Mount the comparator brackets (C and D, Fig 10) to the
back of the headstock and tailstock with socket head cap
screws and lock washers.

The tailstock bracket has elongated holes, so it can be
aligned with the headstock bracket.
The comparator allows holding a sample work piece for
optical reference and comparative measurement taking.
