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

FILE FILOSOPHY The File Card and File Brush will be found excellent tools, and master mechanics should see that every file-user in their employ is furnished with one or the other of these, and insist that they be used, if they wish to economize in the wear of their files. Copper and Copper Alloys Metals like copper, or brass with high alloy of copper, require a very sharp keen file, preferably of specially shaped teeth, just as these metals require a sharper pointed, keener lathe or planer tool. Special work may require a special file, but stock shapes and cuts will usually be found to meet nearly all requirements. Care In Putting Away One of the most destructive customs is that of loosely throwing files, fine and coarse, small and large, into a drawer filled with cold chisels, hammers, turn- ing tools, etc., and then throwing the chisels, hammers and other tools on to the files. When we consider how small a portion of the points of the teeth is worn off by extreme wear when the file is properly used, and that to effectually dull them for some kinds of work requires but slight knocking upon a hard substance, it will be easily seen that the evils of this habit should be more carefully considered by the master mechanic, and suitable pro- vision made to avoid its destructive tendencies.
