In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction).

AN bolt question

I am ordering up AN bolts forvarious fittings throughout the plane. On the wings, we have some aluminum angle brackets that attach the butt ribs mounted over 4130 wing attachment fittings and using the same bolts for mounting. I have a feeling these should be stainless AN bolts instead of Cadmium plated for corrosion reasons. Is this correct? I am wondering if there is a need to isolate the aluminum from the 4130 with anything more than epoxy paint as well?
