HPS.{Horace Percy Smith - Experimental Factory Mgr}3/EP.{G. Eric Platford - Chief Quality Engineer}11.12.36 PH.III RADIATOR SHUTTERS. Handwritten: W/en Ru /SMD{J. Smedley} The assembly of Ph.III Radiator shutters is such that they do not stay put, for example :- Shutters are assembled with radiator in horizontal position with .002" end float in each shutter. Radiator is raised carefully to a vertical position, and in doing so the end float increases, varying from .005" in end shutters to .025" - .030" in centre shutters. Once "sag" has taken place, it stays put, and it is necessary to re-washer to remedy the excessive float. The natural lifting point of this radiator is by the wing stay supports, and by so doing the results are worse. SUGGEST. 1. Bearing strips be made in one piece instead of three. 2. Bearing strip to be tapped and pivot pin screwed. 3. Fit rubber washers under pivot pin if desirable for appearance, and cleaner job in service. REASON Cheaper, simplify adjustment and assembly, simplify service. Herewith drawing Ex.I.94, showing points raised.
