MO/KF YOUR REF. 29th December 1937. Mr. Grylls, Rolls Royce Limited, DERBY. Dear Grylls, Replying to Leslie's of December 22nd and yours of December 24th. Shock Spindles. I attach a couple of prints showing knurled spindle and lever with round hole. Any hard spindle will push into any heat treated lever and make a decent joint in this way. Even front shock absorber arms on wishbone suspensions are attached in this fashion. Crash testing indicates they are safe. Spring Covers. If you are going to cover springs, sheet metal covers with canvas linings as now used on 25 hp Vauxhall (1938 model) are the best way to do it. Better yet is not to cover or lubricate the springs but to use interleaves of prepared paper like Cadillac. We are trying hard to develop this here. Skid Pad results. I have the most conscientious objections to your skid pad charts. Charts showing one isolated thing like the steering angle for example are of very little use because they do not contain the explanation for the observed steering angle. I attach two prints of Oldsmobile 6 skid pad results which will show what I mean. These are my only copies so I would like them returned. | ||
