Has the Italian restaurant Ai Pioppi that builds their own rides ever been posted in this topic? If not, here are the coasters from rcdb for you
Racing shuttle
The big shuttle looks really good for a home-made ride
Another shuttle coaster...
And bags of sand (aka launched coaster)

Apart from the unusual roller coaster the restaurant also has this weird ass flat ride, named Giro della Morte (or Wheel of Death if you translate it into English).
I'm planning a trip to this place next season (it's only a tad more than 2h of drive from where I live), does anybody wish to join me? I don't want to die alone
