Excerpt from Precision Locating and Dividing Methods<br><br>The degree of accuracy that is necessary in the construction of certain classes of machinery and tools, has made it necessary for tool makers and machinists to employ various methods and appliances for locating holes or finished surfaces to given dimensions and within the prescribed limits of accuracy. In this treatise, various approved methods of locating work, such as are used more particularly in tool rooms, are described and illustrated. These are not given, in every case, as being the best possible method under all conditions, because, as every mechanical man knows, the best way may be dependent upon the element of accuracy with little regard for the time required to do the work, or this order may be reversed; therefore, one method is seldom, if ever, the best under all circumstances, and it is necessary for the workman to consider the conditions in each case and then be guided by his judgment and experience in determining just how the work should be done.<br><br>About the Publisher<br><br>Forgotten Books publishes hundreds of thousands of rare and classic books.
