Constructing the Tillering Gizmo
Step-by-Step Assembly Instructions
The construction of the Tillering Gizmo invented by Eric Krewson involves the assembly of various components in a specific order. Below are the step-by-step assembly instructions to help you build your own tillering gizmo.
| Materials Needed | Tools Required |
| Wooden Base, Metal Rod, Pulleys, Screws, Nuts | Drill, Screwdriver, Wrench |
Ensuring Accuracy and Stability
Assembly of the tillering gizmo requires precision and stability to ensure accurate results during the tillering process. It is vital to double-check all measurements and securely tighten all components to prevent any movement or inaccuracies while using the gizmo.
When constructing the tillering gizmo, make sure to pay close attention to the alignment of the pulleys, the tightness of the screws, and the stability of the base. Any deviation from the correct assembly can affect the accuracy of the tillering process and potentially lead to incorrect bow shaping.
How to Use the Tillering Gizmo
Setting Up for Your Bow
You should start by attaching the Tillering Gizmo to a sturdy surface at about chest height. Make sure the distance between the pegs is slightly longer than your bow’s overall length. This will allow for proper tension when measuring the draw weight.
Tillering Process Fundamentals
The key to the tillering process is to ensure that both limbs of the bow bend evenly. By adjusting the tension on each limb and carefully monitoring the bend using the Tillering Gizmo, you can achieve a balanced and efficient draw weight distribution.
Tips for Effective Use
- Start with lower draw weights and gradually increase to prevent damage to the bow.
- Regularly check the tiller measurements to ensure both limbs are bending evenly.
- Adjust the tension on the Tillering Gizmo carefully to avoid overstraining the bow.
Clearly understand the characteristics of your bow and how it responds to different tensions. It is crucial to use the Tillering Gizmo consistently to track the progress of the tillering process. Assume that the tiller measurements will need minor adjustments throughout the process.
Factors Affecting Tillering Outcomes
For successful tillering outcomes when using Eric Krewson’s Tillering Gizmo, it’s important to consider several factors that can influence the process. These factors can range from wood type and quality to string tension considerations. By understanding how these elements can impact tillering outcomes, you can ensure the best results for your bow-making efforts.
Wood Type and Quality
With wood type and quality playing a significant role in tillering outcomes, it’s crucial to select the right material for your bow-making project. Different types of wood have varying densities, strengths, and flexibility, which can all affect how the bow bends and performs. Using high-quality, properly seasoned wood will result in a more durable and effective bow.
String Tension Considerations
There’s no denying the importance of string tension when it comes to tillering a bow. The amount of tension applied to the bowstring can greatly impact how the bow bends and how the limbs respond. It’s necessary to find the right balance of string tension to achieve the desired tillering outcomes.
A higher string tension will result in more limb bend, while lower tension will produce less bend. Experimenting with different string tensions will help you find the optimal level for achieving the desired tiller profile for your bow.
Maintenance and Care for Your Tillering Gizmo
Routine Inspection and Upkeep
Maintenance of your tillering gizmo is crucial to ensure its longevity and accuracy. Regularly inspect all parts of the gizmo for any signs of wear, such as loose screws or cracks in the wood. Keep the strings clean and well-oiled to prevent them from drying out and breaking during use. Make sure to store your gizmo in a dry and cool place when not in use to prevent any damage.
Long-Term Storage and Preservation
With proper care, your tillering gizmo can last for many years. When storing your gizmo for an extended period, it is important to disassemble it and store each part separately to prevent warping or damage. Store the gizmo in a protective case or box to shield it from dust and moisture. Additionally, consider applying a coat of wood sealer to the gizmo before storage to maintain its quality.
Another tip for long-term storage is to periodically check on your tillering gizmo, even when not in use. This allows you to catch any issues early on and address them before they escalate. By following these simple maintenance tips, you can ensure that your tillering gizmo remains in top condition and ready for use whenever you need it.
Final Words
With these considerations in mind, you now have the knowledge and tools to successfully make and use Eric Krewson’s Tillering Gizmo. By following the steps meticulously and taking care to adjust the tensions carefully, you can ensure that your bow limbs are being tillered evenly and accurately. This simple yet effective tool will provide you with the necessary feedback to achieve a well-balanced and high-performance bow. So, gather your materials, set up your Tillering Gizmo, and start perfecting your bow-making skills today!
