Wrong. Manual lathe work beyond simple turning of parts requires considerable math skills. For example, thread cutting requires being able to grind you cutting tools precisely, setting the speed of the feed and rotation so that the threads are cut at the proper angle and distance as the tool moves down the work. Cutting radii requires special tooling and set ups. Finish on the part requires an understanding of cutting tool shapes, feed and rotation speeds, to get the proper cut for that finish.
It also requires understanding metallurgy to a degree as you have to know how the metal you are working with acts under various conditions. Turning brass is different than bronze, and steels vary widely by grade as to how they act. Aluminum is different too.
In my case, that would be a very bad bet on your part. I'd bet RB can create drawings particularly working drawings as that's usually something the machine operator does as part of their job.
You've obviously never done machine work. NC and CNC machines require programming and math skills on the part of the operator. Manual machining with or without DRO require understanding how to set up the work. Bet you have no idea what that's for or the math needed to use it.
Are you suggesting that you have a monopoly when it comes to working with a lathe???????????????????
