This will be my 1st time putting plasterboard on ceiling and I have to
fit around the pipe stack. My main concern is if I measure too
accurately and maybe a couple of mm oversize it would be a pain to try
and trim 2mm off the plasterboard.
Whats the experience of others when measuring this, is it best to plan a
slight undersize and then fill in at the edges? or triple check the
measurements? or both?

A small surform plane is just the trick for trimming plasterboard down, e.g.

Any sort of wood rasp, in fact. The most difficult part of the job is
lifting and placing the sheets. If you have tried to be too clever in
fitting neatly, it will get stuck and you may break your nice cutout.
You can go about a centimetre oversize and still fill neatly afterwards.
Do you mean a soil stack?

Yes it is a soil stack.
I have a small surform plane last used 20 years ago :-) I only
rediscovered it a couple of weeks back.

you can rasp the oversize bits away.

In any case you don't want to fit too close to the pipe - need a bit of
expeansion joint


leave 4-5mm gap and seal with decorators caulk.

Interesting idea, but are those measurements really correct? The prop
is room height plus 50mm plus the depth of the cross piece, plus the
thickness of the board? Will that really spring into place?

2x1 is fairly bendy and it will still work at a slight angle, especially
if the floor isn't too slippery. The one thing you don't want is it
being just too short.

Yup, the 2x1 at that length is fairly springy. Just lift the board and
shove the prop under it (in fact you can lift the board using the prop
partly - a gentle kick will wedge it lightly in place. You can then
reposition the sheet as required and spring the prop in more firmly when
you are happy with the position.

Sorry chaps! For some reason, I had read the upright as 2 x 2 and
couldn't imagine it having enough flexibility. 2 x 1 makes perfect
sense :-)
