Those HD magnets are STRONG!! I have a few that secure various things to my metal storage cabinet in the garage!! Never thought of your idea Greg. You ever think of sending it in to 'Ideas that work' at EC mag?
Back in the days, I use a wad of string down, and a short piece of fish tape & wasted a lot of time ccasionally.
BTW, did you think of making a 'small' pilot hole to assist in locating your missing NMC?
