The last time I did it I trimmed the cork to length with a scarf joint, soaked the cork for a while in very hot water and then fitted it in the groove and left it overnight cork side down on a flat surface with a heavy weight on top. I found the cork compresses and conforms to the shape of the groove in the cover quite nicely, and the pressure onto a flat surface ensures the cork presents a nice straight sealing surface. Must admit I have now invested in the new silicon jobs for next time.
