Uhhh read a wee bit more closely...."Gun Parts"....ooh, watch out,
they will be banning our torches soon.

Which gun were they making ? upper left of page 3 says "9mm Browning"

Same area says "oxygen 120-140 psi, acetylene at 13 psi"

That tells me they are near the upper limits.

Doesn't acetylene explode at 14psi?

The linked article said the person used a milling machine.

My OP was showing that a torch guided by a CAM can do very good
work, negating the need to much of the normal milling work.

Definitely NOT CAM. CAM stands for Computer Aided Manufacturing. WWII pre dates the computer by 2 decades.

Besides, Page 2 of the article clearly says "tracing head"

My question is how did they manage to get the tracer stylus to follow the pattern. My own tracer suffers from lack of adhesion between tracer stylus and pattern.....

It does ?

I dunno, the airco book I have that showed this machine calls the metal template that the magnetized roller runs against as a CAM.

You know, like the one in your car engine....

FWIW I have posted before, an old article showing a burning machine
run with paper tape, pre WW2.
