(1) G.W.H. will see that the Hardy Spicer propeller shaft, and the servo with the Hardy friction damper on the swinging arm, are fitted to B-56-BN{W.O. Bentley / Mr Barrington} before it goes on 15,000 miles test. Whyman will also give him a specification for an alternative exhaust system which is provided for this car. (2) G.W.H. will get careful performance figures for B-56-BN{W.O. Bentley / Mr Barrington} with the fully split skirt pistons in, and then change over to Aerolites and repeat the tests. (3) Dodd will obtain a Delco ignition governor which gives the final ignition advance curve required to maintain the performance on B-23-AE, and test it out. (4) Dodd will also check the effect of water temperature on detonation on B-23-AE. (5) G.W.H. will get the cut away starter motor bush fitted to B-56-BN{W.O. Bentley / Mr Barrington} before it starts 15,000 miles. (6) Whyman will carry out his exhaust tests on B-23-AE and 6-B-IV, which are now both available for this job. (7) Dodd will fit the 6" wheels with the large section tyres to 6-B-IV. (8) Martindale will confirm on J-B-IV that reducing the arc of embrace of the front shoes does eliminate the tendency to jagger, and having done this, we will instruct some shoes for the light alloy drums. | ||
