that looks really good I would like to see the filter you are going to use. Did you use the original piece that held the filter in place and just cut it out? or fabricate a new one. Very interesting some of the enginuity on here.

I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago. Edgar Allan Poe
