[pianotech] help

[Ursula Hammerling]

Thank you, Jon, for the flex steel idea. The lyre is definitely not the problem, checked already on that, I guess it must be the leg screws.

Since you could lift the action to look underneath, you can rule out
the stack binding on the pin block. My guess would be for a leg or
lyre screw had been replaced with one (or two) too long, protruding
into the key frame back where you can't see.

Also if the keybed is constructed with lowered panels, perhaps
something else is jamming. If the joints between glued beams
have a gap, a piece of wire or other item is also jammed.

Get under the frame with a long flex steel.
