To measure the tiller, measure the difference in actual distance from the upper limb to the string and lower limb to the string at a 90-degree angle from the base of the limbs (the point where the limb and riser come together). Tiller adjustments are accomplished by changing the top or bottom limb weight adjustment bolt, depending on which limb is being adjusted.

- Tiller is a unit of measure. It is determined by measuring the length of the bow string and the length of the bow itself. There are a handful of other metrics available now. The first is the height of the brace. The distance between the string and the neck is indicated by this number.
How does Tiller affect arrow flight?
A lesser-known impact of inadequate tillering is that the limb tips will not finish the shot cycle together at the same time, causing the nocking point to become unstable, resulting in the arrow being deflected when it is freed from the string when it is released from the string. All of this results in a bow that is unreliable, arrows that fly poorly, and sight markings that are weak.
Why is the tiller positive?
Most significantly, positive tiller refers to a stiffer lower limb (i.e., shorter distance from pocket/fadeout to string) than negative tiller. This is done to compensate for the fact that the arrow rest is situated around 2 inches above center on most bows, resulting in the lower limb being effectively longer and hence requiring more stiffness to tiller appropriately.
What is bow brace height?
The distance between the deepest section of the grip and the bowstring is known as the brace height of a bow. When you receive your bow, you’ll adjust the brace height to the manufacturer’s suggestion, which corresponds to the range of shots that the bow is intended to make. There is a lot of trial and error required in order to discover the sweet spot where your bow shoots the finest.
What is tiller on a longbow?
In terms of bowstring to belly distance, tiller is the difference between upper and lower limb measures from the bowstring to the belly at the fadeouts. When the bow is to be fired split fingered, most bows are tillered to a positive measurement of roughly 1/8″ – 1/4″ on the upper limb. Even though I’m a 3-under shot, I tiller my bows.
What is bow tuning?
Tuning a bow entails making modifications to the arrow rest, the arrows, the cam position, and the timing of the cam. A bow can be correctly set up and in specification, yet it can also be out of tune. When the bow is out of tune, arrows will begin to fly in erratical patterns.
What is a negative Tiller?
When the tiller on the bottom limb is bigger (longer) than the tiller on the top limb, this is referred to as negative tiller.
What is an ILF bow?
Archers may interchange limbs and risers from different manufacturers using the ILF (International Limb Fit) standard. For example, a set of Stalker limbs can be used with a Dryad riser to create a new set of Stalker limbs and riser.
Should ILF limbs be loose?
Registered. For someone to have that much play is very natural. If the limb bolts are fully extended, certain risers can have as much as 1/2″ of motion in the limbs.
How do you adjust the string on a tiller for walking?
You may adjust the tiller by adjusting the top or bottom of the handle. It is a matter of perspective. When tightening at the top, you can generate a relative weakening of the bottom, if that is what you choose. It is important to note that you are attempting to regulate two factors: bow balance and limb time.
