As an experienced woodworker and craftsman, I’m excited to share my insights on the selection and maintenance of woodturning chisels. These versatile tools are the backbone of any successful woodturning endeavor, enabling us to shape, sculpt, and refine our creations with precision and finesse.
When it comes to woodturning, the choice of chisels can make all the difference in the world. From the aggressive roughing gouge to the delicate skew, each tool has its own unique characteristics and applications. It’s crucial to understand the nuances of these instruments and how to properly care for them to get the best results.
Let’s dive into the world of woodturning chisels and explore the secrets to selecting the right tools for your needs and keeping them in peak condition.
Selecting the Appropriate Woodturning Chisels
One of the first decisions you’ll need to make as a woodturner is which chisels to add to your toolkit. The selection can be overwhelming, with an array of shapes, sizes, and grinds available on the market. However, by understanding the specific functions of each type of chisel, you can build a well-rounded collection that will serve you well.
Roughing Gouge: This wide, straight-edged tool is the workhorse of the woodturning world. Its primary purpose is to quickly remove large amounts of material, transforming a square blank into a rounded shape. When using a roughing gouge, it’s crucial to maintain a firm grip and a steady hand, as the tool can be quite aggressive if not handled properly.
Spindle Gouge: Similar to the roughing gouge, the spindle gouge is designed for shaping spindle-work, such as table legs, balusters, and other cylindrical projects. With its narrower profile and more pronounced flute, the spindle gouge allows for more precise control and the creation of delicate details.
Bowl Gouge: This deep-fluted gouge is the go-to tool for turning bowls, dishes, and other forms with curvaceous profiles. The bowl gouge’s versatility allows it to be used for both shaping the exterior and hollowing out the interior of these types of workpieces.
Skew Chisel: While some woodturners have a love-hate relationship with the skew chisel, this tool is a valuable asset in the right hands. The skew’s sharp, angled edge can produce incredibly smooth, refined surfaces with minimal sanding required. However, it does demand a certain level of skill and technique to use effectively.
Parting Tool: As the name suggests, the parting tool is used to separate, or part, the workpiece from the lathe. It’s an essential tool for tasks like creating tenons, forming beads, and cutting grooves. When using a parting tool, it’s important to take care not to cut all the way through the workpiece, as this can lead to unwanted damage.
In addition to these core chisels, you may also want to consider adding a few specialty tools to your collection, such as a bedan for creating details, a hollowing tool for excavating the insides of bowls, or a negative-rake scraper for delicate finishing work.
Maintaining the Cutting Edge: Sharpening Woodturning Chisels
Sharp tools are the foundation of any successful woodturning project. Dull chisels not only make the work more arduous but can also increase the risk of accidents and damage to your workpiece. Mastering the art of sharpening is a crucial skill for any woodturner to develop.
There are several methods for sharpening woodturning chisels, each with its own advantages and drawbacks. The choice of sharpening system often comes down to personal preference and the resources available in your workshop.
Bench Grinder: A bench grinder is a common and accessible tool for sharpening chisels. The key is to use a slow-speed grinder (1,800-3,600 RPM) and to keep the tool cool during the sharpening process, as excessive heat can damage the temper of the steel.
Water Sharpening System: Systems like the Tormek or Grizzly wet grinders offer a more controlled and precise sharpening experience. The slow grinding speed and water-cooled environment help to maintain the integrity of the tool’s edge.
Hand Sharpening: Some woodturners prefer to sharpen their chisels by hand, using a series of increasingly fine-grit sharpening stones or diamond plates. This method allows for a more customized edge, but it requires a keen eye and a steady hand.
Regardless of the sharpening system you choose, the key is to develop a consistent technique and to maintain the appropriate bevel angle for each type of chisel. This may involve some trial and error, but the rewards of having razor-sharp tools cannot be overstated.
Protecting Your Investment: Proper Tool Maintenance
Keeping your woodturning chisels in top condition isn’t just about sharpening; it also involves proper storage, handling, and cleaning. These practices will not only extend the life of your tools but also ensure that they perform at their best every time you use them.
Storage: When not in use, your chisels should be stored in a safe, secure manner. Consider investing in a tool roll or a dedicated chisel rack to keep them organized and protected from potential damage.
Handling: Treat your chisels with care when using them on the lathe. Avoid applying excessive force or putting them through unnecessary strain. Always keep a firm grip and be mindful of the tool’s position relative to the spinning workpiece.
Cleaning: After each use, take the time to clean your chisels thoroughly. Remove any built-up debris or residue using a soft cloth and, if necessary, a mild cleaning solution. This will help prevent the formation of rust and maintain the tool’s cutting edge.
Rust Prevention: Speaking of rust, it’s important to take proactive measures to protect your chisels from this common nemesis. Consider applying a thin coat of rust-inhibiting oil or wax to the tool’s surface, especially on the cutting edge.
By following these simple maintenance practices, you’ll be able to keep your woodturning chisels in peak condition, ensuring that they serve you well for years to come. Remember, well-cared-for tools are not only more efficient but also safer to use, reducing the risk of accidents and costly damage to your precious woodworking projects.
Exploring the Versatility of Woodturning Chisels
While the core set of woodturning chisels we’ve discussed so far are essential for tackling the majority of your turning tasks, the world of these tools extends far beyond the basics. As your skills and experience grow, you may find yourself drawn to exploring the unique capabilities of more specialized chisels.
Bedan: The bedan is a specialized tool used for creating details and textures on turned pieces. Its sharp, pointed tip allows for the precise removal of small amounts of material, making it ideal for tasks like bead and cove formation.
Hollowing Tools: For those who enjoy creating bowls, hollow forms, and other vessels, a set of hollowing tools can be a game-changer. These specialized chisels, often incorporating a carbide tip or a hooked design, allow you to excavate the interior of your workpieces with greater control and efficiency.
Negative Rake Scrapers: Scraping tools may not have the same allure as the more dynamic cutting chisels, but they play an important role in the finishing process. Negative rake scrapers, in particular, excel at smoothing and refining surfaces without causing unwanted tear-out.
Specialty Grinds: Beyond the standard straight and swept-back grinds, some woodturners prefer to experiment with custom chisel geometries. For example, a deep-fluted bowl gouge with a long fingernail grind can provide exceptional control and cutting ability when shaping the interior of a bowl.
