How has being an SME member impacted your personal life and/or professional career?

The networking, mentoring and connectivity that SME afforded me had a profound effect on my subsequent career.  Although my SME profile indicates that I have been a member since 2004, I have actually been a member and involved in SME activities since the 1980’s.  At that time I was involved in a family business that manufactured wooden shoe pegs that at the time were a popular material for tumble polishing plastic items such as eyeglass frames, dental acrylics, buttons, jewelry and the like.  This family business was over 100 years old at the time and used steam era machinery to produce its product. [SEE: http://www.slideshare.net/dryfinish/kearsarge-history-2011rev  ] The company lacked understanding of the technology and I became a member of SME’s Burr, Edge and Surface Technology (BEST) division.  Involvement with this group led to my acquaintance with John Kittredge, LaRoux Gillespie, Larry Rhoades, Bernard Hignett, Sam Thompson and others, some of whom were to become SME mentors and who coached me into contributing written technical material on mass finishing processes.  [SEE: http://www.slideshare.net/dryfinish/sme-mr-85-hardwood-media-dry-process-applucations  and   http://www.slideshare.net/dryfinish/almost-buffed  ]  With the help of these SME mentors I established a working process laboratory from which I developed a new line of abrasive and polishing products and also developed new mass finishing processes for barrel, vibratory and centrifugal finishing systems to find the solution to customer finishing problems.  Later additional SME mentors such as Jack Clark and Rodney Grover helped me with work connected to the product launch of Dr. Michael Massarsky’s Turbo-Abrasive Machining technology in North America [SEE:  http://www.slideshare.net/dryfinish/october-2013-f2-deburring-1  ]  and as a consultant and advisor to industry on high energy edge and surface finishing processes  [SEE:  http://www.slideshare.net/dryfinish/november-2012-f4-deburring-1-final  ]

How long have you been in manufacturing and how did you first get involved in the industry?

I have been involved in manufacturing since 1975, worked my way up as a millwright and production manager.  Among my early duties was operating an 1878 Portland Marine and Locomotive stationary steam engine that was the power plant for the shoe peg manufacturing plant that belonged to the family business.  As time went by I became more actively engaged in process and product development activities.  See below some examples of surface finish research experiments and projects I worked on.

If you’re a new member, how did you hear about SME?

 I am not a new member, I am an old member.  I became an SME member because a mentor figure, Sam Thompson all but dragged me down to the SME booth at an SME trade show in Hartford CT back in 1983 and made me sign my name to an SME application.

Have more to share about your manufacturing experience or the industry?

 SME was an early adopter of mass finishing technology education programming.  Through its BEST Division {Burr, Edge and Surface Technology) it sponsored conferences and symposiums and published technical papers and articles on the subject.  However this an area of industry that is still often neglected by the mainstream manufacturing community, and most engineers graduating from school have little understanding of its importance and how critical it can be to overall part and component functionality and performance.
