Building lathe/mill in cast of concrete?

Yes you can make almost anything out of concrete. The moulds for the Mosquito fuselages were made of it. The Mulberries were, some yachts still are and all of the tracks in the Paris underground –the Metro- still are. The trains have rubber tires which run on steel plates bolted to the concrete track way. The stations stink of hot rubber.

I once worked in a factory which built machines. Each time a new machine was started its concrete building base was ground dead flat before the machine was started.

The Hoover dam was built in rectangular blocks because a single pour would have taken 125 years to harden.

Yes they used much concrete as we built two. These were full sized harbours each able to support and supply armies.

One was for the Brits and the other was for the U.S. of A. Unfortunately one of them was a total loss after the first really good Atlantic storm, so the second one had to carry the whole load. This ‘bottle neck’ which led to supply shortages, and caused a slowing down of the war in Western Europe. as it gave the enemy time to consolidate. The remains of the second one are still there to this day (nearly 70 years later)

Which one was lost and why? A few clues, which lot did not bother to train the builders? Who placed a senior officer, who could not read engineering drawings, in charge and who threw away the instruction manuals? If the designers/builders give you 24 anchors each with two wires attached do they mean you to use them all? And finally who just took the bits and pieces higgledy-piggeldy (for speed) and not in the order they were laid out. You guess who.
