Re: [Harp-L] Thicker reed plates

[Vern <jevern@xxxxxxx>]

In practice, donât expect any perceptible differences in the range 1-2 mm..

In theory, thicker plates should absorb a bit less vibrational energy, making the reed a tiny bit more responsive.

By keeping the air flow shut off a little longer as the reed passes through the slot, there is a small change in the audio wave form.

I canât tell any difference in 270 (1mm) plates and my 64X (doubled  1 mm x 2) plates. The effects are minuscule.

I conclude that 1mm of brass is thick enough.  Twice as thick is still thick enough.  A less dense metal such as aluminum would require more thickness to have the same mass near the rivet as brass. Plates thinner than 1mm might make a perceptible difference.
