After all you've wrote about cork on the UJ and leather pad installation earlier now you are giving advice on rounding off the edge of the pad? You've got to be kidding?

In many cases, a cork pad, once again because it is of necessity smaller in diameter than a bladder pad, is sealing very close to the edge of the pad, so there is no room to carry out the ideal of rounding the edge of the pad. As I mentioned, a frustum shape can be used for a register key, but that is only because the vent is much smaller in diameter than the inside diameter of the key cup". **** < http://test.woodwind.org/clarinet/BBoard/read.html?f=1&i=221244&t=221154

I hope you finally got it? LOL
