Files are an important tool in model making as they enable precise and accurate shapes and edges to be created on models. There are different types of files that are suitable for different materials and applications.
Probably the best known type of file in model making is the round file. It has a round cross-sectional shape and is mainly used for smoothing edges and sanding wood. Round files come in different sizes and grits, depending on how much material needs to be removed and how smooth you want the surface to be.
Another type of file used in model making is the flat file. It has an elongated shape, also in cross-section, and is mainly used for grinding metal. Flat files come in different sizes and grits, depending on how much material is to be removed and how smooth you want the surface to be.
There are also special files for specific applications in model making. For example, there are step files that are graduated in different steps and thus have different grits. These are especially useful when you want to file from coarse to fine grit without having to change tools. There are also serpentine files, which are particularly useful for filing in tight curves and corners, and wedge files, which are particularly useful for grinding away material in grooves and flutes.
Files used in model making should always be used carefully and cautiously to avoid damage to models. It is also important to sharpen the file regularly to ensure that it can perform its function well.
Overall, files are an indispensable tool in model making and can help create precise and accurate shapes and edges on models.
