The cork absorbs the shock of metal hitting metal. The weight 'cushes' rather than crashes when it contacts the pressure plate. EmperorZurg perhaps could add specifics from his design notes.
@Nature, many thanks for re-posting the pics, pixel by pixel.
@BryGuySC, I've been schnooking around with Chrome for months and your solution sounds like it may have legs, thank you. I'll test it later and if it does then you guys may, by the number of pics posted, come to regret Bryan's sage advice. What do you do in IT?
@EmperorZurg, thanks for the advice with Gmail/Chrome. I emailed myself an image from my tablet, opened it and dragged and dropped (because Chrome doesn't play nice with Copy/Paste).
Altogether I suspect that you guys provided a solution all around, from the problem at hand, to the reasons why and the ongoing solution. Impressive.
