Shop Problems in Sheet Metal for Secondary Schools 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. As 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 influenced 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.
