Stringing the Brinsmead….

Stringing the Brinsmead….

A fine game played slowly….! The screw thread tuning system (known on upright pianos as a “top tuner” – because the threads point straight up) is very stable, but rather tricky to work with at the stringing stage.

Also note the newly capped treble bridge.

    Fascinating read your blogs on the Brinsmead with the screw thread tuning system. I’m really fascinated about this type of tuning system – wish you could post more on it. This particular model benefits from both having the screw thread tuning and being straight strung – a rare combination ! I wonder how this combination of technical solutions translated into the sonic character of the instrument.

    Would you recommend acquiring such a piano on the benefits of this tuning system alone ? What about its sound qualities ? anything to write home about ? Also, I didn’t see much about the action in your posts. I’d assume it doesn’t have the full repetition mechanism of a concert grand piano ?

    Thanks for reading

    No two screwstringers are ever the same. Most fascinating to see this design–thanks for posting!

  3. H! Can you tell me the name of this Brinsmead top-runer, or at least its serial number? Thanks

      Goodness me – not sure how it’s taken so long to find your comment – many apologies! The serial number of the piano is 31406, so it was built c.1880. As I recall, the piano was around 7′ in length, and had a most peculiar soundboard design that allowed shape to be added after the fact by tightening a row of screws just beyond where you’d find the dummy bar (cutoff bar) in the bass front corner of the piano. I can see that properly used this feature could be helpful, but at the same time it would be very easy to wreck the piano…!
