This weekend I went to a buddy of mine's house who had never drilled a hole in his pot before. Everything was ordered pre-made (i.e. the ball valve in his kettle was drilled by the brew store). We fixed that this weekend. Both of us wound up installing sight glasses into our kettle. The installation went well for both of us. What you need to do this:
- Decent Drill (I've used both an old 12 volt and a new 18 volt drill)
- A Step bit that drills to your hole size.
- Bit oil (WD-40 works if you aren't drilling too many holes)
- Metal File/Sandpaper
- Plumber's tape (teflon tape)
- Sight Glass kit (I like both the midwest kit and bargain fittings)
Next you choose your spot to drill and begin drilling your hole. As you near the size of your plumbing slowly continue drilling to make sure you don't make your hole too big. Once you have drilled enough, clean up the hole with the file and sandpaper. Add plumbing tape to your fittings. Next hand tighten - you can leave it here or secure with a light wrench tightening (you don't want to strip your screws).
This was a fun addition and I can't wait to use it to measure my boil off rate!
