As an activity that involves extensive use of metalwork machine tools in a home workshop-based context, model engineering overlaps with other artisanal machine-tool based and allied metalwork pursuits including gunsmithing (particularly in the USA), manufacture of home metalworking tools and accessories, home cnc equipment building, antique machine tool collecting, antique vehicle and machine restoration, home welding and hobby metalcasting. Model engineering is closely associated with the hobby of running live steam locomotives, and overlaps to a degree with the making of non-working models, particularly those of mechanical subjects. Products such as Meccano and low-pressure toy steam engines have a loose affinity with model engineering, stemming from the production of scientific and mechanical toys beginning in the late 18th century. Steam Punk, a post-industrial sculptural art style picking up on the aesthetic and kinetic qualities of old machinery, shares some overlap.
