Woodworking Wood Turning Tools Sharpening Techniques Detailed Explanation
Before you can sharpen a Turning Tool, the bevel angle must be ground properly. The grinding requirements of cutting and scraping tools are very different because of the wav they are used on the lathe. The bevel of a cutting tool must rub on the stock at all times to help control the cut. lf the angle is too sharp, the tool will be harder to control and the cutting edge will dull quickly. But if the bevel angle is too steep, you may have to hold the tool almost vertically and apply excessive pressure. Scrapers, on the other hand, shave away wood with a burr. The angles they require depend on the type of scraper you are using.Visit the Wood Turning pages for more wood turning info..
Not only bevel angle, but the shape of the tip-whether straight across, skewed at an angle, or curved-is important to consider when grinding your tools. A square-ground Spindle Gouge, with a tip ground perpendicular to the blade shaft, is best for turning cylinders, tapers, or other straight cuts. A fingernail-ground spindle gouge, with edge corners cut back, or relieved, will make a better tool for turning beads and coves. Skew chisels may be ground straight across or curved, depending on the use.
As you grind a bevel, it is critical to create a single-faceted bevel, that is, one with a continuous face. This can only be achieved by keeping the bevel perfectly flat on the wheel as you grind. The jig will help you with a troublesome tool, the roughing-out gouge. If you use a grinder, the bevel will have a shallow concave shape, matching the curve of the grinding wheel. Avoid using a wheel smaller than 5 inches in diameter; the degree of curvature will make for a weak tool tip. Grinding on a belt sander will-yield a flat bevel, which is equally effective.Visit the Woodworking Plans Website pages for more woodworking articles.
