Celebrate over 200 years of mechanical innovation with your own fully functioning pneumatic engine. Our wooden mechanical model is a miniature version of the most successful pneumatic engine used in locomotive engines. Guaranteed to be a conversation piece at any gathering, this dynamic mini motor uses the air from a normal latex balloon to start the engine. With an integrated air pressure tachometer and built-in compartments to store the extra parts, UGears Canada has thought of everything in this highly detailed working mechanical model toy. All the parts are made precisely from high-quality plywood. Tools are not required to put your superior locomotive engine together.
