I need to cut an elliptical hole for a 32mm waste pipe to pass through a wooden wall panel at a 45 degree angle - does anyone know, is this doable with a holesaw and an in situ jig (ie some bits of wood)? Is there an established method for this?
Or should I just cut slightly larger round holes and fill the gaps?
A hole saw will not likely be deep enough but if you made a jig, you could go at it from both sides to cut two edges then stitch drill and/or use a hacksaw blade to cut the rest?
I used a drill extender and holesaw bit to get through a stud wall and then the soil pipe. You can use a laser to work out the centre of the hole (ours was at a weird angle).
