Quick Answer
Older bark is generally more suitable for cordage due to its increased density and reduced moisture content, making it easier to strip, process, and dry.
Bark Harvesting Technique
When selecting bark for cordage, it’s essential to choose sections with a minimum of 5-10 years of growth. Younger bark tends to be too brittle and prone to breaking, while older bark provides a better balance of strength and flexibility. Opt for regions with minimal damage or disease, as these can weaken the bark and compromise its durability.
Processing and Preparation
To prepare bark for cordage, start by stripping it from the tree using a knife or sharp rock, being careful to avoid damaging the inner layers. Remove any loose or damaged fibers, and then soak the bark in water for several hours to soften it. Use a mallet or pounding stone to break down the fibers, and then rinse and dry the bark thoroughly. It’s recommended to dry the bark to a moisture content of 10-20% to prevent mold and mildew.
Cordage Production
Begin cordage production by separating the bark into individual fibers, using a combination of pulling and cutting to release the fibers from each other. Twist the fibers together to create the cord, using a consistent twist rate to achieve the desired strength and flexibility. Aim for a twist rate of 5-10 twists per inch to create a durable and long-lasting cord.
