As soon as the B.80 water pump with the Morgan Stuart gland is completed, we should be glad if you would proceed with this job. We have obtained a relief valve from the British Thermostat Co., but have not as yet made it work satisfactorily. We are developing the job, however, and as soon as it behaves properly we propose pressure cooling 9.B.V. This car is at present equipped with a Serck fan and tube matrix and we consider the test will be useful in testing the endurance of this type matrix under pressure conditions. Copper brazing is only possible provided the overall section of the job does not exceed 11" x 5" so unless the matrix is made up in two halves we do not see how this can be applied. We think the job deserves consideration but at the same time we believe the soldered fan and tube matrix will be satisfactory. Rm{William Robotham - Chief Engineer}/Ed.{J. L. Edwards} | ||
