The Baby Ericsson
This is a 1/8 scale Ericsson Hot
Air Engine. The engine stands about 9 1/2" tall and has a bore of .900"
diameter with a .520" stroke. The castings were purchased from Myers
Model Engine Works. myersengines.com (They also have many
other casting kits.) This engine, because of its small size, does not have much power and friction has to be keep to a minimum. It
is a nice running engine and only requires a small single flame in the firebox. I run it on propane gas.
The original engine was coal fired and was located in the Henry Ford
Museum in Dearborn Michigan. Engine it self basically done. |
