| DRB AL RIVETS Wor{Arthur Wormald - General Works Manager}/Hy{Tom Haldenby - Plant Engineer} (CJ.R. Hy.{Tom Haldenby - Plant Engineer} Ns.{Norman Scott}) Rivets must contact drum for temp conduction to straps. Copper ones squeak. & do not wear down enough. Have used a few alum rivets. & to date have'nt come to any harm. !! Propose to continue. R seems happy about it. J 'Wide straps no effect at hand. Daimler ride. Brake also does more on N. Side, so Radley's car seems to be something in the phenomenon. Lower leverage plenty low enough now. R's memo B5/B, 21-8-14. 1/4" Ferodo on order wide. other work all proceeding. (2-9-14) R to Wor{Arthur Wormald - General Works Manager}/mer. CJ. Na.{Mr Nadin} By Hy{Tom Haldenby - Plant Engineer} We are now interested in 1) 1/4" Ferodo. up to 6) (5-9-14) Hm{Capt. W. Hallam - Head Repairs} (Billy Halsean) Re Cars at the Front. Asks about ferodo. What about 50%/off? C/ Ferodo? Brogden (8-9-14) Urgent mods for cars OHMS. B to CJ "Cars at the Front. Brakes". We cannot help until we change drums. Have driven 5 & NA{Mr Nadin} many hundreds of miles lately at a v.{VIENNA} high speed, considerable use of brakes - 9 in v pleasant with it. Conversion of Std cars on trial. can be done in a few hrs with a vice (pail not needed). Suggests requisiting of mat'l at once. a/c contact 1 Wor.{Arthur Wormald - General Works Manager} CJ 14-9-14 (11-9-14) How much? Retraction. A(?) Wor{Arthur Wormald - General Works Manager}/Mer Is it proposed to change over brakes on all customer cars or drill new drums? [to get 1/2" extra Ferodo.] simply be fitted & new chassis up? as they come thro'? B to Wor.{Arthur Wormald - General Works Manager} By telup. No. [Rem ampled at Derby] By letter (8-10-14) Wor{Arthur Wormald - General Works Manager}/Mer (TC). 5,000 miles on Mr EG. Gainsfords (9 AB) exc. poor mileage for set of liner. Suggested NC for renewals. Is it policy(?) to select this & push for N.E. of low mileage. Discussed with EP.{G. Eric Platford - Chief Quality Engineer} suggest 8,000 miles. At price stated. & D's sheet this after 10 miles i.d. which not a figure to be proud of & a more reasonable as current instance. Problem in getting forgings - 4 weeks delivery - pressure of war work. (19-10-14) NO MORE EARLY TYPE BRAKE WORK Wor{Arthur Wormald - General Works Manager} & Mr Swift (fumptious old Harry) on 27-10-14 No Alum must any more present brake pull matt of be m/c'd or fitted on new car after that week. If must Looked on that current brake work is for use in testing only. (27-10-14) CJ Wor{Arthur Wormald - General Works Manager}/Mer (tc) Ref Mr Williamson's chassis extract from letter of 7-11-14. 'I'm perfectly satisfied with the brakes on my car & cannot say how these would seem well to me now. I've not tried one 1 yr latest chassis fitted with all brakes on India R'side wheels but would rather fancy. This may induce skidding under certain conditions. 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. (13-11-14) | ||
