Pultra Home Page Pultra Grinders Pultra 17/70 Capstan Lathe
At the top of the page, and carrying what seems to be a War Office contract number, this Pultra accepts what seems to be a standard compound slide rest assembly and other accessories--but is of otherwise a rather different overall design. A simple cantilever WW-type bed is used, with the headstock spindle driven by an overhung pulley on its left-hand end. This type of drive system was also used on the 17/50 and Series 17/70 models - but with the pulley hidden under extensions to the headstock casting. It's just possible that this is a development machine, made to test the concept. Even the compound slide rest was different, though the micrometer dials were recognisably "Pultra". Lower down the page is what appears to be a genuine Pultra lathe using a watchmakers' lathe bed. However, it's possible that this example is just the headstock, slide rest and tailstock from a Pultra mounted on the bed of one of the many unbranded WW (Webster Whitcombe) lathes manufactured before 1945. As the Model P Pultra was made to the WW standard, the writer has seen instances of parts from several makers combined into one machine. As all (or nearly all) major components are interchangeable on the standard-form bed, when buying a second-hand WW lathe it's wise to check each component for authenticity..
