Used some aluminum duct tape as a radiant barrier where applicable.  Aluminum plate to support the egg, bolted into shelf with SS bolts.  Finally a couple strips of brass with an air gap in the top hole.

With your background, I would have thought you would know better than to set up a galvanic cell with the SS bolts and aluminum plate, not to mention the brass strips and SS hardware.  😎

I thought about it, if that counts.  The aluminum is more anodic than the SS, so it will oxidize, but not fast as there are relatively low amounts of the SS and steel.   The steel screws will degrade on the brass first.  This will only happen when there’s moisture.  I can live with it.  I’ll probably be long gone when it falls apart.

I had the same thought. 😎
