Ian, of course this is also an option. I have thought of that I just dont have such a material here for the roof. Actually, for the mail coach in the picture above the chassis is from a commercial model thus it already has a weight. I will add 2 magnets on the floor of the body and I will use the metal weight of the chassis to adhere. If you have something that I could use, I dont know if Mike minds, but I would like to see it. If not in this topic in a separate about coachbuilding? It comes into mind I could use the metal from the tomato cans....
Mike again....most excellent and inspiring work!
Cheers
Andreas
