The Egyptians were masters of one part machines.
I can imagine "easier" and more robust machines to accomplish the same function but they all require modern materials and/ or additional parts.
If they really did think differently as I propose then their ability to imagine and invent complex machines was extremely limited. We can reason backward from what task we want a machine to accomplish to what design it must have to do it. They couldn't.
The fire-pan merely sat on water and burned a thin coat of oil on top. When it quit rocking it burned out because it wasn't being refueled and the men knew there was no need to report to work. There would have been various operations going on at night and the pre-dawn period that would be affected by whether there was water flow or not. They never worked on the pyramid at night but they certainly had operations related to building like preparing for the work day, bringing ships into the harbor valley temple, watches, and sealing cracks and leaks;

There was extensive work to set up for the building crews which employed many dozens of men. They had to check supplies and provide meals. Perform sanitary work and make sure all the tools were in good order and at hand.
Unfortunately there are no other utterances specifying all this work but this is only natural since they didn't work at night and said this many times. They compared working at night to walking upside down! They didn't do it so there simply weren't any ceremonies at night so no night time ritual appear in the PT.
This fire pan (mks-sceptre) was simply a machine with one moving part and that part was driven by the waves on the water. I find it ironic that this device became the origin of the word "god" in modern languages and that "god" is the light.
