Over the last two days I have been steadily looking at the best way to fitt the baggage door to the body. I basically did a stuff up, or at least what I thought was a stuff up.
I centered the piano hinge and fit it to the baggage door PRIOR to hanging it on the door frame. End result, it had a gap at the top and no room at the bottom. At first I thought this was a problem, however, soon realised I had the ability to access the piano hinge wire for installation and separation should I so desire.
Therefore what I thought was an issue, turned out quite well. :-)
