Freewheel oscillates - why?

[Ugo51]

Hi guys,

I noticed the freewheel oscillates when spinning. It's been doing it since day 1, so it doesn't really depend on wear, although it might have gotten worse with time.
Is it normal? I don't think so, so I'm asking, what is it caused by? Is it the freewheel itself that is crappy, or maybe the axle is bent? Doesn't look like this is the case to me, unless a very minor bend can cause such a macroscopic oscillation
Here a video of it in action:

Very slight out of roundness of axle/locknuts/freewheel/etc/stuff.

Most freewheels/cassettes/wheels do it to a degree. Unless you're talking higher end stuff.
Unless it's moving enough to affect shifting or chain retention, rattling/loose, or is actually binding at any point, it's generally not worth trying to fix.

Parts machined a bit off. Back in the 50s Regina were particularly variable.
The hub axle would only affect this if the axle was rotating.

Thanks. It doesn't seem to affect anything, so I'll let it be.
For a while, at least.
I might want to upgrade to a 7 speed freewheel at some point

Most freewheels I've ever had do it to some degree.
