The world's first "railway" locomotive
The person who is impressive in The manga biography of the great in the world read when I was a schoolchild is Edison and Lincoln and Watt.
Watt is an inventor of a steam engine.
I was charmed by the picture of the very mechanical steam engine.
The time of the Industrial Revolution.
I like appearance mechanical to that futility very much.
A present-day machine is theoretical and too minute.
To be sure, a function is wonderful.
However, the amateur cannot treat.
A TV program called a robo-con(robot contest) is broadcast in Japan every year.
The student of an industrial high school makes the robot of an independence walk, and makes it fight.
I am impressed by it.
However, I do not think wanting to make a robot.
It is because an understanding is impossible.
I like a rough thing.
When out of condition, it will be repaired if it strikes.
Back to the subject.Watt invented the steam engine.
However, there is an eccentric person who attached the wheel to it.
The peculiar British is Trevithick.
He is just an inventor of a world's first steam locomotive.
He made the trial production in 1801. Trial and error were repeated. And it was completed at last in 1804.
The locomotive picked up 10t of iron, and 70 passengers, and ran the whole distance of 16km distance.
However, it took 4 hours.
The papermodel which I made this time is this steam locomotive.
Especially I put power into the mechanism.
In short, I like the gear.
This gear is a movable type.
Spur gears
It is not strong if there is little paper to be used.
Various methods can be considered.
However, under the present circumstances, this method is the best.
Since it is paper, there is a limit in making small.
A module 2 will be the minimum. Skillful work is needed less than it.
frame
Various forms can be made if usage is changed.
CD stand,book stand,stationary stand,etc (stand stand stand)
This has effective application.
I want to exhibit this item in the future.
The stick was used for the axle.
It is impossible to make this from paper.
Then, various items are omitted···
Completion picture
I am impressed by the lump of such a gear having run in the town those days.
The flywheel side is slightly insipid.
I thought that this was a front when I also actually look at a photograph for the first time.
Running steam locomotive. However, it is pushing by hand.
Rotation of gears.
A motion of a crank is also interesting although it is simple.
