Narex 6 Piece Set Unhandled Premium Chisel User Manual

การแนะนำ

This manual provides essential information for the Narex 6 Piece Set Unhandled Premium Chisels. These high-quality chisel blades are designed for craftsmen who prefer to customize their tools by fashioning their own handles. This set includes six chisel blades of varying sizes, along with brass ferrules and leather shock washers for handle attachment.

The Narex unhandled chisel blades are manufactured in the Czech Republic from fine-grained chrome-manganese steel, drop forged, hardened, and tempered to a Rockwell hardness of 59. They are known for their exceptional edge retention and ease of sharpening. The slim cross-section sidewalls allow for access into tight spaces, making them ideal for detailed work such as dovetailing.

Setup: Attaching Handles

The Narex unhandled chisels are designed for custom handle attachment. This process allows you to create handles that perfectly fit your hand and specific woodworking needs.

ส่วนประกอบที่จำเป็น:

• Narex Chisel Blade (included)
• Solid Brass Ferrule (included)
• Leather Shock Washer (included)
• Wood for Handle (not included)
• Drill with appropriate bit (e.g., 3/8 inch for most hardwoods)
• Woodworking tools for shaping (lathe, rasp, chisel, drawknife, spokeshave, etc.)

Handle Preparation Steps:

1. Select Wood: Choose a suitable wood for your handle. American hardwoods like hickory, maple, ash, and oak are commonly used.
2. Shape Handle: Shape the wood blank to your desired handle form. This can be done on a lathe or by hand using various woodworking tools. Ensure the end where the ferrule will sit is appropriately sized.
3. Drill Tang Hole: The chisel blades feature square, untapered tangs. A pilot hole must be drilled into the handle to accommodate the tang. A 3/8 inch pilot hole is generally effective for most American hardwoods. Adjust the hole size as needed: slightly smaller for softer woods to ensure a tight fit, or slightly larger for harder exotic woods to prevent splitting.
4. Install Ferrule and Washer: Slide the brass ferrule onto the handle first, followed by the leather shock washer. The brass ferrules have an outer diameter (OD) of 0.750 inches, an inner diameter (ID) of 0.667 inches, and a height of 0.667 inches. They are annealed to prevent splitting and have inside bevels for easy insertion.
5. Attach Chisel Blade: Carefully drive the chisel tang into the prepared hole in the handle. Ensure a tight and secure fit. The ferrule and washer should be positioned snugly against the blade's shoulder.

คำแนะนำการใช้งาน

Once handles are securely attached, your Narex chisels are ready for use in various woodworking applications, including paring, chopping, and dovetailing.

General Use Guidelines:

• ความปลอดภัยเป็นสิ่งสำคัญที่สุด: Always wear appropriate safety gear, including eye protection, when using chisels. Keep hands clear of the cutting edge.
• ความปลอดภัยของชิ้นงาน: ตรวจสอบให้แน่ใจว่าชิ้นงานของคุณถูกยึดอย่างแน่นหนาamped or held to prevent movement during chiseling.
• Grain Direction: Pay attention to the wood grain. Cutting with the grain generally provides cleaner results, while cutting against it can cause tear-out.
• การลับคม: For optimal performance, ensure your chisels are always sharp. A dull chisel is more dangerous and less effective. Refer to the Maintenance section for sharpening details.
• การจับคู่: For fine shaving or cleaning up joints, use a paring action by pushing the chisel with hand pressure, often with the bevel down.
• การสับ: For removing larger amounts of material or cutting mortises, use a mallet to strike the handle. Ensure the chisel is held firmly and guided accurately.
• Dovetailing: The slim sidewalls of Narex chisels are particularly suited for dovetail joints, allowing access into tight corners.

การซ่อมบำรุง

Proper maintenance is crucial for the longevity and performance of your Narex chisels. This primarily involves sharpening and protecting the blades.

การลับคม:

The Narex blades are easily sharpened and hold an exceptional edge. For optimal performance, two key steps are required:

1. Flattening the Back: Before initial use and periodically thereafter, the back of the chisel blade will need to be flattened. This creates a perfectly flat reference surface essential for accurate sharpening and clean cuts. Use a sharpening stone or abrasive paper on a flat surface, working through progressively finer grits until the back is mirror-polished near the edge.
2. Sharpening the Bevel: The bevels are factory ground to 25 degrees. Maintain this angle when sharpening. Use a sharpening jig or freehand technique with sharpening stones (waterstones, oilstones, diamond stones) of increasing grit. Finish with a very fine grit stone or stropping compound to achieve a razor-sharp edge.

การจัดเก็บและการป้องกัน:

• After use, clean any wood dust or residue from the blades.
• Apply a light coat of camellia oil or a similar rust preventative to the steel blades, especially if storing for extended periods or in humid environments.
• Store chisels in a way that protects their edges from damage, such as in a chisel roll, tool cabinet, or with edge guards.
