Essentialaudio, I went thru that painful experience (trying to adjust offset and overhang on a WT Ref tonearm) on behalf of a dear friend of mine, whose only crime was that he wanted to install his new Dynavector 17D3 cartridge, which has a very short cantilever and hence a shorter than normal distance between its mounting holes and the stylus tip, in the horizontal plane. It seems you have to loosen a bolt accessible only from the bottom of the WT plinth in order to twist the tonearm on its shaft, to adjust the overhang. This was difficult, even for two people, given the weight of the plinth, the instability of the WT platter, etc. But even when we were eventually successful, it proved to be next to impossible to maintain the correct adjustment while tightening down on that bolt beneath the chassis. It was not a pleasant experience.
