Spent a night polishing.
In the meantime, he also inspected the bicycle, and there is currently no damage.
The seat has a major issue; he still doesn't understand how to produce springs, so he doesn't know how to install springs on the seat.
If he thinks about it, how should springs be produced?
He thinks a feasible method is to heat elastic wire until it's red and soft, then coil it around a cylinder and press it tight to form a spring.
He really wants to try it.
At 'Smarty Pants', they indeed can produce a type of elastic steel.
How to make steel wire from steel ingots?
By pulling a steel bar forcibly through a hole, it would be stretched into wire.
Spring wire doesn't need to be very thin.
He thinks it can be pulled after being heated until red.
Springs have many applications.
Not only used on bicycle seats.
He thinks the springs needed for bicycle seats must be very thick, strong, and sturdy.
Again, he is very tired from polishing.
