Coronet Miniature Precision Lathes Home Page
Using many components of the Ruby, including the complete headstock and tailstock units and a bar-bed, the "Jewel" was arranged conventionally with small splayed feet and a carriage driven by an overhung leadscrew running down the front of the bed. A single swivelling tool slide was fitted with the whole machine looking remarkably like the larger but much cheaper and less desirable Velox from the early years of the 20th century. Although the great majority of these lathes were made as short-bed models, there was a much longer one made, this offering something like 15 inches between centres. The tailstock spindle, already provided with a lever-action feed (by the simple expedient of peg passing through a slot cut through the top of the casting) was machined to take the same 8 mm draw-in collets as the headstock.
