Not illustrated. 1913 edition. Excerpt: ...and 176 and pulled towards you, cutting a very fine shaving. Sometimes it is moved in the opposite direction as shown in Figs. 177 and 178, but for your work and small hands, you had b etter pull it toward you and if it is necessary to work in the opposite direction, you should usually either change your position or the position of the piece. You can change the angle at which it is held in order to avoid its "chattering" or making small irregularities in the surface. Notice that the angle it makes with the surface of the board is the same in all the pictures. This angle should not vary and should be as nearly a right angle as will allow the scraper to cut. The more firmly you hold the scraper, at the proper angle, the better it will cut and the longer it will keep sharp. It should cut a fine shaving without tearing the surface on any hard wood, whether moved with the grain, as in planing or against the grain. It is because it cuts smoothly against the grain that it is so useful for woods which have grain in both directions. Only by using a tool which cuts smoothly against the grain can such woods be properly finished. In your use of the scraper, be careful to see exactly how and where it is cutting. Do not scrape more than is necentse55a1'Y-some Places Fig. 1 7 7 Using Scraper, Pushing will require no scraping; some spots of torn grain will require a great deal. Sometimes you will need to scrape places which are smooth, in order to make the entire surface level. A most important matter is Fig. 1 76 Using Scraper, Pulling to avoid scraping the soft grain lower than the hard grain. Fig. 179 shows a surface with lines drawn to indicate the various positions of the scraper in finishing it. The lines are placed on different form
