You may start to notice that a lot of solo craftsmen, or shops with a handful of people, often rapidly move from typical grade machinery to very heavy duty machinery once they become busy enough that constant maintenance of sheetmetal or light casting machines is too time consuming. One of the reasons for that move is that the really heavy stuff, especially before the age of electronic everything, does not come out of adjustment and doesn't break. They run for a very long time with minimal maintenance outside of normal oiling.

Compare that to modern machinery commonplace in their 'classical' lines, which is constantly wearing out and needing maintenance.

It would turn out that the modern interpretation of 'overbuilt' is actually properly built and the light stuff common everywhere now is much undersized for professional work.
