Three type of nodes for the structure of the main slope
This node is the one asking for the lowest quantity of
wood (contrary of the two others) but the ramp is
supported on the edge line (of the prominent wood) and not
on the flat part of the bar sections. There's, there for, a gap
between the two wooden timbers.
Because of the gap's problem, we added a second
vertical placed in a staggered pattern to better support the bar
used for the slope.
