Super Glue is truly a 'wonder' glue. There are many times when I am carving feather tips and have broken them off, usually along the grain. Nothing is worse that trying to fix a broken feather tip. Seems like you can always see the break whether you glue the broken piece back or where the joint is when inserting a replacement piece. Super Glue has eliminate a lot of those broken tips for me. I use it in two ways; first, on a real delicate tip, I will soak it in Super Glue before putting the finishing detail on it and then the second step is to soak it again when it is finished to make it harder to break. The two brands I like are the Gorilla Super glue I get at Home Depot and the Original Super Glue (Concentrate) in the 10 oz. bottle found at Dollar General stores. (I don't care for the Super Glue that come in the little squeeze tubes) How do you use Super Glue and what kind do you prefer?
