I hadn't realised such things existed, I've always just put a second holesaw onto the standard arbor

The interweb is a wonderful thing Dave if you know what thing you are looking for is called. I only found it by looking at Starrett hole saws on Amazon and taking a closer look at accessories.

Stack two holesaws together on the same arbor

Well I be fecked that has to be the best bit of knowledge I have learnt in a long time and I will remember that for the rest of my career. I would never of thought of that and have struggled a few times before when I needed to open up a hole for a bigger diameter light fitting. Brilliant little trick.

All they need to invent now is a downlight with a decent connecting system that doesn't rely in those stupid incorporated screw down connect blocks! Still,I suppose thats part of the skill required to be a competent person!

The irony on this job is that the existing fittings are sat in 76mm holes so hole saw not needed! Still, on the plus saves a lot of work. Lesson - if dealing with proper customer rather than friend, do not rely on their measurements!
