Luthiers, cabinetmakers, carpenters, or animal renderers.... I have an old mandolin whose neck started to shear off after an unfortunate night in the cold last year. I finally got the nerve (and coin) together to take it into a shop here in Ottawa, but the guy just looked at it, shrugged, and declared it cheaper just to buy a new one than to ask him to wrestle with it. So, could anyone recommend a glue that I could try myself to use? I met a guy this summer who does ukulele workshops (i.e., building them), and he was all over a particular animal-fat-based type, but damned if I can remember what it was. Any advice would be much appreciated.
