| 1116 & 1044. To By/Ald.{F. Allwood - Experimental Design} c. to By.{R.W. Bailey - Chief Engineer} Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell}3/JH.13.12.38. B.60 & B.80 CRANKSHAFTS. (1) This memo. to confirm our verbal request that you will look into the possibilities and scheme out for a 2.75 dia. main journal crankshaft for B.60 and B.80. Regarding the B.60 this should be carried out for the crank with R.R. type balance details of which have recently been instructed by By/CS. (2) Further to the scheme you did for us some time ago, whereby the camshaft in Monikrome runs direct in the crankcase together with a Monikrome camwheel the latter is giving trouble due to noise. Will you please scheme us a Fabroil camwheel for the same jobs on the lines of the one at present used on B.60. Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} | ||
