I always wanted a roundhouse. I scratch built an automated turntable years ago and have always used it but getting around to building a roundhouse was on my list. Found the Korber 3 stall kit and bought 3 of them. Since my layout was already established I had to make the Korber fit the the tracks in place and the space available. Needless to say this was a massive kit bashing project. I made 2 of the 3 stall units and one 5 stall. All of them are somewhat shorter than the kit so a lot of cutting and modifying was in order. The doors, well that was another matter. Since I have a 3 D printer I designed and printed hinges. Then I designed and built automatic openers for the doors. The doors are controlled by an arduino and a stepping motor for each door. When I select the track to use the automatic turntable system, controlled by an SMINI and JMRI produced an output that the turntable uses to activate and index. I used that signal to to control the automated doors. I also 3 D printed LED light fixtures and junction boxes and receptacles and wall switches and installed wiring on each wood frame. Those also are controlled automatically based on the stall selected. I have spent about 5 months part time working on this and now have everything working and installed with the exception of install the roofs. I spent hours cutting and grinding and filing the kits red castings. That was a major pain. On a scale of 1 to 10 I would rate this kit a 15 for difficulty. I am happy with the result but boy was it a project.
