Hi,
I'm new to all this!! I am in the process of putting some decking down and I have purchased some walkover lights to go in the floor. Most people cut an 80mm hole for these lights and whack them in, but my decking has ridges in it. The ridges are only about 3mm, the lights are 88mm so there's a slight flange but I would like to rebate the light to give it a professional finish. Summary the hole for the lights needs to be 80mm then I need to rebate the outer measurement (88m). My brother has a router that he's never used which he said I can borrow. How should I proceed, there's 6 lights i'm putting in so i'm looking for the best method – is the router the best thing to use?
