| To Da.{Bernard Day - Chassis Design} From Hs{Lord Ernest Hives - Chair}/AJL. c. to By.{R.W. Bailey - Chief Engineer} Hs{Lord Ernest Hives - Chair}/AJL.1/MJ.221.30. PHANTOM 11 CENTRE LAMP BRACKET. x7800 Re. Centre Lamp Bracket D.72404 (stiffer section and thicker gauge than standard). We have tested out one of the above brackets using a Grebel spot lamp. There is less dithering than with the standard bracket, but still it is insufficiently stiff. To make a reasonably stiff job it will be necessary for the bracket to be as stiff again as the bracket D.72404 is stiffer than the standard one. Hs{Lord Ernest Hives - Chair}/AJL. | ||
