does anybody know how to port reed cages on banshee

pm 370banshee or eviltwin

i know how....

how?>>>>>>>>>

I have done a couple sets

just port match the cages to the petals..

i have read about this before.i think in graham bells book.not sure but i think you need atleast 1 or 2 mm for the petals to seal properly.other than that the bridges are knifed.make it flow.

Anyone got before and after pics?

I'd think it'd be a bad thing to screw up and go too far so the petal goes through right?

does any one have and pictures... when doing this what do you take off... do u just make it aerodynamic or what... make a better sealing surface for the reeds???
