Well I think that I have now figured out how to hinge the outer gear doors. Because the hinge line is not parallel with the wing cord this small door needs to be hinged from its front corner.

I haven’t actually hinged it as of yet, I need to get some small Robart pin hinges but will have a go later in the week so wish me luck!

I’ve now got the middle doors attached to the legs after machining up some aluminium spacers and filing them to the correct angles and drilling and tapping the legs to M3. An M3 bolt passes through the door, spacer and is threaded into the leg.
