With the free metalworking plan that you can download on this page you can make a Contour gauge.
240mm (9.45'') x 309mm (12.17'') x 35.5mm (1.4'')
The universal mechanical contour gauge (shape copying and controlling tool) that we present in this project is especially useful for modeling ships and airplanes, but not just that. Because of its simplicity, you can use it for copying and controlling various curved surfaces on working items. This tool is also convenient for checking out curves - for example, while making a turning template, etc. Also, you can easily adjust construction to your needs by changing some dimensions, or in another words you can decrease or enlarge the whole assembly to suit the regular dimensions and tools for your line of work.
