How do you pull that initial vacuum?

And why?
I suspect he means PSIG. Some gages bother to mention it, some
don't...

But doesnt he start off with 14.6 +/- PSIG before he turns it on?

No, he starts at 0 PSIG, which is around 14.6 PSIA. His 125 PSIG also
equates to about 139.6 PSIA.

"Human nature is bad. Good is a human product*
A warped piece of wood must be steamed and forced
before it is made straight; a metal blade must be put to the whetstone
before it becomes sharp. Since the nature of people is bad, to become corrected
they must be taught by teachers and to be orderly they must acquire ritual
and moral principles."
