Neil,
A good reference is a paper written for the 1974 Sympo titled "An Experimental Evaluation of Some Popular Modeling Adhesives" by Thomas Ersted and Edmond Smith. They developed a method to gluing two pieces of balsa wood and then subjecting a bending load to the glued joint until failure. At that time ambroid tested out better than testors A and B. Jeff Annis
