RE: ARF hinge question, how to pin them?
It will keep the hinge in place if the glue fails not if the hinge tears
you can also use a piece of push rod guide tube chuck your drill bit in a pin vise cut the tube to leave only the depth you want to drill exposed put a piece of blue painters tape over the hinge area mark and drill to the stop glue the pin in and if you want take a paper hole punch and make a covering material patch patch to hide it
