Custom LEGO TRON: Legacy Action Stand


Hey everyone, Jason here. I picked up the TRON: Legacy set recently and it’s a pretty cool little set. It’s a bit pricey for
what you get, but there is no denying it is a visually stunning display piece, but
I was a little disappointed with the basic nature of the stand that came with
it. For me it just doesn’t evoke any sense of motion, which I think is a real
shame as that scene from the movie is pretty full of action. So I decided to
see if I could breathe a little bit more life into this model and this is what I
came up with. I actually built two identical stands and each has a
platform holding the light cycle that can move from side to side, and as they
do so, the light cycle tilts which I think gives a pretty cool sense of them
racing through the grid. I even added a little control arm at the back so that
you can get a little bit more of a hands-off kind of play experience. I
designed them to be independent so that you can pose them in different ways but
if you’d like to connect them together it’s easy to do, you can just remove some
of the tiles along the edges of the bases and then use them to connect them together. I also had to raise the light cycles off the ground to leave space for
the mechanism, which I will explain in a minute, and I think that actually adds a
little bit more substance to the display and it also kind of captures the
multi-level nature of the arena that they are racing in in the movie. If you
want to build these yourself you can find instructions over at
jkbrickworks.com. So how does the mechanism actually work. We’re gonna start with the light cycle mount and let’s just pretend that this orange
plate with two bricks on it is a light cycle. We’re going to mount this on top
of an axle like so which runs through a 2 by 2 plate with holes in it, and at the
end of that axle we’re going to add a Technic connector, which extends below so that we can use that as a control arm to control the tilt of the cycle. Now we’re
going to connect that plate to a shuttle, which has a pin underneath, which we can use to control the position of the cycle. So now we have two connection
points underneath the cycle which we can use to control the position and its tilt.
So how do we actually control those? If we look at the base, we have an axle
running through these Technic bricks mounted on a turntable, so that as we
rotate it from side to side this black pin and blue pin transcribe two arcs,
and since the blue pin is further away from the rotation point it will
transcribe a wider arc, which I’ve indicated with these tiles. The black pin travels about four studs and the blue pin travels about six studs. Now we’ll
put that shuttle where the black pin was and we’ll constrain it using these tiles. So that as I rotate that axle, it slides
from side to side. And now in theory we want to connect that blue pin to the connector that controls the tilt of the cycle. But due to the mechanical
constraints in the system we actually need a lot more degrees of freedom in
that connection point, so I’m gonna replace this axle with the blue pin with
this universal joint assembly, and now we can connect that tilt control arm there and we can reconnect the light cycle onto the top of the shuttle, and there we go. Because the tilt control point gets pushed out further than the shuttle position point, it causes the light cycle to tilt as it moves from side to side. and I think the result is pretty cool, it’s pretty compact mechanism that does a fair bit and that is about all there is to it. As always thanks for watching,
keep on building, and I will see you next time.
