As mentioned in my Master Builder – Cars article in the NMRA Magazine, I created my own master to make a mold to use to cast frames for my “mini fleet” of On30 cars. One was cast in metal and the rest resin. I will have more info about a clinic I gave on casting posted in the coming months. See the other pages about how I used the frames to create unique cars that used the same frame so I would have a set of eight for use on my Inglenook I am building. More info about that too is coming!
