Re: "This" mouthpiece change dpes "that"

IMHO, It's hard for me to even believe that this fellow put up this video.

First of all, the baffle near the tip (and probably all the way down to the throat) is "not flat" but rather "slightly concave" going across the baffle. I just now cut out a thin, stiff piece of cardboard and placed it across the baffles near the tip of 2 mouthpieces that I have. One of them is a hard rubber Riffault I bought from sonicbang and the other is a cheap, plastic MSO from China. Both of them clearly showed the concavity across the baffle.

This is the reason refacers measure the tip opening "in the middle" of the mouthpiece and not at the edges.

So, what does this mean? To me it means that the reed is closer to the baffle at the edges than at the middle. Therefore the suction effect is greater at the edges than in the middle. It doesn't surprise me at all that the edges of the reed vibrated so vividly while nothing happened in the middle.
