Like Pappy said try B&M first. Second take a piece of fine sand paper, rough up surface, coat tip section with lite coat of vasoline where it goes into but section. Clean out side of but section with cotton ball and alcohol. Let dry mix up small batch of JB weld epoxy put a thin coat all the way around and down past where it is loose about a 1/2 in. Take electrical tape starting below the epoxy wrap repair tight as you can and let cure fo couple of days. Vasoline is so epoxy won't stick to tip section.
