very strange tuning mechanism

[Tom Servinsky]

The Mason & Hamlin uprights had a system called the "screw stringer" system will sounds very close to what you are describing. Unusual, but stable system.

  Subject: very strange tuning mechanism


  in some old pianos (very seldom) we find very strange mechanisms for tuning, i.e. without tuning pins. Instead of the pins there are screws. The function is like the fine tuning screws of violins. Did you ever see such mechanisms? I saw 2 of them in the last 10 years: one Crasselt & Raehse and one Gebr. Meusel, Hamburg. Have you ever heard of Meusel? I could find nothing with Google and my Lexikon Of German Pianomakers says nothing, too. And in a book I read about Emil Lämmerhirt, Berlin, who constructed pianos with a "Patentschraubenstimmung" (patent screw tuning).

  I regret that I had no camera to make pictures of these historic interesting instruments. Has anybody else fotos of these mechanisms? At least that Crasselt & Raehse had a very stable tuning. I came back after 3 years and the tuning was still fine.
