There was a thread a couple of months ago about finding a stair gate to fit a rounded newel post and I wanted to know the outcome.
I have a similar problem - a rounded, rather decorative newel post in an Edwardian house.
Can't screw anything in to it and neither would I want to as it's a lovely dark wood and I think we would struggle to repair it if we had to drill holes in it.
So is Redmonkey out there or does anyone else have any ideas?
