your life's work you metal work or may be employed in a large manufacturing plant like this department in an aircraft factory factories produce huge metal furniture advertising signs laundry equipment automobile bodies and many other sheet metal products in some sections of the country and tire buildings or various parts of them may be constructed a few metal other buildings are on a method with metal work to add to the beauty of the design steepled man y buildings are covered with metal and solar roofs both of the flat pitch types a large number of houses and other buildings have sheet metal gutters and downspouts which carry the rain from the roof the gutters may be either of the open half or on time or of the square box type by means of the sheet metal break special forming attachments any desired shape and size can be developed the installation of on either new or old buildings is part of the sheet metal workers job interviewed on a great number of office and industrial buildings these may be large some have ventilators on them regardless of size nearly all metal skylights and ventilators must be especially designed each piece must be formed and fitted carefully so that the installed assembly will be exactly according to specifications and plans although for the most part furnaces are manufactured in factories where installation provides considerable business for the local sheet metal shop air conditioning and ventilating systems in stores factories and homes have greatly increased activity in the future metal field most of these installations must be especially designed the huge metal worker or contractor must many public trade schools have both day and night classes and sheet metal work there are also some reliable private trade schools offering such courses you will find instruction of this nature extremely valuable if you decide to become a sheet metal worker the forming machine is one of the most useful in the shop while with it you'll be able to roll a cylindrical shape so essential in heating and ventilating installations using a different type of machine square pipe and square boxes and pan locks when pressure is applied to the locks they are called into a tight fitting seen after a length of pipe or a cylinder is completed it may be crimped on the end with a crimping machine this is done as in the case of common stove pipe to allow the end the corresponding edges are pressed closely together by the rolls of the setting down machine and then doubles team on another machine the setting down machine is generally used where a quantity of the same kind of work is to be turned out the forming machine may be used for forming conical and tapering work that you can tops funnels metal lampshades various other articles there are many other sheet metal working machines in addition to the ones you have just seen they are all interesting to operate and essential to the sheet metal worker the sheet metal worker must be able to use a measuring instrument such as the m operations they exported metalworker must also be able to read blueprints and detail and assembly drawings when he is required to make articles simple in form that pattern can be made direct the metal from measurement if he is required to make more complicated articles it is highly important first to make a full sized drawing on paper using drawing instruments sometimes patterns are drawn on metal and then cut out and used as templates in laying out succeeding feet when a number of exact duplicate must be made you can see that a knowledge of geometry and other mathematics will be of great value many employers including the government require that their employees be at least high school many airplane parts which are made of sheet metal are formed are stamped on large presses the enormous growth of the aircraft industry has led to the development of many automatic machines and methods among the great pneumatic cameras which are used in shaping large sheets of metal usually aluminum although strictly speaking this type of work is a machine operation it takes a definite amount of skill rive holes are grilled with machines that are in large part automatic in this type of operation the grill may follow a pattern of holes in a template and they drill a large number of identical sheets that one time sheet metal airplane parts are fastened solidly together by riveting and w in some types the riveting a riveting gun is pressed against the head of the river change for the covering or skin of the plane must be carefully shaved and as free from dense as possible the size and location the rivets are accurately determined by the designers in order to obtain maximum strength with minimum one way of shipping sheet metal is by bending it over and will call states which are placed in a bench plane to hold them rigidly using a mouse or hammer the expert workman can hammer sheet metal into almost any shape desired by using stakes of different sizes and shapes he must be familiar with the use of a great many stakes and know just the right one the select for a certain job but take it away in making highly specialized parts for airplanes frequently he will make a specially designed part with only a model to guide him and he must compare his work with the model from time to time to check his accuracy sometimes he will have to make the model itself and in replacing damaged parts he will use the damaged part itself for a model and other titles to call the dolly is similar to the stake in the purpose for which it is used as with the stake the worker must know just the right dolly used for a certain piece of work instead of being with the bank the dolly is held in the hand hand work of this nature requires a very high degree of skill with the forming knowledge and a knowledge of the working properties of metal to prevent weakening and distorting the piece of work by bending i of the skills are valuable to the sheet metal worker today as long as so many products which are so useful in our modern lives are made out of sheet metal and will be jobs for skilled workers
