Think about it, my steam engine can still be improved a bit.
First, the thickness of the iron plate can be changed to one centimeter; there's no need for it to be two centimeters.
After all, its strength is not even as good as a Dongfang tractor, so there's no need to be so afraid of it being blown apart by steam.
Secondly, he should try to grind off the excess parts of several cast iron pieces using a machine to reduce weight.
Once again, its manufacturing method should be redesigned.
He plans to first create a whole piece of cast iron and then drill pipelines from the side using a lathe, connecting different pipelines together.
The holes on the side are blocked with a designed iron piece and locked laterally with steel nails.
He believes the biggest challenge is in controlling the device for the valves of two airways.
He must cut off the airway and fill the gap with a metal sheet that can slide parallel, with holes in the middle, to either block or open the airway.
