Quick Answer
In high humidity, your bow drill components will likely become brittle and prone to cracking, especially the string and drill. This is due to the reduced moisture absorption of the wood and the increased dryness of the cordage. As a result, your bow drill may not function properly.
Effects on Wood Components
High humidity affects wood components by causing them to become excessively soft and pliable. This can lead to a loss of drill shape and potentially cause it to break during use. However, if you have a well-seasoned hardwood drill, it is less likely to suffer from damage due to high humidity. It’s essential to use a drill made from a hardwood, such as hickory or ash, which is more resistant to moisture.
Effects on Cordage
Cordage, specifically the bow drill string, is more susceptible to damage in high humidity environments. When the string becomes brittle, it can easily snap when stretched, rendering your bow drill ineffective. To minimize this risk, choose a cordage with a natural waxy coating, such as plant fiber or wax-coated cordage, which provides better durability in humid conditions.
Preparing for High Humidity Environments
To prepare for high humidity environments, consider using a bow drill with components made from water-resistant materials, such as bamboo or a waterproof cordage. You can also use a bow drill with a shorter drill and a stiffer string to minimize the impact of high humidity on the components. Additionally, store your bow drill in a dry environment to prevent long-term damage.
