I'm currently building a functional LEGO escalator that is minifigure-scaled and with staircases transitioning from flat platform to stairwell to flat platform. Here's my progress so far: Here's the stair design I use for this escalator:
Now that I have clearly defined the necessary framework for the slope, I am currently working on the escalator's flat top (yellow). However, I couldn't come up with any designs for getting the flat top to "connect" to the slope without any ridges or gaps that could catch the stair's shafts.
Ideally, this build should utilize legal techniques for ensuring stability due to its technic nature.
Bricklink and any Pick-A-Brick retailers of similar fashion are not locally available for me, and I don't have the necessary bricks at my disposal, so therefore I couldn't physically test out my builds.
