| 306 To BY.{R.W. Bailey - Chief Engineer} Copy to H.Da.{Bernard Day - Chassis Design} Hs{Lord Ernest Hives - Chair}/Nor. Hs{Lord Ernest Hives - Chair}/Martindale. E/Ev.{Ivan Evernden - coachwork}1/IR.30.9.36. Phantom III - Front Brakes. As mentioned in our E/Ev.{Ivan Evernden - coachwork}6/MN.29.9.36, we now send to you a modified front brake cam of radius .6". The cam as drawn has 50 thou. clearance between its maximum diameter and the brake drum. In order to maintain the same ratio between front and rear braking it will be necessary to shorten the intermediate lever to the rear brakes to 1.575". We would be glad if you would arrange to do this. Ev.{Ivan Evernden - coachwork} Att: N.Sch.4918. | ||
