the limbs...
I sent an email off to Martin asking for clarification.
Failing that, i will have to wait up one night to ring them (15+ hour time dif)

08-27-2009, 11:32 AM
Yow!!!!!! 15 hours? Where you located?

08-27-2009, 05:47 PM
Im an Aussie :-) Actually 17 hours difference. 11am here and it's 6pm yesterday there. So your reading into the future..lol

Martin got back to me, we are arranging to get another set of limbs sent out as they should be marked with a 3 not a 2. :-)
so case closed?
Thanks everyone for your assistance

Can i say I told you so, like i said I've had a lot of Martin bows with 60# limbs and all of them with short A2A had 3M limbs.

OK old man. You don't have to rub it in.

Hey Aussie, glad to see Martin is taking care of you. Now maybe you can quit twisting things out of whack and get 'er tuned and enjoy.

You can say that :)
