Thought to have been manufactured by the J.E.Tilly Company in Australia, little is known of the Tillico Brand. However, one lathe has survived, a 9.5" x 40" gap-bed, backgeared and screwcutting example that must date from circa 1910 to 1925.
With a deep gap bed able to turn a disc around 33 inches in diameter, the lathe was heavily built and supported on two cast-iron plinths. Nine spindle speeds were provided, driven by a remotely-mounted countershaft, the maker recommending that it be arranged so that spindle speeds of 18, 28, 36, 43, 54, 83, 150, 230 and 350 r.p.m. were obtained. Screwcutting was by changewheels, of which a rather limited set was provided to generate pitches between 2 and 26 t.p.i and metric from 0.5 to 10 mm. Power sliding and surfacing feeds were by a separate power shaft with a simple quadrant-lever 3-speed gearbox to give three rates for each setting of the changewheels.
If you have a Tillico, the writer would appreciate hearing from you.
