How Effective Is Sinew Cordage for Lashing Bow Components?

April 5, 2026

Quick Answer

Sinew cordage is a reliable and effective material for lashing bow components due to its high tensile strength, elasticity, and durability.

Making Sinew Cordage for Bow Lashing

To create sinew cordage, start by processing rawhide strips into thin, flexible fibers. Cut the rawhide into 1/8-inch wide strips, and then soak them in water for at least 24 hours to soften. After soaking, stretch and pull the strips apart to separate the individual fibers, which can then be cut into smaller pieces.

Preparing the Sinew for Lashing

Once you have prepared the sinew fibers, you can begin to create the cordage. To do this, twist the fibers together in a figure-eight pattern, applying gentle tension to prevent tangles. Aim for a cordage diameter of around 1/16 inch (1.5 mm), which is ideal for bow lashing. The twisted sinew can then be wound onto a stick or dowel to form a compact coil.

Lashing Bow Components with Sinew Cordage

When lashing bow components, use the sinew cordage to secure the limbs, riser, and other parts together. Apply a thin layer of rawhide glue or beeswax to the lashing points to enhance the bond. Use a minimum of three wraps at each lashing point, and space the wraps evenly to prevent uneven stress on the bow. The sinew cordage should be tightened firmly but not overly taut, allowing for a slight give when the bow is drawn. This will help to prevent the bow from cracking or breaking under tension.
