Materials and Processes in the Manufacture of Civil War Small Arms


1 PDH Hour will be awarded for this meeting


About the Topic:

The features, performance and reliability of the Civil War era US Springfield and British Enfield rifle-muskets are briefly discussed.  The “American System” of wood- and metal-working technology that enabled the mass production of military small arms with fully interchangeable parts in American and British arsenals ca. 1840-1865 is described using period illustrations.  This technology is contrasted to the non-interchangeable “Craft Systems” employed in the US and Britain ca. 1800.  Results of metallurgical examinations of selected components of original US Springfield and British Enfield rifle-muskets give insights to the materials, metal working processes and heat treatments available to mid-19th Century arms-makers engaged in the interchangeable "American System” of manufacture.  The rifle-musket is shown to have been a value-engineered arm that employed low cost materials and metallurgical treatments, yet was capable of incredibly robust performance under combat conditions.  Example antique rifle-muskets will be displayed.  The life span of the muzzle-loading percussion rifle-musket in military service was short – introduced in the early 1850’s, then replaced by single-shot, metallic cartridge breechloaders in the late1860’s.

About the Speaker:

Mr. Harkness holds BS and MS Degrees in Metallurgy from Case Institute of Technology and Case Western Reserve University, respectively, and is a Fellow of the American Society for Materials International (ASMI).  He retired in 2011, after 33 years, from the position of Principal Scientist, Alloy Research and Development, at Brush Wellman Inc. (now Materion) in Mayfield Heights, Ohio.  His research interests there included Cu-Be and other Be-containing alloy development, raw material and component parts fabrication technology, new products and physical metallurgy.   He is co-inventor on several US and foreign patents for lean, low cost, high performance Cu-Be alloys; has written extensively on the performance attributes of Be-containing alloys and has contributed to articles on Cu-Be and other Cu alloys in the ASM Handbook series.  He is a Past Chairman of the Cleveland Chapter ASMI.


Mr. Harkness is also a life-long student of military history and technology.  He is Past President of the Cleveland Civil War Round Table, a member of the Company of Military Historians and the Ohio Gun Collectors' Association, a former Civil War and Revolutionary War re-enactor and has shot original Civil War small arms with live ammunition extensively in target competition in the North-South Skirmish Association.
