Our fan construction, though reliable, appears to me to be somewhat costly. I think we should study the methods of construction of up-to-date American fans and base the rationalised fan on their practice. I know we have had failures in the past when we have tried to cheapen the fan construction but this should not prevent us from making further efforts. Rm.{William Robotham - Chief Engineer} | ||
