How do I go about modifying my brew kettle and adding things like a thermometer and ball valve?

7/8" step drill bit for starters.

Then you will need your hardware, here are some examples:

These are all great tips! Make sure when you install a thermometer you position it at the proper height. Too high on the kettle add you won't get readings when the liquid drops below the probe; too low and you risk damage to the thermometer from excessive heat produced by the burner.
