Herewith E.CD.990, a suggestion for a dynamo drive giving increased flexibility without end loading the dynamo bearing, and without using excessively soft rubbers. Should any interest develop in this, the driving piece could, if considered advisable, be made an aluminium die casting, somewhat thickened in places, as compared with the forging. For the moment, we wish the scheme to be merely filed for reference, in case the question should arise in future. DA.{Bernard Day - Chassis Design} | ||
