Building the Myfordboy Steam Engine Part 2 Flywheel
У вашего броузера проблема в совместимости с HTML5
The video shows how the flywheel is turned from a zinc/aluminium casting. This material turns very well and can be given a mirror finish if required. It is also heavy so makes a good flywheel.
I have castings and plans for sale to build this engine. Details are at http://myfordboy.blogspot.co.uk/p/the-myfordboy-steam-engine.html
