Excerpt from Shop Problems in Sheet Metal for Secondary Schools: With Notes on Equipment, Materials and Shop MethodsAs an introduction to this little collection of notes and drawings the author wishes to call the attention of High School boys especially to the fact that this trade has not received the attention it deserves from the schools. In recent years several vocations such as printing, concrete construction, automobile repair and electrical work have found a place in the schools while others seem to be losing ground. It seems to be true that trades such as blacksmithing and molding which have been in¿uenced by the introduction of new machinery which is more or less automatic, have become less attractive to boys.Sheet metal work as a vocation has many attractive features. Lt is a large and growing industry represented both in the building trades and in modern automobile construction, furniture and boat building and in the construction of manufactured articles. The introduction of autogenous welding and electric welding has done much to make possible the use of sheet metal in new forms.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
