I think, probably, that the use of carbide just wasn't necessary in a
shop where we usually made only one of an item or care how long a job
took... within reason.


I mentioned hanging around the machine shop when I first worked as an
engineer. One of my first questions for the machinist running a very
large lathe was, "How do you choose the speed and feed?"

His answer: "I just set them nice and slow. If a supervisor asks me why
I can't do it faster, I just tell him this is as fast as this material
can be cut. That way I get to relax a lot while it's cutting."

Obviously, the guy's pay wasn't tied to the number of pieces completed.


When I was stationed at Edwards AFB I was in the F-111B test program
but was assigned to the base machine shop when not actually required
in the detachment. They were still using a large "plainer" which was
installed about three feet from one wall and the operator ran it from
the wall side. He had a chair and used to read a book while the
machine was cutting. I once accused him of setting the cutting speed
by the page, rather then FPM and he just sort of smiled.

But in that shop (all civilian except for me) the shop manager
encouraged the machinists to work slowly as the resulting "backlog"
was ammunition for him to request more employees and more employees
meant that he would be promoted to a higher pay level.
