... Where formerly but few men in the shops were directly interested in ... the methods by which the holes in a jig could be accurately located and bored, today there are thousands of toolmakers who are employing refined processes, precision tools and appliances for executing this class of work. Many methods and devices originating in watch factories and similar establishments for accomplishing very accurate results were for a considerable period confined almost exclusively to such institutions ...
The master plate, disk, button and refined test indicator processes have been extended from watch-tool to other classes of accurate tool work ... Closely allied with these devices ... is the compound microscope, which with cross hairs and conveniently arranged micrometer screws constitutes a testing and measuring appliance having an innumerable number of practical applications in connection with the work of the tool-maker.
We have endeavoured in the following pages to present, in convenient form, information on various phases of tool work...
There is no branch of tool work more important or more interesting than ... these methods, including the use of master plates, buttons, disks, size blocks, etc., have therefore been treated at length, together with processes of making master plates for various purposes, the use of test indicators, accurate gages, the microscope and other appliances.
