Here are the instructions for fitting the manhole finisher:

Seriously - has anyone ever managed to put this theory into practice ??  To start with, the copper is not soft - it has been hardened by being whacked into shape… and as for being able to be “gently” knocked in order to bend the lip under - impossible - it just could not be done like that.

So I had to think of a plan B, and what I did was to cut the lip like this……

….and then attach the finisher while the cladding was off the boiler…..

….and it fits quite nicely…

Hi Milford

I and many other builders have successfully fitted the manhole surround. It just takes care and attention. Yes copper work hardens but when I for one was doing my fitting I just heated the copper with a hobby gas torch to soften it and carried on. The technique needed is simple and easily researched online.

Thanks very much Lynn - I have some experience of metalwork and annealing copper, but my concern was the temperature required would likely discolour the top surface due to conduction from the lip - so I decided on my Plan B

As always, my intention with posts is to help builders with observations and suggestions that can be of help - and in this instance, my suggestion would be to maybe make the instructions more comprehensive and mention that the copper will be work-hard and potentially require annealing in order that the “gentle” application of the hammer will be sufficient. Very Happy

I used your method to great effect and I am pleased with the result.
