At one time when I had far fewer machines, I would do as some posters suggest and run my machines down at least once a week. I no longer bother.
However, I never
leave my machines fully wound, nor do I wind them fully. I wind them enough to play one side of a record or a single cylinder. And then I wind them between records. When I am done listening, I just walk away. At that point, the machine is probably less than ⅓ wound, and would probably slow down if I tried to play another record.
What I do think is important is to occasionally run the machines and keep them properly lubricated. If a machine sits for months or years without being played or serviced, the oil and grease may dry out, so it may not work as well when you finally do try to use it.
In 50 years of collecting, I have replaced many mainsprings -- but ONLY on newly acquired machines that already had damaged or weak springs. I have never replaced a spring on a machine I've owned for decades because it got weak. I've never had one break from over winding.
Running the machine down at the end of every playing session may make you feel good that you are "preserving" the springs, but what about the gears and bearings? You are definitely not working to preserve those since you are adding additional unneeded wear to those components.
