Just build it and it will be fine. You probably only need maybe 20 or 30 db of attenuation really. Also, I would recommend the Cauer filter. It will do the job with a lower order and fewer parts.

Subject: [softrock40] homemade chebyshev 7th order BB band stop to begin soon
What parts I didn't have are on the way to start construction of the
chebyshev 7th order BB band stop filter. The inductors will be a
combination of ferrite and powdered iron toroids. I'll be using the
ugly duckling or island method to make this and then placing the board
into a metal casing. Since I haven't done anything like this in a
while, I wonder how compact I can get with the toroids, should there be
a certain spacing, orientation, etc? Thanks.
Jon
