I suppose if your nutplates have been stuck to a magnet for a while they might cause some compass error within 3 or 4 inches of your mag compass, so don't use a magnetic pickup to get nutplates out of the parts drawer. Tom, Interesting tests. I have a vertical card compass mounted to the glare shield to keep it as far away from electrical influence as possible. A SS screw placed near the compass is a problem since most of my screw drivers are magnetized. So far I have been lucky in not damaging any sensitive pivots in the compass by not using the heavily magnetized drivers whilst screwing. Card compass damage from this mistreatment is well known while there is no such effect on liquid filled compasses. Drat, so many little things that can do ya in...................
