Of the "series"....it's always me...who....r.....pe..I can't do anything about it unfortunately...this time I stumbled upon the bar activated by the right pedal "of resonance"...and I ask our PAOLO, is that bar cam-shaped?? in the sense that when it is activated by the pedal, it raises the end of said bar which, rotating clockwise and having that special oval shape, simultaneously activates the blades... or not?????????

I am asking you because in all the photos I have and the various drawings, the operation is NOT clearly understood....I even made my own little drawing to study its mechanism..........help me please PAOLO, YOU WHO CAN.

A BIG HUG...

The pedal operates a metal axis that pushes up a felted flat rod, which in turn simultaneously raises ALL the dampers.
