| To Mr. [obscured]. From R.{Sir Henry Royce} Copy to [obscured] [obscured distribution list] (For the attention of R.A. & OY.) ORIGINAL. RECEIVED X.3054 RE EXTENSION TEST PIECES. Regarding Mr. Nadin's suggestion (NA{Mr Nadin}3/S21120) that test pieces should be left on the following parts :- Rear Axle Tubes. Connecting Rods. Axle Pivots. I quite agree that any important part should have a test piece left upon it. The pieces of most importance are those in connection with the front axle, and the steering gear, of less importance is the back axle, and still less such parts as connecting rods, which would only mean a breakdown without risking anyone's neck. You will remember that we first introduced in our early automobile days, that every steering ball joint which was case hardened should have a test piece which was broken off after case hardening. This, and similar parts, such as that of the stub axle seem to be of the utmost importance, and should not at any time be neglected. The next piece, one would think, should be the steering levers, and I shall be glad if you will send me a list of the frequencies of taking tests so that we can make it uniform in both America and in England.
