The Trends UK 'Machine Works' range of build your own engine kits are comprehensive but manageable kits to construct replica working engines.

Once completed each battery-powered engine model can be turned on to reveal moving parts, lights and sounds.

Transparent housings mean you can see how a machine works from the inside outwards with the step by step manuals and videos (on selected lines) to guide you.

Some engine kits now come with a free-to-download augmented reality App which animates your finished engine model and describes key components in detail.
