      CYJAX Lathe - Australia


      Looking as though it might have been inspired by the design of a Colchester Master from the late 1930s and 1940s, this CYJAX lathe carries a riveted-on plate proclaiming: CYJAX Engineering & Welding Works Melbourne. Of around 6-inch centre height and 40 inches between centres the lathe had a headstock which, like the Colchester, used a single lever on the front face to select the high/low range and two more, pivoting from the back of the top face, to change the spindle speeds. In a rather modern style the levers were not cast, but steel bars tipped with plastic knobs. A spindle clutch was fitted (a refinement found on only a few of the Colchester range at the time) and the tumble-reverse drive to the rather German-looking screwcutting and feed gearbox was on the outside face of the headstock and not, as more commonly arranged on lathes of this size, on the inside where the fast-running gears would have lubricated by the headstock oil.
      Both the V and flat way bed and the carriage, with its unequal length saddle wings T-slotted in traverse (one to the left of the cross slide and two to the right), also looked to have been be Colchester inspired - as did the apron, with two vertical slots to engage the power sliding and surfacing speeds. However, unlike the comparatively crude Colchester  arrangement of selector that had to be slid and lifted into the required slot, the CYAK had a lever in each with a clutch action to engage the selected drive - of course, some sort of interlock would have been provided to prevent their simultaneous use.
      If any reader can add to the story of the CYJAX, the writer would be interested to hear from you.
