Given my weird sense of humor, using hockey pucks ala Mark Wendt's comment sounds cool, but geez I'd have to *buy* some. I can find stuff in my scrap box to cobble up dampers like yours. When I was a boy I loved the Walt Disney movie "So Dear to My Heart". In it a wise old owl sings about how "it's what you do with what you've got". You have a knack for doing a lot with what you've got. Regards, Kent PS - getting further off topic, I got goosebumps when I saw "4CX5000s". There was a time in my life when Eimac was my favorite brand. We real men used to read by the glow of the filaments in the big bottles in our finals. Ceramics ruined that for us. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
