Well, Streets, I had to hang on by my fingernails as I read up on those links, but I think I got it. That's all cool as hell, and whooda thunk........pistons and rods as shock absorbers.....torsional oscillation.....and "tuning" of chuncks I never thought possible!

Hope you're not planning on quitting this forum any time soon. We need guys like you to assist us "ignerent" types....

Thanks again! Gotta go make more love to my FERD now.....
