Which ones? I don't think SS are rated for carrying much, if any, structural load... Regards, Jay [quote="bhoppe2"]I had the same problem with the magnetometer mounted in my RV-10 tailcone using the SteinAir bracket. A cheap magnetic compass would swing when moved along the outside of the tailcone. At first, I presumed the AN bolts were magnetized, but they were not. I replaced them with SS bolts just to be safe. The rear seat shoulder harness cables were the problem. I demagnetized them with an old Radio Shack 100w soldering gun. I replaced the soldering tip with a 3-turn coil of 10 gauge wire and passed the cables through the hole in that makeshift coil. It worked like a charm. No more problems with the G3X compass. A friend recently tried to move his wet compass to the top of the windshield in his Cessna Skymaster, but he could not get it adjusted. We used that same soldering gun to demagnetize the overhead structure, but only using the side of the case of the soldering gun. It fixed his problem, too.[/quote] Read this topic online here: http://forums.matronics.com/viewtopic.php?p=459337#459337 ________________________________ Message 2 _____________________________________ Time: 01:29:57 PM PST US Subject: Re: RV10-List: Re: "Magnetic Anomaly" - Degauss rear seatbelt cables From: Kelly McMullen You can buy AN3C or AN4C bolts. I'd have to look up what the difference in shear and tension strengths is. I suspect that for shoulder belt anchor that is drilled through aluminum angle there isn't a big difference, and that is almost all in shear.
