![]() However, there may have been a third, or at least a maker's variation on specification (possibly to use up spare parts) - a 1978 SAG180 being found in the US with the A-B-C-D-E gearbox and a 2.25' spindle bore (thus being, in effect, a SAG14 labelled as a SAG180). As Graziano subjected the machine to continuous improvement, it is difficult to be specific about changes to the design however, in summary, there were at least two versions of the SAG180: a 2' bore plain-bearing spindle with an 'A-B-C' screwcutting gearbox and a 1/2' pitch leadscrew, then a type with a Gamet bearing, 'A-B-C-D' gearbox with a 3/8' leadscrew. Generously equipped for a 1960s model, the 180 had, as part of its standard equipment, a 12' independent 4-jaw chuck, fixed and travelling steadies, a Herson quick-change toolpost, coolant and spanners.
