I have a 5th edition 916 Korber Power Plant and am having trouble getting it together. Still dry fitting because of the problems. On the 24 windows big side of the building, the opening for the windows is too big in some spots and they fall out, opening situation makes it difficult to line up the window in some spots. Was this a common problem back then? I have trimmed the windows are per instructions. (only trying to do one vertical row of windows). Is there a trlck to this? Also the walls are warped some, and the building is painted. A fix anyone? I am an old modeler and I never had problems with a model like this. Are there better directions for assembly out there? Any help would be greatly appreciated. THIS IS IN NO WAY A SLAM AT KORBER MODELS OF TODAY, so please do not turn it into such. I am just a little frustrated and looking for some tips to help rectify the situation. I think if I use super glue I would not have time to line up the windows correctly.
