Dear visitor, my name is Wolf Ruecker from Langenlonsheim Germany and I am one of a group of plumb bob collectors from around the world who report and exchange information about plumb bobs. This group is represented by collectors from the U.S.A., Canada, from Europe (Spain, Italy, Germany, Greece, Netherlands, France and Turkey) and from "downunder" Australia, who met - in 2006 in Istanbul,Turkey for our 1st International plumb bob collectors meeting

- and in Oct. 2010, a third meeting in Cologne and Langenfeld, Germany.

The first written publication on plumb bobs was from 1991 to 1994 “THE PUMB LINE, the definitive work on the simple plumb bob“ by Bruce Cynar from Fort Wayne, Indiana, U.S.A. This was continued in 2005 by Nelson Denny from Hadlyme, Connecticut, and is available as “THE PLUMB LINE CONTINUUM.”
Since my specialization is patented plumb bobs, 50 weekly newsletters in 2007 were devoted to this subject. This includes over 300 pages and over 150 patents. In 2008, I wrote monthly on general topics having to do with plumb bobs and distributed it by email (PDF file) to over 100 recipients in the world (U.S.A.(60), Canada, Australia, New Zealand, Greece, Spain, Turkey, Holland, England, France, Italy and Germany. This edition is available in English, German and Swahili.
To keep up the tradition, Wolf's PLUMB BOB NEWS will appear monthly in 2009, 2010, (not in 2011), 2012 and 2013 too. As before, they will be distributed by email, free of charge and now for download from this site, page "download PUBLICATIONS".
The topics will focus on 4 tool types I collect:
PLUMB BOBS (stand for the VERTICAL), PLUMB LEVEL with plumb bob, the forerunner of the levels (stand for the HORIZONTAL) ANGLE MEASURING INSTRUMENTS with plumb bob; (stand for the ANGLE) and CHALK LINES, SNAP LINES (stand for the STRAIGHT LINE)
