Being some Hints regarding the proper Methods of using Files and the various Applications of the most common Files

FILE FILOSOPHY Filing Large Table Surfaces In filing large table surfaces, the tang is frequently bent upward to admit of the hands clearing the work when the file passes over the surface; sometimes a crank-shaped holder is employed, having one end fit- ted to the tang of the file while the other is fitted to receive the handle. These devices, while facilitating somewhat the handling of the file, do not give that perfect control which enables the operator to manip- ulate it at will, nor do they aid in governing its convexity. The Improved Surface File Holder, herewith illus- trated, is designed, especially to meet these points, thus enabling the skillful operator to do much of the work with the file which has hitherto been done with the scraper. Height of Work For filing in a vise the work should be held as rigidly as possible and the vise jaws should be placed so as to be level with the elbow of the workman, which will be found to range from 40 to 44 inches from the floor—therefore 42 inches may be considered as an average height, best suited for all heights of workmen, when the vise is to be permanently fixed.
