This vintage film explains why manufacturing tolerances are so important.
Why manufacturing tolerances in design and manufacturing are the cornerstone of performance, without precise measuring and machining, most sports and supercars would end up being too dangerous for the road, or consuming their own engine.
Even the most basic passenger car is full of precisely fitting internal parts with clearances and tolerances much smaller than the width of a human hair. This is a side of engineering that is often overlooked, but it is as important to design and manufacturing as any other aspect, after all, how can you make power when the engine’s internals don’t fit together well?
Grab your old timey popcorn and take a look at the video below.
