三つに分かれる線路はビー玉を正しく分けてくれますが、
小玉は線路の下をくぐるスペースがないので余分な隙間を創る必要があります。隙間ができたら、クニャ小道に小玉が流れます。
三つに分かれる線路から落ちる中玉の線路を作らないといけない。
三つに分かれる線路に円周螺旋は第三さんの外を回ります。 Large and medium marbles will roll around the entire track in a clockwise motion (as seen from the top), and small marbles will feed into the triple splitter from the other direction, though I don’t know exactly how far around the track they will go.
Right now くるりん is in the process of adding the first support that will hold up the Outer Spiral.
Though the stand-in Outer Spiral is a polygon of sorts, I plan to make the real spiral smoother somehow.
Next to the triple splitter, I have a very narrow space to allow the small marbles to go down to feed into the small marble resting area from the other direction off of the Little Wiggly Track.
(*) Though there are not currently any plans for an upper zig zag, I guess there might have to be one later in the construction.
Make a stand-in Outer Spiral. I originally tried to do large segments of the spiral with long bamboo sticks, but they split while being curved. I ended up using shorter bamboo skewers, which make it more of a polygon than a smooth spiral.
Make a triple splitter. The trickiest bit was getting the spacing correct. As of about August 2018, the spacing is correct.
Have the bearing fly in like a helicopter. This was done by suspending it from a broom handle mounted above the whole set.
Have the stage on a bearing. This allows me to easily reach the far side of the stage to pose the characters / glue stuff / etc while making the animation.
