Brass MS 63 In model making, there are many different types of sheet metal that can be used for different purposes. For example, sheets of steel, aluminum or copper can be used to build frames, housings or other mechanical parts for models. They can also be used to represent details such as wheels, screws or coins.
One of the most important things to consider when using sheet metal in model making is the thickness of the material. As a rule, you should use sheets with a thickness of 0.5 to 1 mm, as they are easy to work with, but still strong enough for use in models. If you use sheets with too little thickness, they can be easily deformed or damaged, while sheets with too much thickness can be difficult to machine and process.
There are many different techniques used in model making to machine and shape sheet metal. These include punching, bending, sawing and grinding. Some techniques require special tools, such as punching machines or bending jigs, while other techniques can be done with standard tools such as pliers, saws or sandpaper.
Overall, sheet metal in model making offers many opportunities to build and design realistic models. They are an important part of many modeling projects and offer the possibility to create detailed and realistic models.
