Last week, my wife told me that she couldn't get the roof to close at which point I discovered that there is very little practical help online. So I am publishing my exploration and discovery ( you will probably be amazed how long it takes me to spot what now seems obvious)

Sorry about the poor camera work and rambling explanations. I don't know anything about making You Tube videos .

There are a few videos, which together get us to the end of the project and I'm publishing all of them as there might be useful snippets in each video.
