| Incidentally, Chevrolet disapprove of the little bridges across the water jackets on EB-3778, but they may know nothing about it. Am inclined to think that the missing link on cylinder bore experiments is failure to find whether bores stay round and straight under load and temperature. Have a note to see Bryon Ellis at Cadillac about this at the first opportunity. Propellar Shafts Have now sent you notes on Mechanics practice with extension recommendation and print of Cadillac shaft and Spicer Toledo practice. If you will send me necessary dimensions and figures on loads, wheel size, axle ratio, engine torque, and low gear torque, also details of gearbox splines and pinion splines. I will get some propellar shafts made up for you and send them over. Can you get import licenses if I do? Timing Gears Are shipping you a cast aluminum timing gear off a Lincoln. Was round Fords yesterday with Drummond of National broach, L.W. Mix, and 2 men from British Purchasing Commission. The aluminum gears are quieter than resin-fabric gears, cost less, are cut for less money, live longer. They are barrel-shaved on a National Broach (Red Ring) shaver. You can see the shaving marks on the teeth. Are now on all trucks, all Lincolns, 50% of Ford passenger cars. Wills shortly supplant fabric entirely. Will make enquiries on the Morse chain. Have you watched it with a Stroboscope? Why not have me send you a "Strobotac". This gives enough white light to use in moderate daylight on a job like this. Geoff. Bastow knows about it although he has never seen the actual Strobotac. Spark Plugs Have now given you unprejudiced information straight from the horse's mouth on the American passenger car spark plug situation as revealed by Ethyl lab. Steering Am getting all the latest on ball nut steering from Walter Kull at Saginaw. | ||
