You've asked the classic risk acceptance question...
What happens if the tower fails? Death, destruction, disaster? Or
just minimal financial loss from broken parts?
Somewhere down the road, diligent as you may be, you might not be
able to crank it down (maybe you're sick in bed, maybe the power
fails, maybe the tower gets stuck, and you're not about to go out in
the rain and storm to fix it). stuff happens.
So, you look at what are the consequences of a worst case scenario, a
normal scenario, and a best case scenario, and decide, for yourself,
what you're willing to accept.
If there's a regulatory agency involved (e.g. city ordinances), your
risk policy may be determined by "the rules".
Jim.
