I have a Hoyt Alphamax 32 with 60 lb. limbs. Only problem is, it only pulls 55 lbs.with the limbs maxed out. My other 60 lb. bow pulls 63-64 lbs. Why cant I get that out of my AM? I know you can twist strings and or cables to get more poundage, can anyone give me some guidance on how to do that? Thanks for any help you can give me.
Your bow is out of tune, way out of tune. I would take it too a pro shop and have them re tune and re spec. also, paper tune.
Tuning will not increase the DW to 60. When you get the bow to the pro shop have them check the axle to axle and brace height to see if they are in spec. If they are not then the shop should know how to get them set correctly. Once the bow is in spec have them check the DW then.
Check the specs like Bruce said another thing to consider is if the strings are old and stretched out that could be a problem too.
In what way? If a bow is out of tune (i.e. cam is over and under rotated) it will not pull it's peak weight. either over or under. The bow must be re-spec'd ( ATA and Brace Height Set) then paper tuned because it will surely shoot different now.
Thanks Thanks guys for the help. Sounds like I'm gonna have to take it to a shop. I was trying to avoid that because its pretty far from where I live, and expensive. I appreciate the input.
Perhaps we just have a terminology difference. I would call that timing the cam(s) and that is part of getting the bow in spec. After the bow is in spec then the tuning begins. Kind of like installing a new string, you get in spec, to include cam timing, and then you set the bow up and tune it with the arrow.
You don't need to take it to a bow shop but you do need a press and some knowledge, along with a methodical approach to experimentation for twisting strings and cables and their effects on your bow. This is a good resource, it's by Elite for their bows but the rules apply to all bows (just ignore the draw stop info and the warnings at the bottom unless you have an Elite or other 2 track binary cam). http://www.elitearchery.com/technology/pdf/cam_adjustment_basics.pdf It may take a bit to think through it for single cams and cam 1/2 rigs but the same principals still apply, it's just that you've only got one cable and one string to deal with. Get the spec sheet on your bow at the manufacturer's web site and work toward getting the ATA and Brace height where they belong, then check the cam rotation to see if it's where it belongs. Lastly check the poundage to see where it is. It should be +/- 2 lbs. of the stated max. Hoyts usually come in right on the money. Be sure to make all these adjustments and measurements at full poundage (limbs bottomed out)! An important thing is to either write down or remember exactly what you did in each step so you can put things back if you go the wrong way. Whatever you do to one cable you should do to the other, assuming they are in balance. Go in small increments (usually no more than 3 twists at a time). 5 lbs. is a lot to lose but some of the older Hoyt / Fuse strings were known for being creepy. It may take 5-10 twists to gain that back.
NP Donnie. Those guys at Elite did us a great service putting that out. I wish I had it 15 years ago when i started playing with this stuff. Instead I learned by trial and lots of error!
