THE scraper illustrated by Fig. 411, and shown handled by Fig. 412, is an aid in producing surfaces more flat and regular than can be produced with the plane alone. Its use does not dispense with the plane; on the contrary, any surface on which the scraper is to be used must previously be planed as level and smooth as plane can make it. But the plane, in doing its work—no matter how sharp it may be, or how closely the back-iron is set up to the edge of the cutting iron, or how straight across the edge the cutting iron is sharpened—is liable to leave marks and ridges on the face of the work, which, on hard woods, are not effectively removed by the use of glasspaper alone. The scraper is used after the plane has finished its work, and previous to the final operation of glass-papering. In addition to the removal of the ridges left by the plane, the scraper is used for dressing up all kinds of cross-grained surfaces that occur in curly and figured solid and veneer woods; but as far as possible this use of the scraper should be avoided. Excessive dressing up of a cross-grained patch on a panel, a stile, or a tabletop will most certainly show, and spoil the flatness and general appearance of the article when it is polished. As a rule, such excessive scraping is resorted to in consequence of the plane having been sharpened and set badly, or of some other technical oversight or unskilful manipulation.
