Chipped off a piece of mahogany about one inch long by 1/8 inch wide by 1/4 inch deep, so of like a big sliver. Used Starbond super fast thin ca glue - it flows like water. Stuck the piece on and taped in place for 20 minutes. When I stressed the piece it came loose. Still seemed sticky. The ca glue works for me sometimes, other times the piece just falls off. Am I using too much? Stessing too soon? Are there any techniques I am missing?
