After many measurements I cut the skin off for the door area. Just using a straight hobby saw as I have done when cutting the ailerons and rudders out. Slow but easy. In Pic 2 you can see I've removed the minimum foam to fit those green hardpoints. I'll attach the hinges to those.
This green stuff is Garalite G10. I used 4mm which is super stong. If I was doing it again I think 2mm might work or 3mm at most. 4mm is overkill and just extra weight. On the plus side it has a bit of thickness that I used as part of the fixing idea.
Pic 3 shows that I've made a bit of a lip by cutting into the foam past the edge of the top ( or bottom ) surface. The idea is that the G10 slots in and some of the forces acting on the open doors will be transfered to the top skin as I'm going to sort of inlay the hardpoint in here so that are flush and perpendicular with the edge of the door opening. I've read this geomety helps the doors work properly, or rather I've seen people with problems when its not done that way. The inlay however is my idea and arguably lighter by about .001grams hahaha
I put 10 hours for this log entry and as with most of them it took a bit longer and over a couple of days. I tend to think a lot and go slowly doing something for the first time trying to see everything that might go right...or wrong and the consequences later . If you ever want me to help with this step...I could now knock it off in an hour or so. ;)
