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.
