[pianotech] Toy piano scaling

[Joe And Penny Goss]

Hi David,
Do what they did and--- Cut the tine a little long if you must err, then
grind off the tip make the pitch go up add a little solder when just a
little sharp and file off solder
to lower the pitch back up to to where you want it.
Filing the solder can be done with the tine installed.
