Abstract

Development of a tension test suitable for quality control on finger joints and other end joints in wood is described. The specimen used is rectangular and can be prepared rapidly with a planer-type table saw. The approximate size of the specimen is 3/32 by 3/4 in. in cross-section by 10 in. in length.

Because the specimen is simply prepared and can be tested quickly on a universal testing machine, it is also well suited as a screening tool in research and development on end joints in wood.
