Hi all-
I am curious if anyone has experience or can point me to a link regarding the use of aluminum washers (and possibly nuts, bolts? in non-structural areas) as a means of saving some weight. This topic has been discussed on VAF in terms of torque values when mixing AL and FE hardware, but I'm curious if anyone has used, say, AL washers when assembling the wing spar, etc. Regarding galvanic corrosion, forum discussions seem to indicate this is not a particular problem, and the washers could always be given a shot of primer if that was a concern. Is this worth looking into? My bag of steel washers is pretty heavy...
