I want to learn to thread brass rod and hold my cars together with nuts and washers like the real thing. I often use brads to reinforce wood joints and add nbws to conceal the brad heads.
A soon to be started project (when we get settled in our new home) is to convert some Lord Steamy 7/8 goods vans to reefers for the fictitious Sumter County Citrus Growers Cooperative. I was inspired seeing some Tropicana reefers nearby. Of course they’re refrigerator units while my cars will have ice hatches. The train (3 reefers, three flats with unknown as yet loads and a guards van) will be hauled by a black Fairymead with a leading truck, cow catcher, air pump and generator plus appropriate plumbing.
Also in the works is a passenger train behind my wife’s green Fairymead, a tram (Regner Willi) and passenger coaches for our granddaughter Jessica and a Decauville with coaches for our granddaughter Jennifer. Lots of sculpey passengers are in my future.
