I'm installing around x10 (Aurora - 12v - fire protected) Downlights in
my Kitchen's plasterboard ceiling.

The plasterboard's hole cut out diameter is going to be 85 mm for each
downlight - what is the best way to make these cut outs?
I have a fly-cutter with a big dish under it that catches all the
rubbish. Unlike a hole saw, you can set the diameter to exactly what you
want. However, fly cutters in power tools are potentially quite
dangerous. If you are only cutting plasterboard, a hand drill will be
adequate and will give you more control over the cut.

Really, Ive done them with a 'kitchen devil' knife.

They don't have to even be neat. the fitting covers well....

There we have a basic difference in philosophjy. I don't think that
something not being visible is a reason not to do it neatly.

Agreed, but its a definite reason not to get ultra prissy about it.

Are you the sort of man who goes over the building site before the
suspended floors go in, with a black bag, picking up all the half
bricks, screws and mortar blobs, and getting the lads to sweep the soil
clean and level it with a whacker?

Sorry, I don't like a mess either, but the only layer that gets the
perfection treatment is decoration..and visible joinery.


Structure is structure, and its not there to look pretty, its there to
hold the important stuff up.
