How it all started


The book, METRIC STANDARDS for Worldwide Manufacturing (800 pages, 500 tables, was developed over more than 40 years of hard work and sometimes struggles. The participation during 1972 and 1973 as the Massey Ferguson member of an ad hoc metric study committee of the Society of Automotive Engineers (SAE) Off-Road Vehicle Council with members from the other farm machine producers such as John Deere, Caterpillar, Clark, Case, International Harvester, etc. gave me the idea to author the book. The first positive break came when the Past Director of Engineering Standards (Past President of ANSI) for General Motors endorsed the project and made it possible to use International Organization for Standardization (ISO), American Society of Mechanical Engineers (ASME) and Industrial Fasteners Institute (IFI) standards in the proposed publication. He also nominated me to chair the ANSI B4 committee on Limits and Fits, and we drafted and published several standards. The most important one, ANSI B4.2-1978 Preferred Metric Limits and Fits, became an important part of my publishing efforts. The ISO tolerance software () was also developed and published in agreement with the above standard. Later the ANSI B32.100-2005 Preferred Metric Sizes for Flat, Round, Square, Rectangular, and Hexagonal Metal Products was also drafted by me. The preferred sizes and tolerance zones, h11, h9, h7 and h6, covered in the ANSI B4.2 standard are also covered in the new metal products standard, which are standard tolerances for round material stock in all major industrial countries in the world. At that time, I worked for the global company, Massey Ferguson in Detroit, and they were also very much interested in me developing drafting and engineering standards to be used in their worldwide engineering and manufacturing operations.


World Metric Standards for Engineering was published by Industrial Press in New York 1978. It sold in the thousands of copies around the world. The publishing company was not interested to publish my proposed second edition since ASME required royalty payments for use of their standards. The result was I worked out an agreement with ASME Press to publish the book. The title was changed to METRIC STANDARDS for Worldwide Manufacturing, and the second edition of the book was published in 1996.


In 2002 I proposed to publish an electronic version of the book. At that time, ASME Press, had no interest in helping me publish the e-book, but they gave me permission to publish it on my own. The third edition of the metric handbook was published in 2003 and distributed by the American National Standards Institute (ANSI) Electronic Standards Store . Many companies now make the e-book available on multiple work stations over their Intranet.
