Overshoot -- Pitch Raising

[Don]

Hi Del,

What I have noticed is that Baldwin Hamiltons require a tiny bit of extra
over pull to end up dead on A-440 using Reyburn Cyber Tuner. This is
another indicator that plate flex (or hitch pin bend) may have more to do
with overcompensation than the soundboard. As the pitch change increases
this seems to become less of a factor, as you can infer from the table below.

This same need for extra compensation shows up in lowering the pitch on the
Baldwin Hamiltons.

data:

pitch	pitch	final
change	worst 	pitch

50		100		+1.2
50		100		+1.6

20		60		+2.1
3.4		13		+0.8
8		26		-1.3
2.7		na		-0.2
