| TO BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} c. to GJ. c. to HS.{Lord Ernest Hives - Chair} GOS: 11. RADIUS RODS FOR FRONT AXLE. X4263 We send you herewith N.sch.1426. shewing the bracket for the rear end of the radius rods and revised ball joint which Mr. Royce wishes to take the place of that shewn on N.sch.1387. Mr. Royce would like you not to make N.sch.1387 at all. We have shewn 2 alternative schemes on N.sch. 1426, in one of which the pillar and connecting rod are solid forgings, and in the other they are built up by brazing. We should like you to tell us which of these 2 you prefer from a manufacturing point of view. As far as we are concerned we like the solid one, but are prepared to accept the built up one if you say it is definitely cheaper. It will be noticed that we have combined the previous 2 positions for B. and D.{John DeLooze - Company Secretary} into one intermediate between the two. The drawing is not quite to scale in this dimension and we should like you to determine it yourselves. Mr. Royce wishes to use the cross steering tube joint if possible exactly the same at the front end of the radius rod, and we should be glad if you would set this out. Mr. Royce now thinks that there should be no springs in the steering system at all, and in consequence the springs in the rear end of the side steering tube are eliminated and a joint exactly similar to the front end - with the exception of the lubrication - is used. We think the lubricator can be immediately under the ball joint pointing vertically downwards, and we should like you to set this out also. The ball joint at the rear end of the radius rod being novel we think ought to be pretty thoroughly tested before it is gone ahead with in any quantities. DA.{Bernard Day - Chassis Design} | ||
