Preparing a Live Tree for Turning on a Lathe: A Comprehensive Guide
Preparing a live tree for turning on a lathe involves several important steps to ensure the wood is suitable for your project and to minimize issues like cracking and warping. This comprehensive guide will walk you through the entire process, from selecting the appropriate tree to final preparation and turning techniques.
1. Selecting the Right Tree
The first step in preparing a live tree for turning on a lathe is selecting the right tree and ensuring it is in good condition. Here are the key considerations:
Species Selection
Choose a species known for good turning properties such as maple, cherry, or walnut. These species are known for their stability and workability.
Tree Condition
Look for a healthy tree with minimal defects. Avoid knots, rotten sections, or any signs of disease. A tree with fewer defects will yield better results during the turning process.
2. Felling the Tree
Safety First: Before felling the tree, ensure you have appropriate safety gear. Use gloves, a helmet, and eye protection to protect yourself from any accidents.
Cutting Technique: Use a chainsaw to fell the tree. Follow proper felling techniques to minimize damage and ensure a safe and clean cut. This will also help in obtaining uniformly sized sections that are easier to handle and work with.
3. Limiting Damage
Avoiding Splits: Cut the tree into sections as soon as possible to prevent cracking. Ideally, sections should be no longer than 2-3 feet to ensure uniformity and ease of handling.
End Sealing: Apply a wood sealer such as wax or PVA glue to the ends of the cut logs. This reduces moisture loss and prevents checking, which is the appearance of small cracks or splits in wood due to drying.
4. Bark Removal
Removing Bark: Strip the bark off the logs to reduce the risk of pests and fungal growth. This also helps with drying and makes the wood easier to work with during the turning process.
5. Storing the Wood
Drying: Store the logs in a shaded, dry area to prevent rapid drying, which can cause cracks. You can also stack the logs with spacers to allow airflow.
Time: Allow the wood to season for several months to a year depending on its thickness and species. Proper seasoning ensures that the wood stabilizes and is ready for turning.
6. Preparing for Turning
Cutting Blanks: Once the wood is sufficiently dried, cut it into turning blanks, either cylindrical or square shapes that are appropriate for your project. This step is crucial in ensuring that the wood is ready for the lathe and that the final piece will have the desired shape and finish.
Mounting: Ensure the blanks are properly mounted on the lathe using a faceplate or a chuck. This will secure the wood and allow you to control the turning process effectively.
7. Final Preparation
Checking Moisture Content: Use a moisture meter to check that the wood has reached a suitable moisture content, ideally around 8-12% for indoor projects. Proper moisture content ensures that the wood will not warp or crack during the turning process.
Turning Orientation: Consider the grain orientation for the desired finish and strength of the final piece. Proper orientation will enhance the aesthetics and durability of the turned wood.
8. Turning
Turning Techniques: Use appropriate tools and techniques while turning to achieve the desired shape and finish. Follow safety guidelines and proceed step-by-step to ensure success.
Finishing: After turning, sand the piece to achieve a smooth finish and apply a suitable finish such as wood polish or a paint to protect and enhance the wood's appearance.
By following these steps, you can effectively prepare a live tree for turning on a lathe, ensuring a successful and enjoyable woodworking project. Proper preparation and attention to detail will result in superior quality turned pieces that showcase the natural beauty of the wood.
