Here is the GBC ( great ball contraption ) that I have been
working on! It includes a conveyor belt
and a zigzag ramp section. The conveyor
belt lifts the balls up to a height of nearly eleven inches and can lift five
balls at a time. The balls then roll down
a series of six small ramps and one larger one. The balls are then picked up by the conveyor belt to start again. The six small ramps are identical in
construction and their side rail colors create a pattern of red, dark gray, and
light gray. The larger ramp has a black
side rail. The board that the ramps are
connected to is tan, but it also has a zigzag pattern of one by twos in blue,
orange, and yellow. The model uses a lot
of smooth tile pieces to give it a nice, smooth look. The only places where studs are actually
visible are on the base and the beam of the conveyor belt. This model is around eleven and a half inches
long, twelve and a half inches tall, and three and a half inches wide. The conveyor belt and zigzag ramps can easily
be separated from each other. The power
functions (which are an M-motor and technic battery box) can also come off
easily. You can also remove the light
gray gear (that is connected to the worm gear) and replace it with a hand crank,
to be able to manually rotate the conveyor belt if wanted.
The reason I built this GBC is because I thought it would be
a fun and challenging project. I think
this model would make a great Lego set because it is a very fun to watch when it
is going - and even when it is not, because of all of the colors that are on
it. This model is also great for any fan
of Lego, GBC, science and physics, or anything else that relates to these
