      T.N.C. CamSon Lathe

      T.N.C. Adept Lathe

      A simple, plain-turning bench lathe for use by an Amateur, both background to the T.N.C CamSon and little of its origin are known. However, another lathe with T.N.C. branding was a version of the little English Adept lathe - a machine that, like the CamSon version, was thought to have been made in Australia.
      With a centre height of just 45 mm and a capacity between centres of 200 to 250 mm, the T.N.C. CamSon was fitted with a proper compound slide-rest assembly, the cross slide having 75 mm of travel (driven by a 5/16" diameter, 18 t.p.i. feed screw) and the top slide (able to be swivelled through 360?and fitted wih five gib-strip adjustament screw) 65 mm. To protect the cross-feed crew, sheet-metal covers were fitted at the front and  back of the top slide, the front section, if fitted, restricting the slide travel to just 65 mm. Small, non-adjustable micrometer dials were fitted, though the graduations used are not known.
      Cast as-one with the headstock and with integral feet, the ground-finished, gap-equipped bed had a V-way front and a flat rear way, these being shared, to the determent of long-term accuracy, by the No. 1 Morse taper tailstock
      Formed as a casting no wider than the cross slide, the saddle was fitted with a full nut in bronze on its front underside, this being connected to a 7/16" diameter, 12 t.p.i. leadscrew. To turn the leadscrew, at the tailstock end of the bed, a large, full-circle handwheel was fitted, this driving though enclosed reduction gearing to give a finer, steadier feed for a better surface finish.
      Running in unusually large anti-friction rather than the expected plain bearings, the headstock spindle was bored with a No. 2 Morse taper socket on its nose. A cast-iron, 4-step V-pulley to take an A-section V-belt was fitted, this being driven from a separate, rear-mounted countershaft in aluminium fitted with a clutch built into the large driven pulley.
      If you have a T.N.C. CamSon lathe or any literature about them, the writer would be most interested to know.
