This type of track has never been made before.
So others don't know how to do it.
Ma Lin had to do it himself.
Lots of components.
Can the track function without using metal?
Can rubber be used?
Rubber easily deforms.
And then it's easy for gaps to appear, allowing straw to get stuck.
No one considered this issue before.
Their rubber production technology is really poor.
It's even harder to produce thick, large, complete pieces of rubber.
How is the track made?
A mechanism similar to a bicycle chain, with a long metal piece attached to each section, allowing relative rotation between sections.
Thinking about it, the production process is very troublesome.
They are incapable of mass-producing metal parts.
They are all handcrafted, and even if it's the same part, no two are alike.
A single track requires many parts.
Isn't it a headache?
Yes.
Start making it quickly.
Two bicycle hinges need to be made.
Each one is quite long.
The two must be made to high standards.
