Be sure your slot isn't too tight a fit. Some people dip the HINGE PART in vaseline or melted parafin. For any type of hinge other than CA type, I use some 6mil poly with a tight fitting slit over the hinge before glueing or inserting , this can be slit and pulled out after the glue has set. Try to get epoxy in the slot with a VERY thin coating on the end of the hinge. The glue on the hinge will push out, while the glue in the slot should push in.
