  • Grinding curved edge knives - The Pegbox - Maestronet Forums

    I don't know about using a Tormek, but you can hollow grind a curved edge using a CBN wheel, or any other type of standard wheel, mounted on a bench grinder. I use a Veritas grinder tool rest to keep the blade at a fixed angle to the wheel.

    curves it can also be used on inside curves by applying a very gentle touch along the edge of the belt. Wet Belt Sander Belt Choice You can use cork, diamond, felt, or silicone carbide belts on a wet belt sander. Diamond belts work fastest but are so pricey most people prefer silicon carbide for grinding and cork or felt for polishing.

  • Knife Edge Geometry Types for custom made and forged knives

    The convex grind arcs down into a convex curve (arcs out) towards the edge. The convex grind is similar to the sabre grind in that it (typically) still has a lot of steel in the middle of the blade, making it the thickest of the three main types of grinds. This puts extra steel behind the edge, reinforcing and strengthening it.

    A Few Definitions. Concave – shapes that curve inward, like an hourglass. Think of how a cave curves in, or think "con-cavity". Convex – shapes that curve outward, like a football.. Spine – the back of a blade, opposite of the edge.. Primary Bevel / Grind – Where the knife first begins to narrow into a cutting edge from the thickness of the main stock of the blade.

  • Toroidal grinding method for curved cutting edge twist ...

    A toroidal grinding procedure that provides an accurate and effective grinding for the main curved cutting edges of a twist drill had been developed. Within this procedure, the clearance surface of the twist drill is a cylindrical helicoid surface with a constant pitch, and the curve generated during the grinding procedure represents the main ...

  • NURBS toolpath planning for glass sharp corner edge grinding

    In this paper, a transition toolpath planning algorithm is proposed to achieve sharp corner edge grinding in personalized glass products manufacturing. The developed algorithm is based on a segmented conic NURBS curve with parameterized knot and weight sequences. First, the requirements for glass sharp corner grinding are given, and a transition velocity constraint is derived based on a ...

  • Stellafane ATM: Rough Grinding

    GOAL: You have completed rough grinding when you have: Removed enough glass to reach you target sagitta (±0.001") The curve you have ground extends evenly and smoothly to the edge of the mirror. ABRASIVE: Use your coarsest grit. This is usually for #60 Silicon Carbide, but may be #80 for 6" or smaller mirrors, and might be #40 for very large ...

  • How to sharpen a blade with a curved edge - The Pegbox ...

    I cannot imagine how people sharpen a knife with a curved edge without a jig. I know some, or perhaps most, of the best violin makers use a curved edge. Here is a simple method I worked out. I have a 6000 grit flat wetstone grinder. I inserted a PVC pipe in …

  • Carving Axe Part 2: Edge Geometry and Grinding

    Next, I created that curve by setting the grinding platform perpendicular to the wheel and grinding material directly from the edge. This operation creates a flat at the edge of the tool, which can be a useful reference point in the following steps. When I measured the curve later, it was close to an arc of a circle with an 11" radius.

  • Stellafane ATM: Guide to Strokes

    The Chordal Stroke. USE: Used at the beginning of rough grinding to initially "hog out" a lot of glass and generate the initial curve in the glass. MIRROR POSITION: Mirror on Top, Tool on Bottom ABRASIVE: Your coarsest grit (usually #60 or #80) PRESSURE: Firm downward pressure will result in short wets and faster glass removal. DESCRIPTION: With mirror on top, overhang mirror about 40% of its ...

  • Edgebanding on a Curve - WOODWEB

    Does anyone have tricks for edgebanding on a curve - both inside and outside curvatures? The banding material is pre-glued birch. Forum Responses (Cabinetmaking Forum) From contributor J: Apply the edge banding to the wood and tape it in place with masking tape. Use 2" wide tape and apply as close as need be to keep the banding tight to the wood.

  • sharpening curved edge on plane blade - FineWoodworking

    For the almost imperceptible curve of smooth planes, I first establish a dead flat edge, by moving the blade over the oils stone ( a Norton coarse/fine India combination) parallel to the edge. Then when I change to the sandpaper, at the 800 grit level,I hone in the conventional manner but I take several strokes with more pressure on the outer ...

  • A Guide to Knife Grinds and Edges – Knife Depot

    The Hollow Grind has been a historically popular type of grind, especially in the hunting community. This type of grind is concave, meaning the sides curve inward until they meet. Although the curved sides meet at a razor-sharp edge, the grind is not very durable and can dull fairly quickly.

  • Curved grind lines? How is it done? | BladeForums.com

    Jan 21, 2014. #14. Instead of grinding across the contact wheel (as in hollow grinding), orient the blade in line with the belt with the tang up. You'll want to contact the wheel at an angle (edge angled in/spine angled away). Start your grind near the ricasso, pulling the tang upward/toward you and ending at the tip.
