| DRAFT. [Handwritten]: Circulated under Rm.{William Robotham - Chief Engineer}14/ET.16.5.41 1373 MINUTES OF TESTERS CONFERENCE, HELD ON MONDAY 5TH MAY 1941. Present: Rm.{William Robotham - Chief Engineer} Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation} Rm{William Robotham - Chief Engineer}/Wym.{G. Harold Whyman - Experimental Manager} Rm{William Robotham - Chief Engineer}/RC.{R. Childs} Rm{William Robotham - Chief Engineer}/TAS.{T. Allan Swinden} Rm{William Robotham - Chief Engineer}/Clm.{D.

Draper - Frames} Rm{William Robotham - Chief Engineer}/GB. Rm{William Robotham - Chief Engineer}/Fred Hallam. Absent: Rm{William Robotham - Chief Engineer}/FERH [Strikethrough]. Rm{William Robotham - Chief Engineer}/HH. 1. BRAKES. [Handwritten]: BRAKE WEAR Rm{William Robotham - Chief Engineer}/MHR.{M. H. Rigby} has prepared a/chart which should be kept up to date. A set of light alloy drums has now been fitted to 9.B.V. A new type of temperature resisting liner is being fitted to the rear of 4.B.50 and also 30.G.VII and the results will be reported at the next meeting. Experiments will proceed with regard to servo judders on 3.B.50 [Strikethrough] 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. [Handwritten]: PIVOT PIN ASSEMBLIES The designs of combined drum and hub have been completed for both Standard and Buick. These should be detailed forthwith and a pair for the Standard completed and fitted to an experimental CAR. [Handwritten]: PIVOT PIN 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 GAITERS. 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 5000 miles, to see at what interval they would have to be serviced to keep in good condition and, if there was any possibility, to do away with the bijur lubrication 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. 4. BODY MOUNTING. This experiment will go forward. 5. ALUMINIUM CAMWHEEL. The one that has been run on 9.B.V seems O.K. for durability. The next experiment will be an endurance run on the test bed. 6. AXLE. 30.G.VII has been fitted up with the simplified axle. 7. PROPELLOR SHAFT. There are several cars with propellor shaft periods. A test should be carried out to see if periods can be eliminated by means of jubilee clips and a report given at the next meeting. Rm{William Robotham - Chief Engineer}/Wym{G. Harold Whyman - Experimental Manager} reported that [Handwritten]: BALANCING RIG WAS nearly finished 8. 12 B.V GEARBOX BEARINGS. | ||
