Under the lid..
I've punched holes through the Weber shells with 100% success.
I've got a couple of tutorials floating around here somewhere.
The tape does not do anything but give you a substrate to mark your layout on.
The UniBit (aka "step bit") is your weapon of choice.
I have never punched a hole the size needed for the monster Weber therm port.
I think it is over an inch in diameter.
There are two other choices...
1) High temp silicone grommet from Grainger
2) Therm port from Cajun Bandit.
Both of those require MUCH smaller holes.
