I use the Hobbico Hinge Tool with CA blades and drill a 1/8th inch diam hole down the middle of the slot. I then clear the the slot and hole of wood fragments and drop CA down the slot and hole. I saw this in RCM magazine and it was in the instructions of one of my kits. I have used this method a long time and no failures yet. The Hobbico Hinge Tool is great but you need a guide slot to get started otherwise it will bounce all over the place.
