Summary of Contents for Holbrook Minor

  • Page 3 The alliance has been achieved with the added advantages of contemporary design. The 'MINOR' is, at present, the smallest machine in the range and has been designed to close the gap between the precision bench lathe and larger precision lathes such as the others in the Holbrook range.
  • Page 4 The totally-enclosed gearbox used only for threading and is engaged by a push-in knob on the end of the headstock. By combination dial selection, thirty changes from 8 to 64 t.p.i. can be made. Other ranges can be supplied if requested at time of order and special threads or metric pitches obtained by change gears on an adjustable quadrant can also be arranged.
