degaussing for compass
SOMEWHERE on the net I've seen somebody who rents out equipment to degauss
the area around where the compass goes. In Cessna 180/185s the compass rests between a steel "V" brace and this sometimes gets a magnetic set, or something. Does anyone remember who rents out that equipment? Karl "Curator" N185KG |

Didn't Mike Pickett know someone who has something like that? |

Sacramento Sky Ranch used to rent a degausser, or you can buy one at
Radio Shack (it's called a bulk tape eraser). karl gruber wrote: SOMEWHERE on the net I've seen somebody who rents out equipment to degauss the area around where the compass goes.

Be aware that a "degausser" can also be a "gausser", and magnetize the object instead. It may be a more tricky task than it appears, since to degauss the object one has to apply exactly the amount of magnetism of opposite polarity. When erasing tapes, this isn't much of an issue, because the recording process will overcome the relatively weak magnetism. I'm not so sure about successfully degaussing steel bars near a compass, and certainly not while they're installed. Neil |

degaussing for compass
Degaussing an airframe is not quite the same as degaussing a magnetic
tape or CRT. I have "heard" of people doing it with a 110VAC line and a 100W light bulb for a load. |

It may be a more tricky task than it appears, since to
degauss the object one has to apply exactly? Degaussers work from line power by generating a strong 60 Hz alternating flux which is slowly decreased in intensity by removing the degausser coil away from the subject. I'd remove the compass and any electronics first though for that reason. I'd think a strong or larger degausser could be temporarily made from a 500 ft coil of three conductor (plus ground) # 14 romex wiring cable. The ends should be connected to make a 2000 ft coil, and the whole mess tied together with tie wraps. As an alternate the whole mess could be made with 3 conductor extension cords. & a suicide plug/socket arrangement. Has anyone ever tried something like this? Neil |

Is degaussing an airplane considered by the FAA as something that an owner/pilot could do? Jose -- "There are 3 secrets to the perfect landing.
