One way to install a bowstring is to use a bow stringer tool. A bow stringer is a tool for attaching strings. The end materials are plastic, thick cloth, and some are leather, plus prusik/paracord straps. The use of this bow stringer is perfect for beginners or for attaching strings to bows that have a high draw weight. The use of a bow stringer is also recommended by the manufacturer of limbs because it is safe from the possibility of limb twists/bends or abrasions. Therefore, one of the conditions of the limbs warranty is to attach the Bowstrings with a bow stringer. Only the lack of it is a bit complicated compared to the other two methods, plus you must have the bow stringer. Bow stringers have 2 kinds of ends. One can cover the limb nock with the string completely, commonly called a pocket. The other end only sticks to the end of the limb nock, commonly called a small pocket.
Then, if you want to attach the bowstring using the push-pull method, the lower limb is stuck (not injected) on the sole. One handhold the riser, one hand pushes the upper limb while sliding the upper string knot. A right-hand push upper limb, left-hand pull handle/riser, leg hold lower limb. Right hand while pushing the upper limb as well while sliding the string to the limb nock position. Do not loosen the push to the limbs before making sure the strings are properly attached. If you are sure, then you can loosen your right hand. This method is quite difficult, especially for bows with high draw weights. You have to be extra careful if you haven’t.
In addition to the two previous methods, in my opinion, the step-through method is the riskiest to create a limb twist. Because the limb that is attached to the leg is usually not straight when pushed. I’ve been told by several people who have limb twists because of using this technique. So I don’t recommend using this technique to attach strings.
