[pianotech] Shank questions

[J Patrick Draine]

Ed,
I think Mark may be referring to the WNG shanks' becoming very flexible
(much more pliable than wood) when heat is applied to them for the purpose
of twisting shanks (aligning hammers which need to have their angles
corrected). My understanding is they are then quite stable when returned to
room temperature. But, that's more my absorption of the party line of
M&H/WNG, near neighbors in Haverhill, MA, than experience.
