The little engine that could! The most amazing model you're ever likely to build. A steam engine - or more accurately, a steamless steam engine - made entirely from paper. Modeled after toy steam engines popular in the US during the late 19th and 20th centuries, this miniature, fully-functioning machine relies on air pressure supplied by an inflating balloon to push a piston which then pushes against a crankshaft, causing rotation of the shaft. It was this rotating shaft - in real steam engines - that powered the Industrial Revolution.

This is an involved build and you will not be able to complete this in one sitting. Plan to work on one section at a time, following the instructions carefully. You'll notice there are many small numbered pieces instead of labeled pieces. To keep form getting confused, write the correct number in pencil on the back of each piece as you cut it out. Keep track of how far you have come by checking off the steps as you go. Study the construction diagrams thoroughly and carefully. You'll notice that many parts are visible in more than one view. Finally, work as accuraretly and precisely as possible. Remember this is a real working engine and they take time to build!
