3. scraping process Fig 12 Shows the two types of chisel CUTTING AND SCRAPING To make a cut the chisel should be held so that the sharp edge actually digs into the revolving workpiece shavings should now peel off To scrape the chisel should be held at a right angle to the surface of the workpiece fine pieces of wood will be produced when scraping instead of shavings Fig 13 Many operations require the cutting chisel to be used for scraping but scraping chisels are very rarely used for cutting Scraping will blunt dull a chisel much faster especially when using razor sharp cutting chisels Cutting is much faster than scraping and produces a much smoother finish Cutting is more difficult than scraping but scraping is more precise and easier to control 10 BASIC WOOD TURNING 10 4 KNOWING WHEN TO CUT AND WHEN TO SCRAPE FIG 14 There are two different approaches to the work when turning The first is towards a circumference of the gt workpiece eg When turning down the outer surface of a Y cylinder or the inner wall of a hollow round box Using m this method the surface being turned travels under the edge of the chisel like an endless belt The second approach is towards the diameter of the workpiece as when turning the face when faceplate turning or the side of a large shoulder when spindle turning using this method the surface being turned rotates like a disc under the chisel edge Some jobs will requi
