| To By.{R.W. Bailey - Chief Engineer} from Rm{William Robotham - Chief Engineer}/Std. c. Da.{Bernard Day - Chassis Design} X K044. 840. B.50 RADIATOR. We send you herewith Rm.{William Robotham - Chief Engineer}487 which is a rough scheme indicating some modifications to B.III radiator to reduce its cost in order to use same for B.50. Summarised, these consist chiefly of - (1) Making top tank in one with matrix plate and shaped so that tank can be dip-soldered to matrix on one edge. (2) Substituting curved hose water connection for curved copper pipe water connection. (3) Cheapened and more effective filler scheme. (4) Top hinge used as single central radiator stay. (5) Matrix unit used to brace shell - in view of the former's strength it seems uneconomic not to do this. (6) Cheapened lamp and wiring supports - scheme shown uses brass die cast pieces in order to avoid machining and hand finishing. B.50, however, may have quite a different shape shell and we think that the possibility of mounting the lamps direct off the shell with the wing stay only supporting the wings (as per American practice) should be investigated. We would like you to incorporate these ideas as far as possible in the design of B.50 radiator. Rm{William Robotham - Chief Engineer}/Std. | ||
