Form the left side relief next. Again, create about a 10° angle. You don’t need to form a side cutting angle. The side cutting edge can be parallel to the side of the tool blank. Grind the Top Rake The top of the tool bit is ground at an angle that combines the back rake and the side rake.

Angle the gouge such that you grind off the wings with this grind. A good starting angle is around 45 degrees. Grind until the flat area just touches the nose bevel. At this point, you will have a flat surface on the entire edge of the flute all the way around the cutting surface.

line of the tool. The cutting edge needs to be completely flat and the outer tips of the cutting edge should be intact, not round-ed over. The second angle to consider is the cutting edge angle or ground edge angle (Photo.1a). The cutting edge angle of your carving tools will vary anywhere between 20° to 30°. This angle should vary in relation to the density of the timber that you are carv-

Basic Bevel (grinding) angles The angles listed on the following pages are very basic. There are many variations, especially on bowl gouges and spindle gouges, depending on the user’s level of skill and the type of turning being done. Such variations will be presented in a more advanced handout later in the year. As in all things turning,
Sharpening Turning Tools
Sharpening Turning Tools Sharp turning tools mean safer turning, better cuts and therefore a more pleasurable turning experience. A variety of tools and systems are available to keep turning tools sharp. The foremost is the dual dry wheel grinder which is available with 6 inch or 8 inch grinding wheels.

Begin by dressing the grinding wheel. Next, look up the optimum angles for the workpiece material, and then follow the steps in Figure A-I-2. Dip the tool in coolant frequently to keep it from overheating and annealing. Any discoloration on the bit indicates it was drawn and is no longer hardened. Start over again from the beginning. Tool bit angles are not critical and most tools

What to Consider When Sharpening • Bevel Angle: General term for the angle between the cutting edge and the back of the tool. Usually consists of 2 if not 3 actual angles. Not all tools are sharpened at the same angle, so before you begin to sharpen, decide what angle you are shooting for.
Sharpening Lathe Tools
• Tool grinders can sharpen spindle gouges as well. The procedure is the same as above, but the spindle gouge is placed at 70-degrees across the grinder wheel. • A Bowel grinder is also placed at 70-degree angle, while an oland tool is set at 45-degree angle against the grinder wheel.
Sharpening of Tools Class Notes
Tools, when shaped effectively and sharp will allow you to quickly carve wood held in a rapidly rotating powered vise - a lathe. Shape and sharpening is more important than the tool brand or type of steel. “Shape” is the to 3D profile and the bevel angle ground onto the cutting end of a tool.

The axial movement of the work past the grinding wheel is obtained by tilting the wheel at a slight angle from horizontal. An angular adjustment of 0o to 10o is provided in the machine for this purpose. The actual feed can be calculated by this formula(1). F=πdNsinα F=Feed (mm/min) N=rpms d=Diameter of regulating wheel(mm)

form rest accommodates the sharpening of scrapers, and also makes an excellent rest for sharpening other edge tools, such as plane irons and chisels. Adjustable locking bases secure the rests for proper tool positioning. This also allows you to grind on either wheel with both rests. The bases mount direct-ly under the grinding wheels, as shown
