We also enclose herewith 2 marked blue prints of PL.165 and 2 blue prints of LOP. No. PL.165. Since RE.1102 Crankshaft is made from the RE.191 it is necessary for us to send an extra print for forging. With regard to the 2 Sprockets RE.1104 and RE.1105 we suggest that the first experimental sets have the teeth cut by Renolds as it is unlikely that we have a suitable cutter in stock. These details have been made in accordance with the above scheme and are to be used on a B.60 incorporating the "2Way Thrust Faces" as per PL.7., and the Humber type Damper as per PL.90. This completes the instructions for the above. Rm{William Robotham - Chief Engineer}/HH. | ||
