Our first flexure prototype uses Ortofon AS-212
pillar and ancillaries (antiskating adjustment, arm clip etc), arm tube and headshell from Prototype 5
, and custom machined central parts.
I have chosen a horizontal flexure configuration that is suboptimal in many respects. First, the whole weight of the arm and counterweights is deflecting the flexure. Second, in this position flexure is free to move in the azimuth plane. Why then?
This isn't a production prototype, but a test to expose the problems. Loading the flexure will give answers regarding its stability and longevity. Allowing for azimuth movement would let us measure it and select the material less prone to flexure in the "wrong" plane. Also, it's a bit simpler to achieve single point of vertical and horizontal rotation this way, thus removing one extra unknown from the measurements.
