Blueprinting e-bog

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The subject of blueprinting has, up to the present time, received little or no attention in a popular form as a subject in itself. Brief treatment has been accorded it in a number of books on mechanical drawing, and in a few magazine articles. Such treatments, because of their publication as isolated articles or parts of larger works, have in most instances presented only a brief resume, enough to give a general understanding of some particular phase of the subject. The object of this book has been to present practical in formation about blueprinting and such practices as are in current use, in a form which will be of most service to blue printers. It has been written in simple language with the view of its being used by students and others not familiar with the subject; and it is hoped that the subject will be so presented that more blueprinting especially in school shops will result. With the exception of a few instances in this work the author makes no claim to originality. If the publication of this book will lead to a better understanding and practice in blue printing, especially by students, it will have accomplished its object.
