A very simple question - but I have no experience of doing this ever. I
need to create a 4" diameter hole in an outside block built cavity wall for
a ventilation outlet. What is the best way to do this? Is there something
I can hire that would make it very quick and easy?
Either hire a core drill or stitch-drill a ring of holes and then use a
hammer and bolster.


Also I need to cit a similar hole in a plasterboard ceiling - I presume this
is dead easy - best to use a jigsaw?
Use a small handsaw, it's more controllable in plasterboard than an
(electric) jigsaw
