  - With this string, wrapped directly around motor shaft, and using weight of the spindle as the sole downward force, it is possible to mill a reasonable PCB with the conical bit, and wax milling goes well.  Measured dF/dz is much higher than before, 120 N/mm.  
  - The xy stage by itself has dF/dy ~ 40 N/mm.  With wax block on table, at the top of the block dF/dy = 30 N/mm.  Extra compliance is due to rotation about the single x-beam as a function of sideways flex of bearings.  
  - Applied kevlar string to the xy stage.  Now the stiffness of the stage, dF/dy, has doubled to 80 N/mm.  When the table is added, and a wax block attached, the stiffness at the top of the block is still low, about 40 N/mm.  Now the 20mm width of the x-beam is the limiting design parameter.
+ - Made an eccentric nut as a bearing adjuster, following design from Ender machine.  See below.
