Another hint. When the hinges are being glued to the door, you can tape the area between the door and the fuselage lip to prevent Epoxy from running into it and accidentally bonding the door to the fuselage.
After all of this is accomplish, you can now add screws if you wish to. I personally don't use them becasue in case of an accident I would prefer for the door to separate rather than tearing out part of the fuselage.
Any questions, feel free to shoot me a PM. Glad to help.
