Hi all, i bought a bear montana 60# bow on the internet and had it shipped over; it´s been shooting fine, but i recently noticed that when strung the top half seems to bend more then the bottom half, when pulled it seems to even out. I will post pics ASAP but i was just wondering if anyone can give me some advice on this? Thank you
Measure the distance from the string to the belly of the bow 3 inches up from fades and compare. It should be 0.125 inches more on the upper limb. That's normal. If it's much more than that or there is a visible weak spot in the limb, that's more of a concern(obviously). Posting photos of the bow at brace and full draw would help too.
Depending on how much more it's bending.
Most bows are tillered with what is called 'positive tiller'. To properly bend and balance out the top limb is slightly weaker and bends more than the bottom limb. If you measure the distance from the string to the fades, the meaurement for the upper limb should be in the neighborhood of 4-8mm more than the bottom. If it's too much more than that there may be a problem.
There are bows out there with even more positive tiller that are fine. Most of the bows with a significantly shorter lower limb are like that and can look 'funny', but the limb timing and tiller are spot on for the bow design.
Hope that helps some.
jediazul, tiller is there because we don't pull the bow from the middle....we pull it above the center. The center of the bow is where the hand seats (normally)....the pivot point. That being the case, the bottom limb needs to be stiffer to accomodate the difference.
Everyone above is right. However, Ive seen some very dissapointing things with the Montana, inclding bad tiller.
Measure the string height like arrowslinger said, and post pics. You will have your answer.
Hey guys, thanks so much for the quick response, I´m new on this but it is great to have such a group of friends and enthusiasts who share a passion for the outdoors and the treasures it holds. Will post pictures ASAP, thanks again from sunny southern Spain.
It's perfectly normal and was designed that way. If you want to see a Bear bow with even more bend than yours, look at the old Bear Polars - they almost look asymetrical when they are strung, however they shoot great. Everything on your bow is as it should be. Take care.
