How do you know you haven't ruptured the hermetic seal.
You have three vary intelligent engineers telling you that
you've done something wrong. You answer that with a statement
that it didn't seem to have done any harm.
One wonders why you come to this bulletin board for advice
and then as a show of foolishness, choose to ignore that
advice.
If you were working in my department, you would have received
your first warning.
Let us hope that you don't someday create a design that people's
lives might depend on.
Dwight
