Again, totally makes sense..........but I was really hoping not to do that and opt for the old, 'bodge' job.....
You just need a mini grinder tool to do the job, should be able to rent one for a few quid, or if you are not confident ask a jobber to do the whole thing. As it's not a private road and you share it best to get your neighbours involved and opt for a proper job as scbk mentions.
