I do feel like a heretic tho. I would not drill this at all. I haven't used airlocks for YEARS

.. And never a spatula 😉

All I do is do the lid up and then turn it back ¼

Better still if the rubber seal is an o ring. Pull it out.
 
That's the plan. I was asking for advice on drilling the plastic lid. I didn't want it to split or break. Have you drilled plastic?
Loads of times. Easier to drill that wood or metal, but having reread this thread I wouldn't bother.

Try turn back ¼ now. Happy days.
 
Here it is.

I would just hang a 50mm length of string or thin copper wire over the lid, before closing. This will make a tiny gap, which is all you need.

I guess that bucket is about 10 litres?

Yes, 10 litres.
I was given it . The tap leaked on my first brew but insulation tape solved that issue.
I'm using a thin 6" wooden spatula to keep the lid slightly ajar.
My only concern about leaving a tiny gap is flies or dust getting in. An air lock gives me more sense of security.
Maybe I'm over concerned?
 
Many thanks for all contributions.
Today I plucked up the courage to drill the FV top and fit the grommet for the airlock.
I soaked it in hit water and used a small awl and the drills of greater sizes.
All went well, so thanks again.

I did hear somewhere about MELTING a hole in the lid with a bit of hot pipe.

This was a favourite trick when plumbing up a roof tank etc, heat up a piece of copper pipe of the right size with the blow lamp and push it through the tank ,quick and a neat hole which just needed de-burring on the inside .
