Quick Answer
Common mistakes in primitive bow making include selecting the wrong type of wood, poor tillering techniques, and inadequate sinew backing, which can compromise the bow's performance and durability.
Choosing the Wrong Wood Type
Selecting the right wood type is crucial for a primitive bow. Many bow makers make the mistake of using hardwoods like oak or maple, which are too hard and dense, making them difficult to work with. A better choice is a straight-grained hardwood like ash, hickory, or osage orange, which offer a good balance of strength and flexibility. Look for staves with a diameter of 1.5 to 2 inches and a length of 60 to 72 inches.
Proper Tillering Techniques
Tillering is the process of shaping the bow to its desired shape. A common mistake is to over-till the bow, which can cause it to become too thin and weak. Instead, use a tiller to gradually shape the bow, checking its shape and straightness at each stage. It’s also essential to use a tiller with a smooth, rounded edge to avoid scratching the wood. Aim for a tiller ratio of 1:12 to 1:15, which means the tiller should be 1 inch wide for every 12 to 15 inches of bow length.
Sinew Backing and Arrow Making
A well-made sinew backing is essential for a primitive bow’s stability and durability. Many bow makers make the mistake of applying too little sinew or not stretching it enough, which can cause the bow to snap or become unstable. Use a consistent, thin layer of sinew and stretch it to the correct tension to ensure a strong and stable bond. When making arrows, choose straight-grained woods like cedar or spruce and use a consistent tapering method to ensure accurate flights. Use a small notch and a consistent nocking point to ensure consistent arrow draw and release.
