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

FILE FILOSOPHY Testing Machines A great deal has been said or written about file test- ing machines for determining the comparative efficiency of various brands of files. File makers have used such machines for many years, not to determine the value of various brands of files, but to prove by an average of several tests the utility of various formations and arrangements of teeth and cut for different kinds of work. This seems to be the true function of any file testing machine. The Real Test As a general rule labor cost greatly exceeds tool cost and that tool or file or method of using is most desirable which produces the greatest output for the labor ex- pended, its initial cost usually being in very small ratio to its general result. Hence the best and fairest test of the value of a file or brand of files is its effici- ency per $1.00 of pay roll. Summary Select the proper shape and cut of file for the work. Handle properly. Have work properly secured and at a convenient height. Hold file in a manner to give best control. Keep pressure on file sufficient to keep it cutting— less for a new file—more as it becomes dulled—but fieep it cutting. Keep file clean—a dirty file is a dull file. Clean surface of work to be filed. Take good care of your files. Don’t abuse them. They are cutting tools. NICHOLSON FILE CO. 28
