Scale Model of International Harvester Titan Works

International Harvester Titan Type D scale model project showcases lifetime achievement in model design and construction

| April 2013

Inspired by a 1994 magazine article on a 25 hp International Harvester Titan Type D tractor restored by LeRoy Baumgardner Jr., Don Hermann set out to make a 1/8-scale model of that same tractor.

Don, a retired farmer from Genesee, Idaho, had purchased a metal lathe when he was discharged from the U.S. Army several years earlier. Since then, while building several model engines, he has definitely achieved the status of master machinist. Don’s talents with the lathe are mainly self-taught. He is one of a unique cadre of Pacific Northwest machinists who have developed great friendships through the activity of building scale models. Don is a member of the Lewis-Clark Antique Power Club, Lewiston, Idaho.

International built the 25 hp Type D from 1910 to 1914. According to C.H. Wendel’s Standard Catalog of Farm Tractors, the model was originally sold as a 20 hp tractor but was upgraded in about 1912. A single-cylinder engine was used.

Working scale model

What makes this model so special and unique? Several things, including the fact that the unit actually runs. This scale model gas engine runs on gasoline; the working powertrain propels the unit across the floor at a speed of 40 feet per minute.

The model is accurate to scale and intricate detail. Don made special efforts to convert the bar stock metal used to fabricate parts so that they resembled the casting patterns commonly found on machinery manufactured during the early 1900s. He purchased a 25 hp IHC Famous engine kit that fit his scale, but he fabricated all other parts.

Don’s special care in building this model paid off. Incredibly, all of the parts fit on the first try and not one had to be re-made. Don’s son-in-law made the decals and the wooden base that holds the tiny Titan. The base unit includes rollers under the wheels, so the unit can be operated in place.
