Bigger hammer theory in practice, the building of Trabant cars in the 1980's

Skip the first 22 seconds, it's boring, after that they get to hammering for proper fitment

If you haven't heard of the bigger hammer theory, you aren't a submariner or a mechanic. The theory is this; if it doesn't work, hit it with a hammer (known in scientific circles as mechanical agitation (thank you XO Joachim) ) if it doesn't work after hitting it with a hammer, hit it with a bigger hammer. If it still doesn't work, replace it... it's broke.
