Unrelated, but I'd already get stuck at this step:
> I don't have a tool to make a big enough hole, but with a little research I find out a hole saw is the way to do it. It's an open-ended drum with serrated saw teeth that you mount on a drill to do the cutting. I go to my local hardware store, get some advice on what to get, and buy a 60mm hole saw.
Just the idea of buying a whole new machine for a single use, and not even knowing for sure whether it'll do the job, is already so demoralising that I'll usually just stop and hope that an alternative approach magically presents itself to my mind's eye.
Interestingly I don't usually have this problem when programming, but I really don't like DIY.
