It's working!
24th April 1574
At first, nothing happened.
But well, that was only to be expected. Starting the fires meant that the water would slowly heat up, only reaching the point of bursting into steam when we would hear the metal of boiler whining under the constant barrage of the inner pressure, signalling that we could finally start the first tests on the engine.
With how there were two valves that operated the supply of both the hot steam and the cold water, we had to figure out the ratios at which they should be turned on and off to connect it with the swinging movement of the balancing beam as to allow this entire machine to work without any other human help than supplying more fuel into its furnace!
