Here are some photos Tack of the Duck tail.
After cutting of the lid section
I cut an glued (aeroldyte) strips of pvc on the insides to allow for a lip
Modified a lock tongue so it hooks on a bolt
sat the lid back on and added spot putty where required using glad wrap between the edges to stop it sticking together and with sanding and refilling until al was right I then fitted the short piece of piano hinge to it.
Also fit a extra piece of Perspex at the front if the lid as a guide to help it close properly.
Hope that this is at least a little clearer than mud and helps some what.
