| X.980 To Hs.{Lord Ernest Hives - Chair} from DA.{Bernard Day - Chassis Design} DA{Bernard Day - Chassis Design}1/MS31.1.24. RE. TURNING CIRCLES. X.980 Thank you for your Hs{Lord Ernest Hives - Chair}1/LG29.1.24. We presume that these good circles and locks are actually obtained on production chassis. The reason why we are interested in knowing exactly when is being obtained now is because it is evident it is going to be difficult to equal it on the front wheel brakes chassis on account of the method of operating the brakes. We believe however that we can get 35° and 38° respectively. Of course it may appear that we can get a little more than this by touching up some of the pieces, but in any case it is going to be almost impossible to get 42° lock. We hope that as soon as an axle with the modified position of the pull off rods to give increased lock is available, that we can have the turning circles of this.
