Publisher's Synopsis
Excerpt from Essentials of Sheet Metal Work and Pattern Drafting: An Elementary and Advanced Course for Vocational and Trade School Students and Apprentices
This book is written in answer to numerous requests for information regarding courses in sheet metal, suitable for grade and high schools, coming from school people who are introducing sheet metal work into the regular school curriculum. Realizing the need for a correlated course in practical sheet metal work and pattern draft ing in text form, it is offered, therefore, to industrial teachers, students, apprentices, sheet metal workers and others interested in this subject.
The problems presented follow the lines of the best shop methods, derived from years of experience in teach ing the subject and as a practical sheet metal worker. The course is outlined and the problems are presented in such sequence that the processes and machine operations are reviewed with each new problem.
It is not expected that the problems as given will be strictly copied, but rather that they will make clear the methods and processes that may be applied in the con struction of similar problems. The proper sequence, so necessary for successful instruction in sheet metal pat tern drafting, is an important feature of this course. Many of the problems are only partly solved, which pre vents the student from copying from the text and com pels him to develop his powers to think as well as to draw.
It is desired that the work shall be regarded as a col lection of data presenting the essentials of sheet metal working, rather than an attempt to produce a series of models.
