fitting coping stone corners and retailers in the West Mids?

[coolas4k]

Hi,

Ive recently finished building and rendering my garden wall and i'm now ready to finish it off with some coping stones. I'm toying between flat or once weather coping stones but I have a query about how to cut/ fit the coping stones on a right angled corner. I have 2 corners to negotiate with the coping stone but as i've never done this before I would appreicate any help on the best ways to go about this? i.e. Do i cut the adjoining coping stones at a 45 degree angle each to butt together around the corner?

Also, where can i buy decent coping stones of this sort in the Wolverhampton West Midlands area or nearby please?

Yes mitre your coping stones at the corners otherwise you'll have a slope into the end of another stone.
I would have thought any reasonable BM would have the stones available, Selco, Travis Perkins, E H Smith, Buildbase, Jewsons, and many more.

I believe that internal and external corner copings are available for most profiles.
