The boiler and steam engine are both extremely heavy.
The iron pot, once filled with water, weighs a ton.
The steam engine also weighs a ton.
They would press the ground down.
Therefore, to place them, he specially hammered down a foundation, laid gravel, and placed many sleepers, so at least the ground wouldn't be deformed by the weight.
The steam engine's piston was fitted with a valve rod, which was connected to a linkage device to push a wheel. The wheel then used a linkage device to operate a blower.
This blower was very powerful; even four or five people found it difficult to move.
Ma Lin's current concern was the safety of this steam engine.
He was also worried that he had been too careless when designing it, overlooking some crucial problem.
As soon as he filled the boiler with water, a large crowd came to watch.
Ma Lin said, "Stand back, just in case something goes wrong."
He put on a safety helmet.
