| -2- and its effect is very noticeable and gives the car a feeling of power in picking up. I particularly noticed that although at the vibratory speeds the car in general seemed to be subject to a very severe vibration, yet the floorboards were perfectly still and the vibrations were not transmitted to the feet. I think the method of fitting the floorboards and possibly the body, should be very carefully investigated to find out in what way the Argyll Co. have isolated these parts so effectively. I also suggest that it is of great importance to run vibration tests with this engine on the rig that is now being set up in the Experimental Department. The engine should be run in various stages of completeness, that is - (1) Complete. (2) With pistons and con rods but with valves. (3) Without valves but with pistons and con rods etc. It may also be necessary if the crank is out of balance to replace this part by a plain shaft with gears attached for running the valve gear alone. Although I understand that the application of the brakes required considerable pressure yet this is the most pleasant car I have been on for brake application, from the point of view of a passenger; there is not the slightest [Handwritten in left margin]: When met report Very note [Handwritten in right margin]: sloanas Query correct | ||
