There are scores of videos of common people just
like you and me replacing our torsion springs.

Winding a spring is "almost" trivial.

The only thing that makes it decidedly not trivial is
the dire consequence of something going wrong.

However, the spring-winding task, in and of itself,
is quite trivial for a man of normal strength.
