It is really important to know that mixing adhesives can be fatal to the quality of a joint.
For instance, using aliphatic glue to repair a hide/fish glue joint that hasn't been completely cleaned of all original glue results in a mixture between the two glues which is far far less strong than either separately. (again, painful personal experience, with a 'cello neck. Why is it always the things that hurt me?) Anyway, cleaning crystalized hide glue isn't that hard to do, but being sure you got it all really does make it worth the trouble to get it into the hands of an experienced maker. ray To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
