I'm just starting to use the flat pinned hinges after years of using the (no longer available) Granite State iron-ons. What I do is make the slots and dry-fit the surfaces, arranging them for allignment and freedom of travel. Once I have them where I want 'em, I drill through for my toothpick pins and put a drop of fast CA in the hole. This wicks into the joint and sets the hinge without coming near the hinge pin. Then I insert my toothpicks and wick another drop of thin CA down the shank. Clip, sand and cover with a patch of covering I punch out with a paper punch. Those hinges aren't going anywhere. For big planes I'd suggest using bamboo shishkabob skewers to pin the hinges.
