in the model train scratching and bashing section I have a thread called time to build Union Station. I cut window and door shapes out of plastic, and then made moulds and resin copies for the build with one of the resid casting kits from Hobby Lobby. I have a bunch of HOn3 ore cars I want to make, and likely that will be done with resin. I have scratchbuilt four out of wood, and have wood cut for another four. I eventually want to make a boat load of them, so one of the wooden cars will likely be sued to make a form for a rubber mould for mass producing them from resin.
