Ramps and Teeter Boards

I’m not really into unicycling so I lent my unicycle and
The_Complete_Unicycle_Book to a friend. He has a couple questions about some
things he read:

  1. Does anyone have advice for building ramps and teeter boards (see-saws). What
    size and length board do you use. What kind of wood is strong enough? How
    high do you make the fulcrum? What is the ideal slope for these items? Any
    other information you can provide on making these items would be excellent,
    thank you.

  2. On page 84 of the above-mentioned book is a picture of an Astrowheel. Can
    someone please describe what this is, how this works, and explain where
    someone might be able to purchase one?

Thanks,
