[pianotech] Little Cloth "Mutes"

[Ron Overs]

William,

>How would you go about moving the duplex bar?

Like this. Take to the plate with an angle grinder and cut out the 
original bars. Build up the plate to an appropriate profile upon 
which to mount some custom made, hardened and nickel plated new front 
duplex bars, and reassemble.

The treble bridge scale is my design from 1992, and that's why the 
bridge-pin line conforms to a curve in this piano.

This piano had a wonderfully clean top end, was a fine piano, and one 
of two older model Ds at the Sydney ABC (the other had standard front 
duplexes which we re-profiled and hardened but which were still 
noisy). Last June the ABC took delivery of two relatively 
unspectacular new Hamburg model D pianos.

Which of the older Ds did they trade? Why the cleaner sounding one of course.

I've only been tuning, rebuilding and servicing the ABC pianos for 
twenty eight years. Clearly I haven't been there long enough for my 
opinion to be trusted just yet.
