Fine Woodworking managing editor Mark Schofield goes behind the scenes of our methodical glue stress test to show you how we tested six types of wood glue. Schofield heads to the Department of Materials Science and Engineering at Case Western Reserve University for a peak at the Instron joint-breaking machine in action.


The glues tested included a traditional yellow polyvinyl acetate (PVA) glue, a Type I waterproof PVA, a liquid hide glue, a hot hide glue, a slow-set epoxy, and a polyurethane. Each glue was tested using three types of joints on three types of wood.
