Busman's holiday. Decided to replace the electric fan in the kitchen window
today & typically the window pane (single glazed) cracked as I removed the
fan.

Popped down to local glass shoppe & got replacement pane of glass with a 6"
hole cut in it (how do they make that look so easy?).

Replaced the pane of glass & then found that the hole is very slightly too
small for the fan body - bugger. Glass shoppe now shut for weekend - double
bugger.

Since the glass is in place & SWMBO wants the fan working, any suggestions
on how to open out the hole slightly?

Altogether now..... angle grinder!!

I have a Dremel, various abrasive devices etc.

Who's a silly handyman then ;-) better to have the hole slightly oversize
rather than undersize,were glass is concerned anyway.

You measured the hole too small and then fitted the pane before trying the
fan in.

You've been watching me DIY haven't you!

You could try this....

Two pieces of thin plywood with the correct size hole cut out on
both,position the two pieces on either side of the glass hole and clamp them
slightly tight so as not to crack the glass.
Then use your dremel grinding tool to grind off the excess glass around the
hole level with the the plywood cutout hole.?

Dave,

I won't state the obvious. ;-) but with care, and using a Dremel type of
tool with the correct stone, it is possible to grind the edge of the glass
to the diameter required - but the odds are that you will break the stuff.

Try cutting a slightly larger diameter hole in a piece of 3/4" ply wood than
required by the fan, put that into a warm room and lay the glass flat on top
of it so that it is well supported (and the hole is over the hole in the
ply) and then carefully 'attack' the edge of the hole in the glass with the
abrasive stone - (damn, this reads just like and American workshop car
manual that I am having a look at).

There is no real secret to the job - other than confidence, having the glass
at a warm room temperature, well supported and taking your time. Oh, and an
extra pair of hands would be useful to stop the glass slipping about when
you are working on it.

All the best with this job.

Cheat. Use a bit of plywood and make do until Monday (or next
opportunity for doing it). Or if you have some suitable plastic sheet
material...

Do you have a tile cutting machine? The sort with a powered water
lubricated diamond wheel.

I you only need the hole to be bigger in a few places this will be the
easiest way. I have used one of these for this purpose but not to enlarge
a hole.

Shaving it off the fan housing (assuming it's plastic) I'm sure would be
the path of least resistance

About 2mm on the diameter, so 1mm on the radius.

But if you interfere with it and the glass breaks, no come-back.
Alternatively, be patient, take the glass back on Monday with a 6"
ruler and wave both under the bloke's nose.

Wave the fan under his nose, which is what I would have done in the

Have you done that before or are you just a genius? That works an absolute
treat, in under half an hour I had milled off enough to get the fan to slide
in.

It was only then that I realised the PCD for the fixings screws is larger
than 6"!

Finally - I read the instructions - it needs a 7" hole!

Why shouldn't he look in his wife's handbag - after all, his wife probably
does go through his pockets every time she launders his trousers or take his
suits to the cleaners - or metaphorically, everytime he has to pay for
something (if it's the typical woman, quite often I bet)!

==================================
I'd like to claim 'genius' but the truth is that I have tried it before
whilst experimenting with a home-made glass splashback. The method is OK
for fairly rough work but a good finish is best left to the professionals
even if it is expensive.

It would work provided the existing hole is bigger than the entire blade/
guard assy. It would be better to make a tedious series of very small
straight radial cuts of about 3-4mm over about half the circumference.
The cutts will need to be no more than about 1-2 mm apart.
The tiny fingers of glass that remains can be removed by very gentle
tapping/touching with any hard object.
