| To EHC. x106 Hs{Lord Ernest Hives - Chair}/AFM.{Anthony F. Martindale}3/KW.18.7.35. Composite Bentley Brake Drum with Helical Ribs. We are having trouble with Bentley rear brakes, as there is at present insufficient cooling. The drum with sheet metal fan blades welded on, that you made for us recently, is a great improvement in this respect, and therefore we have incorporated this idea in the aluminium-steel composite drum detailed on Hs.{Lord Ernest Hives - Chair}2069. Will you please make one N.S. drum and end plate to this drawing. The steel used should be "Nitralloy" (not Vickers Durmo or other similar steel), and the aluminium a forging of RR-59. The end plate should be "Nitralloy". Hs{Lord Ernest Hives - Chair}/A.P.Martindale. | ||
