Did you try scraping the old glue off first?
Well, the next time I try gluing it, I can scrape off the old glue, but as this was the first time I tried gluing it, if there was old glue on it before I got started, I'll be ticked ... as for pinning it, that is an excellent solution, but I don't have a hobby drill or brass pins, so I think I'll try gluing it again before I go that route
