The barge cement does not need that length of time to be ready to bond! My suggestion is to use a toothpick to smear the glue on the two surfaces. Then again, use toothpicks to keep them separated for like 5-10 minutes (at room temp), remove the toothpicks and press and work the mating surfaces together. This should work well enough for the grip, and it will be easy enough to clean up the excess after it dries. Barge is rather simple to work with. If you wait the full 15-20min, as soon as it touches the other surface, it will want to bond. If you only wait 5-10min, you should be able to work it into the shape you want, and it will still hold until you are ready to remove it. Do not use super-glue on the finish of a bow, as it can damage or discolor it!
