Thanks again delphinus for all your quality input.
I am having the same troubles with mine-not a long enough collection chamber! I like your idea on the riser thing except that I think it may be too unbalenced as if I sneeze to hard my cup will fall off already.I have a nice quality brass air fitting that I'm gonna hook up and give a whirl.
Thanks again, Cheers sumfinfishe :D ;)
