We must test out shock absorbers in magnesium, also levers and pistons lightened to the standard maximum pressure of 250 lbs. instead of the 400 lbs. ball pin load at present worked to. Cannot the cast-iron ones be made in a lighter alloy ? We should get a set of lighter road springs on the bump. We should get statistics to show that the stress at which we are running the Phantom and 20/25 front road springs has caused us no trouble in the way of failures. We should get a Peregrine steering with the strengthened cross shaft on the bump as soon as possible. Stedman. We think our fan is unnecessarily heavy. We consider that it is extravagant having a cast bottom radiator tank, and that we should get one made up in sheet metal and test it. We ought to consider how we can lighten the radiator shutters. Now that the radiator is going to be 25% lighter than it was, cannot we lighten the supports ? The radiator cap seems to us to be unnecessarily heavy. Cannot we reduce the capacity of the top tank now that we carry less water ? Are the overflow pipes unnecessarily heavy ? Hardy. We should follow up the use of the Peregrine servo in conjunction with the Girling brakes. Also calculate how much we could reduce the weight of the Servo if we had a chain drive which would permit operating over 360° movement instead of the present small arc. | ||
