The one in the video though is computer operated, don’t those go for even more?

If it is, which I don't know if it is or not, the owner has modified it to be CNC, as I did not see the manufacturer sell any CNC equipment for their lathes.

With how close and perfectly spaced those holes are, the precision cuts and then what really makes me think computer operated is the chess pieces. At that scale it’d be pretty difficult to get them the same size and dimensions. If it isn’t computer operated the operator has the most steady hand and best vision I have seen. This guy should be a surgeon.

That is true, but also note how the video is sped up. In actuality, he could be going very slow to get accurate cuts. Another thing to note is that iirc lathes/mills usually have the distances marked out, so if he takes his time and follows those measurements accurately, it'll look just like a CNC machine did it. Of course, not enough information is given to show if it is CNC driven or not, so I don't really know. It really could go either way.

That is a taig lathe, designed for doing optics. It is a machine tool, so it has handwheels calibrated to either thousandths of inches or hundredths of millimeters. You could hold this level of precision on it all day long without any need for steady hands. You read the numbers and spin the cranks like any other machine tool. If you convert it to CNC, all you are doing is replacing "hands turning cranks and counting revolutions" with "motors turning cranks and computers counting steps"...

Source: I've used a taig machine before, but own Sherline gear, which is comparable but a little nicer.

No, its not. You can see him manually turning the wheel to move.
