| DRB AL RIVERS (117) Wor{Arthur Wormald - General Works Manager}/Hy{Tom Haldenby - Plant Engineer} (CJ.R. Hy.{Tom Haldenby - Plant Engineer}Na.{Mr Nadin}) Rivets must contact drum for temp conduction to stop squeak. Copper ones & a few alum rivets do not wear down rivets & to date haven't come to any harm. I propose to continue. Radley seems happy about it. 2" wide traps not yet to hand. Daimler side brake also does more on N. side on Radley's car. Seems to be something in this phenomenon. Lower leverage R.{Sir Henry Royce}'s memo plenty low enough now. R to Wor{Arthur Wormald - General Works Manager}/B 21-8-14. 1/4" Ferodo on order. mike other work/all proceeding. (118) R to Wor{Arthur Wormald - General Works Manager} (mer. C.J. Na.{Mr Nadin} ByHy) We are now interested in 1) up to 6) 5-9-14 (119) Hm{Capt. W. Hallam - Head Repairs} (Billy Hives) Re Cam at the Front. 8-9-14 Cl Re Cams? about Ferodo. What about 50%/50%? (120) B & CJ Brakes at the Front. Brakes. By says 11-9-14. Urgent for mods for OHMS cars. We cannot help until we change drums. 58 NA{Mr Nadin} has done many hundreds of miles lately at a v.{VIENNA} high speed, considerably was of brake - I'm v.{VIENNA} pleased. Conversion of Std done in a few hrs with a vice (pail not needed). Can do requisitions 1 matl/l at once. Suggest CJ to Hm.{Capt. W. Hallam - Head Repairs} Arrange a/c? contact Wor.{Arthur Wormald - General Works Manager} CJ 14-9-14. (121) A(?) Wor{Arthur Wormald - General Works Manager}/Mer "Is it proposed to change over on all customer cars or will new drums/to get better retractor? simply be fitted to new chassis as they come thro?" BY to Wor.{Arthur Wormald - General Works Manager} BY.{R.W. Bailey - Chief Engineer} Ran super at little Kudo. 8-10-14 (122) Wor{Arthur Wormald - General Works Manager}/Mer (TC). 5,000 miles (on bus E.G.) 19-10-14 (123) Gainsfords (19 AB) exc. poor mileage for set of liner. also Policy(?) to select some for N.C. for renewing at low mileage. Discussed with EP.{G. Eric Platford - Chief Quality Engineer} suggest 8,000 miles. At price stated in D's sheet this a/c offer 10 miles 1d which not a figure to be proud of in a more reasonable co. current instance. Problem of getting forgings. 4 weeks delivery - pressure of war work. (124) NO MORE EARLY TYPE BRAKE WORK! Wor{Arthur Wormald - General Works Manager} to Mr Swift (Fumptious Std Harry) on 27-10-14. No a/p must any more present brakes pull matt'l. No m/o/d or fitted on new car after this week. Must be looked on that current brake work is for use in testing only. (125) CJ Wor{Arthur Wormald - General Works Manager}/Mer (tc) of Mr Williamson's chassis 13-11-14. extract from letter of 7-11-14. I'm perfectly satisfied with the brakes on my car & cannot say they have ever been well up to improved. I've no further use for them, all brakes on Front & Back wheels but would rather fancy this may induce skidding under certain condition. I think the latest method is a great improvement constructionally as it relieves the transmission parts of the braking wear & tear. Mr Williamson's car will of course be fitted with the v latest type of DRB containing all the recent mods & improvements. | ||
