Fleib, On 8/29 or thereabouts you wrote, "Lew,
You mean 21mm short of the lead-out groove, which would be about 80mm from the spindle?" Then Hi-ho made some further comments to indicate that 76mm is correct.
But if you guys will look at the diagram in the article quoted by Hiho, follow the arc formed by the dotted line. In order to achieve zero tracking error (stylus tangent to groove) at point B, as defined by the designer of the RS-A1 in that diagram, the stylus needs to hit the label or the run-out grooves of the LP where that arc comes closest to the spindle, which I think is indeed about 21mm from the spindle. Thus we were talking about two different things, in one case how to mount the arm, in the other case, where on the LP playing surface we wish to achieve the one point of zero tracking error.
As to the Rigid Float. All that babble about how the "bearing" is constructed does not allow me to form a picture in my mind of how it works, how something can be both "rigid" and "floating". I would need to play with one to convince myself. Well Tempered liked to sell the idea that their tonearms have no bearing and hence no bearing friction; the problem is that their bearing (which IS a bearing, semantics notwithstanding) has a fair amount of play and so low friction is achieved at the expense of wobble.
