It was interesting reading the thread on metal to metal friction. It raised a lot of questions.
I was tuning an old Heine, about 100 years old and had E1 pop. It started flat and was sliding. Didn't give me any warning. It was still 20 cents flat when it broke. I figure someone else stressed it and it broke on me. Still, having a bass string break just doesn't sound good to the client.
When I had the action out to tie the bass wire I replaced two broken wires in the treble.
I'm looking for solutions, Not just chemicals. I figure it's not good to have gravity pulling the chemical into the bass windings. I would like to try some of Jon Page's lube but does it travel?
My first thought is to drop the pitch in the bass wire and with a rolled piece of sandpaper, Clean the wire.
The piano is in an Irish pub so I'm going back today to finish the tuning.
Also it has the steel wound strings in the duplex section. I was under the impression they had replaced the copper ones in WW2 to get copper for the war effort. I see they might be original iron clad.
Like was mentioned, Each piano of that age will be unique and require modification of technique.
I'm looking for a longer list of tools to use.
