Having fitted the hardpoints I fitted three nut plates to each piece and match drilled them into the hinges. That stuff always takes a while with nice little countersunk rivets and neat holes. The G10 is so hard that it is no problem using hard rivets rather than the soft type to hold them. I also drilled many lightening holes which will also work for 'glue fingers'.
While these hardpoints are only being glued to relatively soft foam, its over a reasonable area. I got the shine off the G10 for the epoxy bond and have to say they looked great...and no one but us will ever see them.
Pic 2 shows we are ready to go and pic 3 is the pieces floxed in place. I hot glued the hinges to the sides to hold them, made sure those screws were not going to be covered in glue and used a couple of bits of bamboo just to be sure the hardpoints didn't bow out of position.
