Bruce,

I am not much of an expert, but I recently switched to 3 under as well. I was shooting a recurve and made no changes at all. Nock point, arrow, anchor, they were all the same. I have noticed a slightly tighter group, so I am happy with the switch. I just got a longbow and have only shot it 3 under with no problem. Hope it helps.

While I think it’s nice that custom bowyers offer the option of tillering for three-under, it’s kind of a moot point. Back when archery was archery, Bear, Pearson and the likes turned out tens (if not hundreds) or thousands of bows per year. They weren’t custom tillered, and folks shot them just fine. As for myself, I’ve never had a problem shooting three-under with any recurve regardless of whether or not it was tillered specifically for it.

I was wondering what difference it makes to my bow when shooting? I have not noticed a difference in arrow flight. I have noticed a little bit more bow noise and also that there seems to be a little more arrow contact with the outer edge of my bow shelf. The bow is a custom recurve, and was built to accomodate split finger shooting.

Any comments greatly appreciated . Bruce

The reason your Bow is noisy? When you change your grasp on the string by going from split to three under, you have changed the dynamic balance and timing of the limbs. With Bows tillered for split finger shooting, the Bowyer has timed the limbs to make up for the higher finger placement on the string. The top limb usually is tillered “Positive” by being a little weaker to compensate for the split draw upon the string. Most three under shooters require or prefer a Bow tillered to “Zero tiller” to balance up the limbs for the more even (closer to the center of the limbs balance point via the string)dynamic timing of the limbs as the arrow is shot. The noise your getting is from the inbalance your getting from a postive tillered Bow. I have always been able to tune a positive tillered Bow to be quiet and perform as normal by shooting a bare shaft per tuning for tens (google search) and adjusting the nocking point upward to put a little more pressure on the top limb. There is a downside to this! By moving your nock point up, you cause the arrow to shoot lower than normal in some set-ups,,,which moves your point of impact your used to. If it is “Pet Bow”??? just tune it and get used to the new POA,, if not,, have one made tillered even.:)
