1895 Otto Engine

December 25 2005,
These castings were a surprise Christmas gift from my family. I have always wanted an Otto engine and this must be it. The castings were purchased from Heinz Kornmueller, Austria-Europe.   The castings are aluminum except the flywheel, gears and cylinder liner. Following pictures show some of the progress.


Drawings, CD, castings, gears, piston, liner.

Crankshaft from 4140 steel under construction.
Made the crankshaft longer so that I could install a pulley.

Taking some time but we are getting there.

Took more time then expected but essentially finished.

Well the Otto does run and, amazingly, the pendulum governor does work.  Maybe not as good as a full size one but I am happy with it.
