Then there is another issue, which is that a metal strip needs to connect the two hinges, forming the shape of a track.
What if we use another approach?
Can a metal rod in the middle of a single hinge be made particularly long, consistent with the width of the track?
Ma Lin thinks it's feasible.
Although it will consume a lot of raw materials, there will be many issues during polishing.
Consider the two-hinge approach again.
How can the metal strip be fixed to the cylinder?
The related process is a bit complicated.
Let's stick with the previous approach.
Are there any difficulties?
Polishing and installation might be a bit labor-intensive.
Ma Lin immediately starts making a sample.
Then he makes several more using the sand casting method.
In one morning, dozens can be produced.
Then speed up, using them collectively as a model for the sand casting method, producing dozens at a time.
It takes just over two days to cast all the needed parts.
