[pianotech] Knee board & pedal squeak

[Thomas Cole]

This kind of squeak often occurs at places where the knee panel contacts 
the opening. Remove the panel and the squeak goes away.

Operating the pedal flexes the pedal rail causing the panel which rests 
on it to move up and down against the opening, typically at the upper 
corners. VJ lube or other heavy consistency lube is usually the fix.
