Tiller question

[[email protected]]

My first and favorite bow, 45lb Predator Hunter, has a 1/2" difference. Top is longer. I've noticed it over last couple years. There's no adjustments like an ILF bow so what do I do if anything? Should I be concerned. It's an older bow 10-15+yrs

While I’m no expert on Predator bows, the ones I have seen have an adjustable tiller, even though they are not ILF.  Do you think it's possible that your bow has an adjustable tiller, as evidenced by some Allen screws near where the limbs join with the riser beyond those needed to fasten the limbs to the riser?  If so, you could adjust the tiller to a more normal position, like 3/16” positive rather than 1/2” positive.

If the tiller is not adjustable, and Predator made the bow with a 1/2” positive tiller, I’m sure they had their reasons for doing that, and you shouldn't worry about it.

If Predator did not make the bow with a 1/2” tiller and it is not adjustable, and it just moved into that position over time, it could indicate some inherent weakness in the upper limb.  Check it from time to time, and if it continues to increase, it could indicate that this bow has outlived its usefulness and should be retired.  You're not going to be very proficient shooting a bow with unbalanced limbs.

It's entirely possible that the bow was set up to shoot a fixed crawl with that much positive tiller. using an elevated rest with a lower finger placement would help balance out the limbs.

My question is how well does it shoot for you?  Sometimes a tiller measurement can be off quite a bit and still shoot excellent. If the limbs are bending in slightly different locations from the riser fades, the limbs will balance out with different tiller measurements.
