Project Nano Rotation Stage
Checking of actual dimension of all bearing housings to know which high precision roller bearing fits best into which housing:

Precision machining of all bearing housings to exactly the same height to make sure the bolts can be adjusted in the micron range:

Result of measuring at the tightly lapped surface of the clutch is below 1 micron.
Pre-adjustment of measurement tool: -1 micron (MarCator1088 of MAHR with corresponding PC software):
Requirement: - Resolution 0.04" - Rotation 360°, unlimited - Max. Force 3000N - Torque 2Nm - Compact
