When we build scenery on modules for public display we have to decide if motor vehicles will be glued down permanently or just set on the module. I like to have as many as possible not glued down so I can set them up differently at each setup. The problem is that when the module gets bumped, the vehicles slide around into unrealistic positions. With this module I wanted to try something different.
My first thought was that I could just place small pieces of metal under my vehicles but because the base of the highway is 1/2 inch thick plywood the magnetic pull was not strong enough. I wish I had used some thinner material for the base of the highway instead of using the section I had cut from the base.
So plan B was to use the same magnets in or under the vehicles. Mostly trucks and buses will be displayed on this highway so space for the magnets should not be too much problem but because it is going to be magnet to magnet the polarity of the magnets will need to be tested for attraction before installation.
