Finally I was able to install three of the stars. With a lot of lifting power from Lars, Jonas and two guys from Hansa Bygg, we got them in place. The kids at the day care center went crazy when they finally got to climb the stars, when i left after securing the stars to the foundations there were two to three kids on every star.
Jonas and Lars look pleased and they should be, actually it took four guys lifting to get the stars in place. Thank you guys for the help!
