The door hinges are smart. I was wondering how to do that myself. Good job!
The original tutorial has you cutting the centre of the door hinge away, but on FW doors that leaves then incredibly brittle!
This way does need some sort of retrofitting to hide the bit of wire, but a small bit of plasticard should solve that and be relatively easy to integrate into a normal LR side.
In my case, its a doddle - im bulking it out with way more armour plating!
