Hello,
how to move a pinball machine down a rounded staircase? It's only one floor, and the stairs are circular (see picture taken from web - the real one is less steep and bit wider). The staircase is quite wide, but not enough to keep the machine in orizontal position, so to it's needed to keep it in vertical position
How to move the machine in this way? Are some tools needed?
