This month we're encouraging everyone to take the 'Haynes Build Your Own Engine' Challenge.

It’s loads of fun for young and old and it’s a great educator about the workings of an engine. There’s no pressure in taking the challenge, it’s not a race and there are no finishing times requested. It’s designed to be taken at your leisure. The engine is a simplified version of a real car engine and the model is designed to be fun to put together for adults / kids (over ten yrs) or to teach your kids how a full-size four-stroke car engine works. It's a great starting point for anyone who is curious about engines.
