"Fish"....my best guess... ( saw Terry's lovely photo )

Read Ron Overs posting just a couple of posts ago (More CC
questions....)  It describes the purpose of the cut-off and the fish
very well.  Basically, you're making a tweeter.

is that it stiffens this area of the rim so that
vibrations travelling from the board are not creating
friction, and lost as heat energy (  due to molecular 
"wiggling"  )  but are more likely kicked, or
otherwise ransmitted,  back into the board. Right ?
