You must adjust the compass with a "Diddle stick" a plastic on non-ferrous object. The adjustments consider the metal in and around the compass. There is perhaps much more iron and steel in the instrument panel area with throttle and mixture cables, some handles for fuel and dump valves etc. This action is important in "Rag and Tube aircraft where there is a much greater amount of iron and steel in the structure. Considering our craft are composites the amount of steel in blind nuts seems insignificant. Bob Smiley
