| 1116 To Jnr.{Charles L. Jenner} Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation}8/JH.7.12.39. Crankshafts. Will you please produce a new drawing of a B.60 crank having integral balance weights. We need this rather urgently in order to obtain a reliable cost for such a crank which will be machined only on the working surface. The Jaguar crank is a sample of balance wts. that do not cost very much. The journal size we have standardised is 2¾" dia. Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation} | ||
