I think that the only reason people make them solid, or at least why I make mine solid, is that I dont know how large the wave lengths will be,...and it is usually easier to find solid metal containers

You're right HL.

I was trying to point out that its more important to ensure that the whole of a gun cabinet is electrically bonded together ( especially the door), than it is to tape over any screw fixing holes with aluminium foil which will have no / minimal effec.

A metal dustbin with metal lid electrically bonded to the base would work equally well, maybe better than gin cabinet.
