The console height dimension is calculated by adding together the
distances between the face side of the headstock and that of the
distributor ring. If the headstock face surface is machined, the
calculated dimension can be taken as the height dimension for the
spacing console. If the end face of the headstock is unmachined,
the height dimension should be calculated by adding together the
individual distances then subtracting 4 - 5 mm. In accordance with
the sketch overleaf, the spacing console comprises two shells and
is made of suitable steel plate. The main dimensions match the
individual chuck sizes, and can be taken from the sketch overleaf.
Incidentally, the spacing console can be customized, but it should
achieve the stability of the design shown. The spacing console is
mounted using 6 M8 threaded holes in the chuck distributor ring,
