The Merlin Engine

Heads and cylinders cast in unit?

Kind of puts the engine DM of "blown cylinder head gasket" into question, doesn't it?

They are still two piece.

Very cool vid OP, just shows us that the methods are still used today, it's in the design department the real evolution has happened.

Speaking of old machinery, the company I worked for back in the late '90s had a WW2 era lathe that was much used. Was used for drilling 3/4" dia holes in 6" dia aluminum round. Some of the holes went all the way through (up to 10" but the piece had to reversed) or tapping blind holes. No automatic reverse, so one had to be quick on the reverse lever. Can't remember it ever breaking down, though the newer lathe did.

I have a Czech lathe in my workshop, big ass chunk from the 50's, using it on everything from small bolts to 3.5m/2"+ propshafts and it's always smooth sailing. Old as heck but as I've been told, it has never never broke down in the 30+ years they've had it.
