Hollingworth} c. Rm{William Robotham - Chief Engineer}/ABR.{A. B. Roberts} Rm{William Robotham - Chief Engineer}/Ed.{J. L. Edwards}14/MH.{M. Huckerby}22.8.39. I/C PULLEYS. Will you please make up a set of cast iron pulleys machined only in the V-groove and on the boss, all other faces being left as cast. Clearly this will be a cheaper job and we are anxious to find out the effect of any out of balance forces. Rm{William Robotham - Chief Engineer}/Ed.{J. L. Edwards} | ||
