| To Rm{William Robotham - Chief Engineer}/Std. from G/Rb.{R. Bowen} 1260. G/Rb.{R. Bowen}1/K/73/W.9338. ---------------------------------------------------------- Fan - Wraith and B.III Sec. 5220. -------------------- Rm{William Robotham - Chief Engineer}/Std.7/AP.3.3.38. We have compared the costs of the alternative schemes of the Fan Spindle adjustment. In each case we have considered the Fan Spindle and adjustment parts, but only the necessary machining on the Water Outlet Bracket to accommodate the fixing of the Fan Spindle. The following are the comparative factory costs. (1) ECD.524 Scheme showing the Fan Spindle 4/6. rivetted to carrying plate. (2) ECD.243 Scheme incorporating an 6/- adjustable eccentric spindle with locking clamp. (3) ECD.219 Scheme which shows Spindle and 7/2. carrying plate produced as a one-piece forging. G/Rb.{R.
