Can I Use Natural Cordage for Suspension Systems?

Selection Criteria

When choosing natural cordage for suspension systems, consider the material’s strength, elasticity, and resistance to decay. For instance, plant fibers like nettle, cattail, or milkweed are suitable options due to their high tensile strength. On the other hand, vines like willow or grape tend to be brittle and may not provide the necessary durability.

Preparation Techniques

To prepare natural cordage for suspension systems, use the reverse wrap technique. This involves wrapping the cordage around a core object (like a tree branch or a rock) in a figure-eight pattern, then reversing the direction of the wrap. For example, if you’re using nettle fibers, wrap them around a 1-inch diameter core in 3-4 layers, then reverse the direction of the wrap by 90 degrees. This process helps to create a secure and even load-bearing surface. Apply 2-3 wraps of cordage in the reverse direction to ensure stability.

Safety Considerations

When using natural cordage for suspension systems, it’s essential to test the load-bearing capacity of the material. A general rule of thumb is to test the cordage at 50-75% of its expected load. For example, if you’re planning to hang a 100-pound load, test the cordage with a 50-pound weight before adding the full load. Additionally, consider using multiple strands of cordage or incorporating steel wire as a backup for added safety.
