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} | ||
