As every wargamer knows, the little lead things just seem to multiply, courtesy of some very obliging manufacturers. And these interwebs things just make things worse. So I tackled the problem by nipping down to the local hardware store, picking up some big pine boards, some edging strip, 4 castors, and having a chat to a mate who works in sheet metal.. et voila! (much sweat and cursing later) I have a rolling storage cabinet. Magnabases grip the steel sheets which slide in and out as required for transport. Now I just need to build another three of these..
