Fascinating!
Of course if anyone did it, it would be huxley.
It feels like Bowley underestimated strong vibration attacks like that and didn't invest enough in spool/serrated pins.
I suspect this is correctable, but I wonder if it would work as well mounted in a sturdy door since the vibration is not directly connecting with the pins.
