Fast and accurate way to cut plasterboard to match patress boxes - how
do *you* do it?
Is there a definitive method?
Tried a plasterboard saw (slow, not terribly accurate)
Tried a Fein multimaster with a tatty old blade in it (fast, can be
accurate, but too easy to overcut)
With care and patience, any method will be no problem - but I have a
lot of them to do, so it's worthwhile to find the *best* way.
I'd prefer to fix the patress boxes on the studs first, measure the
loose board with reasonable accuracy, take out a core in the board, in
approximately the right place with a holesaw, pull the cables through
the hole, fix the board, then trim the plasterboard to match the
patress box.
However, I could leave the cables loose, fix the board, cut the holes
for the patress boxes (using a template), pull the cables through,
then fix the patress boxes through the holes.
What works best?

Cutting plasterboard to a pencil line with an ordinary hand padsaw surely
isn't a problem? It doesn't have to be mm accurate as the fitting overlaps
the cut.

If you are in a hurry, dry lining backing boxes are the easiest type to
use - but I personally don't like them since they show behind the fitting
- and look very untidy with some of the newer 'flat plate' metal fittings
which stand proud of the wall with them.

yebbut if you fit 'em as intended *before* plastering they "disappear"
in the skim coat...
