My Biax 7/ES breathes again. New commutator and armature rewind, new bearings and new brushes. It has absolutely no wear on the sliding faces so I am expecting to get many years of service from this tool.

The bearings are 6001-2z and 608-2z both C3 the brushes are the same as for the 7/EL model and a guy on German ebay was selling those for 8 euro a set so I bought a three sets. I am awaiting a new cable strain relief grommet from Hong Kong and this project is finished.
