And the first problem realised ... the side walls are about 1/16th to 1/32nd to short to mate up with the front and rear walls properly. I don't recall that being an issue with the last one I built.
That happened on my HO scale model also. As you can see from my interior photo, I had added some black painted masking tape along the top edge on the inside to prevent light leakage. On the outside, the eaves cover the gap up. Although at this point, I haven't added the light bulb yet.
Got the roof sections on AFTER having to remove the tabs for the holes as they did not line up and were too small to accommodate the tabs properly:
Not sure what I will do the roof in. I am tossing up between Corrugated Iron (Grey) or Grey Shingles... never liked the roofing material that comes with these kits.
Okay, I am an idiot - I just realised that I have glued the roof in place BUT, haven't put the front door or windows in!!! This ought to be fun then ..............
I haven't considered using Elmer's white glue - it never crossed my mind. There is another "Glazing" product (can't recall it's name) that I get from Hobby Lobby whenever I am near one, that is also cheap and works well.
