I've been thinking about how to lock the doors and have some doubts about the whole thing:
- the pax door handle can be secured with a lap-strap - easy.
- my first idea for a latch was to cut a slot in the door rail and use a baggage door lock. Not such a good idea though. Firstly, the door rail is structural and secondly the door itself could be easily jimmied and the fiberglass would just break. Could be reinforced with some aluminium backing.
- then I thought about trying to make some sort of "wheel-clamp" type device that would fit over the handle so you can't get access to the button to unlock the door. To be robust enough, it would have to be made of steel so not so easy to put together. Also a bit clumsy.
- take the handle off? Too much wear and tear and vice grip could be used.
- I hadn't thought about the above solution which interferes with the latch mechanism. I'm pretty sure I can use my spare baggage door lock to make that work so only one key to worry about.
The only other thing that occurred to me was that with all these solutions, the actual door structure is not that strong and so anyone really intent on getting in could. The avionics are expensive and on the face of it a valuable target. But is that really the case? How easy would it be to sell any of it on? And if you are on an airfield, you already have one level of security. Perhaps a simple fabric cover which hides everything and has to be taken off would be enough deterrent against a casual thief.
Overall, though, I like this solution here. I have 4 weeks leave starting next week - 3 weeks aircraft building (and moving to the hangar!!) and a week's golf

I'll see if I can incorporate this idea.
