[Harp-L] Re: Waxing Rivets for Overbends [oops!]

I meant to include a link in my earlier post, but skipped it when my server
developed problems and then forgot to include it.

Here it is now... As I wrote [plus link]:

Additionally, though, here is the website's explanation of their movie image:

[For example in WinAmp, click Toggle Repeat to loop the short movie.]

=====================================================

In this example, it's shown affecting a plate-shaped object [more harmonica
reed shaped] in the air stream.  More akin to a harmonica reed shape, I
figure.

Interesting to me is that the induced vibration of the "plate" seems to be
crosswise... from one side to the other, not in typical reed fashion as we
think of it as being lengthwise, waving up and down.

Anyway... Sorry about the mixup and delay.  My bad.
