Impatience is a virtue

This miniature W32 engine is so perfectly balanced when it’s running that four coins don’t so much as twitch when perched on its intakes. Its 850 components were machined from scratch entirely by hand, and assembled with 632 individual screws. A self-confessed impatient person (though we find this extremely hard to believe after watching the assembly of the engine), Barreiro is Spanish ex-Naval Officer whose intricate model engines have been thrilling the Internet for several years.
