Not all CA hinges are created equal. I did an evaluation with gp and sig hinges a while ago. Slotted scrap balsa and drilled the centers of the slots. Inserted the hinges and dropped thin CA on both sides of hinges. Left them to fully cure before pulling them out with a pair of pliers. Result : the sig hinges came out without any balsa on it. The fiber cloth stayed inside the slot and only the middle plastic film came out clean. The gp hinges pulled out the balsa with them and no separation between the fiber/plastic film was seen. FWIW..............
