V-12 Curtiss D-12D Engine Construction

The scale model V-12 Curtiss D-12D engine that Alan made for his biplane model is a masterpiece. No castings were used for this scale model engine. Each piece was machined from solid stock.

Building this engine required knowledge and skill in a number of areas, from machining to cam grinding. In fact, Mr. Ingersoll designed and built his own machinery to grind the cam.

Alan’s completed V-12 Curtiss engine was removed from the biplane model and displayed at the 1998 NAMES Expo in Michigan. Alan attended the show to receive his Craftsman of the Year Award, and viewers got to admire this incredible model engine.

Cygnet Benchtop Mill

Alan designed and built this Cygnet mill himself. He even used it for some of his small projects. In 2005, Dr. Bob Kradjian donated this Cygnet to the Joe Martin Foundation.

This machine is simply too nice to sit on a shelf. Accordingly, we have put it to use for small milling projects in the machine shop at the Miniature Engineering Craftsmanship Museum.

The Cygnet is yet another example of Alan Ingersoll’s masterful machining skills.
