    Default Vibration Reduction

    Dear Friends, Since I posted this on another thread thought I might as well share on the open forum about reducing vibration on Martin square tip limb bows. Here is a method I came upon: Another semi-secret thing I have been doing with great success is taking gel used for shoes inserts (like heel shock gel) and cutting it into almost flat wedges and putting it UNDER the limbs between the limbs and the riser. You have to start out with too heavy for your desired draw weight end result limbs. And then previously testing how far to back out the limb bolts to get at your weight. I shoot near IBO arrows, 5+ gr per lb, 312 gr total arrow weight, and 60 lb draw weight. I use 65 lb limbs on my Slayr. 1 and 3/4 turns out from bottoming out gives me 60 lbs. After measuring the limb to riser gap, then I remove the limbs (without a press) and that thickness + 1/8" make a gel insert. Then reassemble the bow and tighten down the limbs the exact amount of turns to get back to the 60 lb setting. Then check draw weight on scale again, check tiller, then laser align the bow. Then go through the rest of the sighting in and squaring process until personal perfection is achieved. Now I have a straight, limb protecting, and reduced vibration bow that shoots lights out and feels like a whole new bow. I feel the limbs have got to last longer with A. not maxed out, and B. Reduced vibration transfer to the riser account the gel interface. C. I like the idea of the load separated and spread amongst the whole tip of the limb. Seems like a win-win so far.

    Jim, you should have slapped a patent on your great idea!

    Lol, it really is basic mechanics, get perfectly aligned straight better than with human eye, make sure the limbs don't have any built in torque. Then it is up to you!

    makes sense to me. I agree, slap a patent on it asap. Much like some of the big bushings on a vehicle.

    That bow I tuned but I am trying to keep it quiet on my abilities. Have too many projects now but never had one complaint on bows I have set up. It takes 6-8 hours to get right but I am a perfectionist. If not good enough for me, it's not good enough for you.
