The Raglan Mk. 2 Capstan. Using many of the same conversion parts as the Mk. 1, the Mk. 2 was based on the much improved and newlt-introduced Raglan Five-inch centre lathe. Available, like its predecessor, in various configurations, that shown above has the optional power feed mechanism to both turret slide and saddle - the latter also fitted with an automatic knock-off, actuated by a four-station rotary stop. The headstock was fitted with the normal Raglan mechanical variable-speed drive but was provided, in addition, with two electro-magnetic clutches which allowed an almost instantaneous change from high to low speed and back again. Using a single-speed motor (and controlled by a simple switch on the headstock) two stepless speed ranges were available: 85 to 500 r.p.m. on the lower setting and 285 to 1750 r.p.m on the higher. See below for details of how the system worked..
