I need to cut a 150mm hole in 10mm marine ply, where the access is difficult.
I'd normally mark the circle and then use a drill to cut a series of holes just inside the marked circle, then use pad saw to joint the dots, finishing up with abrasive paper.
The location has very limited access from below, and constrained height above, so it's not possible to get normal drill in from above or below.
The hole is to allow me to fit a computer fan to extract hot air above a Victron 3kva inverter charger.
Any bright ideas?
