| Hs. {Lord Ernest Hives - Chair} from BY. {R.W. Bailey - Chief Engineer} C. Mr Shelton. x3653 BY15-P2.3.20. x3653 x3456 RADIATOR - RE BLANKING PLATE & FITTINGS. In our original scheme we arranged for rubber washers under the steel washers in the front of the radiator, but when the scheme was received from the Experimental Department later, they deleted the rubber and replaced same by leather. If rubber had been used as originally intended it would have acted as a spring washer and would not have dried up under the action of the heat, which was one of the main reasons for originally using rubber in this position. We would like to know now whether you would suggest using rubber washers again or a spring washer, as the leather will certainly dry up and allow the bolt to work loose, which in turn will rub a hole through the radiator tube.
