Absent:- Rm{William Robotham - Chief Engineer}/VJH. Rm{William Robotham - Chief Engineer}/St.{Capt. P. R. Strong} 1. BRAKES. Rm{William Robotham - Chief Engineer}/MGR. has prepared a brake wear chart which should be kept up to date. A set of light alloy drums has now been fitted to 9.S.V. A new type of temperature resisting liner is being fitted to the rear of 4.S.30 and also 30.G.VII and the results will be reported at the next meeting. Experiments will proceed with regard to servo judders on J.S.30 and it is thought that star springs may eventually be necessary to cure the judders. Four more light alloy drums will be instructed as soon as those at present made have covered a reasonable mileage without trouble. The designs of combined drum and hub have been completed for both standard and Buick pivot pin assemblies. These should be detailed forthwith and a pair for the standard pivot be completed and fitted to an experimental car. Ev{Ivan Evernden - coachwork}/JD.{J. Draper - Frames} still has to look into the question of wider brake drums on the back, which he will combine with the light alloy design. 2. SPRING & TYRES. There appears to be some doubt as to why these are being run. It was suggested that the most useful application would be to lubricate thoroughly and inspect the springs every 3000 miles, to see at what interval they would have to be serviced to keep in good condition without prejudice to the ride of the car. It was decided that Bastow would take up the question of getting a cheap version of fully lubricated springs after the war. 3. STEERING & PIVOTS. These were NOT YET FINISHED. | ||
