Just for the record !
*
Remember this single-lp-adapter ? A downsized version of it, for example made by 3D-printing, could also turn a wedding band reversibly into a spinning top. The sphere acting as a the tip would be glued into the central hole. Even some balancing is possible by moving tiny weights along the (three) spokes. Would this lead to a new
world record in spinning time?
Or go the other way: take one of these original adapters off the
record and construct a flywheel that fits to it. Into the central hole you can stick something like a short piece of a ball pen that works as stem and as the tip of the top at the same time.
Just for the record: everybody is invited to put these ideas to the test by actually building these type of tops. I will never claim that my ideas were used without my consent.
* the look of some of these adapters remind be of the profile pic of "Aerobie". Before I joined this forum and just browsed around here, Aerobie often showed up when I searched for subjects that are of interest to me. It seemed especially Aerobie could have similar goals here as I do. But now I see he was not active in the last 2 1/2 years. Any body knows what happened? Did he lose interest in the topic? Maybe he just reached all the goals in the field. I checked a bit more and found out that Alan Adler really was the inventor of that special boomerang! Well, some 30 years ago I had one of those and enjoyed playing with it. Probably ended up hanging in some tree. That is the biggest draw back in constructing a boomerang that way: it likes to get picked up by branches.
