Steering Developing Stiff and test of weaker buffer springs. During a test of about 250 miles recently taken on a new chassis on test, 43-TC, by Mr. Wyer he reports as follows:- "I ran the above 234 miles for the purpose of checking the new type of steering, and it does get tacky after about 50 miles run, and the return disappears on corners, due I would say to the oil getting very thin and the whole box etc. becoming very hot, and the viscosity of the oil changing so much, but it seems to remain at that, and does not get much worse say at 100 miles. The steering when starting out was quite good and free. Before the return journey I fitted to the side steering tube the set of four lighter springs and these were an advantage from the tacky steering point of view. It seemed to take 75 miles to get to the same position as the 50 miles with the standard springs. I did not experience any disadvantage with the lighter springs, and was quite free from wobble at average touring speeds; high speeds were not possible, too much traffic." EP.{G.
