i purchased from Korber via eBay a 3-stall unit. Finally, after using every profane word I could think of I got it together. This is a model #320, which may no longer be produced. There were no directions for attaching the doors other than “...attach the doors “. Note photo of door frame which shows 3 hinge slots on door frame. Note also pic of a door pair with 3 hinge-like doodads on each door. I have no idea how these are to be attached. I emailed Korber and got a quick response. Unfortunately, the response was simply that Korber roundhouse doors do not open and close; no response on how to attach them. Next, I got the idea to search for O scale door hinges - found them on Altoona Hobby Works. Described as suitable for roundhouse and other industrial building. But no description on assembly or pic of a set installed. Photos of roundhouse and other buildings on their site are too low resolution to be of use (same on Korber site). I did buy the hinge package which included 8 strap thingies, 5 tuning fork shaped devices, and 9 apparent hinge pins. Website description does not include how many doors are provided for. Emailed Altoona for help about two weeks ago. No response so far. Perhaps they were busy preparing for York.
i can certainly take a nipper and cut off the vertical part on the door (those do not appear to be sprues) and trial fit the remaining straight section to the frame slot and glue in place. But I thought brass door hinges would add a nice touch.
Constructive comments will be appreciated.
