Get some T pins or push pins to center the hinge. Put the pin through middle edge of hinge so you get the same amount in each side. Just a drop or two at most is all it takes of this CA glue also. It spreads out through the hinge and holds. You also want to make sure you get the ail, rudd whatever your hinging to fit tight against pin. Once you put that CA glue on it will stick quick about 1.5sec. so be sure your right. Hope this helps a little.
