To cut the 85mm diameter holes (or 3.346” in old money), go out & buy a hole cutter if you don’t already have one. The cutter I used is what I have always known as a ‘trepanning’ tool – they call them ‘Tank Cutters’ nowadays in the UK. It is infinitely adjustable and can be used for all sorts of other stuff. It cost about £8, so it won’t break the bank and gives not a bad finish with a little tweaking here and there. A hole saw gives the best cut; however, I couldn’t get one anywhere in 85mm. A couple of medium / fine flap wheels are needed, both for finishing off the edges (although I used files and wet & dry paper) and for doing the brushed satin finish.
