GEARBOX
Two alternative types of quick change gearbox may be fitted to the lathe.
The standard gearbox (i.e. that normally fitted to gap bed machines) provides a range of 45 longitudinal and cross feeds, 45 threads covering the Whitworth range and 12 metric thread pitches.
The alternative gearbox (i.e. that normally fitted to straight bed machines) does not provide metric pitches and covers a slightly different range of feeds and Whitworth threads (including 114 and 23 t.p.i.).
The full range of feeds and threads for both gearboxes is shown below.
