[pianotech] Geo Broadbent Tuning Pins

[Dave Smith]

Tom, its hard to photograph but I had described the top’s dimensions, about .2”x.26”  rect or oval as you say, but most pins were more rectangular than oval  ..  here is another pic.

Dave, you are not showing us the shape of the top of the pin.  That's what we need to know to answer your question.  I presume it's a standard oval pin from the 19th century.

  I encountered a Geo Broadbent straight-strung grand piano with tuning pins as shown. Piano is over 100 years old. Although the pin shown is a bit chewed up from some previous tech (not this one) using vise grips, it it pretty close to the other undamaged ones still in the piano. No tuning lever tip I have seen will fit this, as the pin is rectangular in shape, .2”x.26” roughly. The pins are threaded into the block with a pretty coarse thread. 

  Does anyone know where to find a hammer tip that would fit this type pin? The piano was moved here from South Africa, where apparently the techs had no trouble tuning it :}

  Also the piano is sitting at about 100c flat to A440, but I was assuming it was designed to be tuned at A415 anyway. Any thoughts on this also? Thanks
