Just bought a new heli-m. absolutely love the bow. 50-60 lbs. I'm trying to crank it up and keep it just below 60 lbs. However it is getting very hard to turn the allen screw on the limbs. One allen in particular seems harder to turn. I don't believe they are maxed out though unless my scale is off. I guess my real concern is that the limbs aren't even in terms of how tight they are (one is cranked up more than the other). Is this a problem? And how do I even check this? I want everything to be perfectly tuned on this thing.
Yes. Do not shoot it like that. They should both be cranked equally. You need to tighten both of them as far as they'll go (max draw weight). Then back each one off one turn at a time, doing the top, then bottom, then top and so on until you reach your desired draw weight. Just as a reference, on my Bear bow, one full crank on both limbs equals approximately 2-4lbs of draw weight change. I just figure it's 3lbs for one full crank. Your heli-m may be different.
If I keep tightening them, will they eventually both bottom out? I would have to think so but I don't want to damage anything by cranking them too much until they bottom out...
If it was already uneven like that to begin with, I'd run it back to the shop you bought it from and have them look at/fix it. If you didn't get it at a shop, can still take it to one and they more than likely won't charge just to check it out and adjust the poundage.
You can bottom them out, just don't over crank once they're bottomed out. This isn't a helium I don't think but a similar mathew's bow: That's bottomed out. Do your limbs look like that? Also good advice ^
Take the bow to an archery pro shop that specifically handles Matthews. And don't shoot it in its current condition.
One way to check and see if they are equal is measure the tiller. Go to the bottom of the limb pocket and measure to the string go to the bottom cam and measure from the same point. ( that's a must) if the measurement is within an 1/8 of an inch your good
