Vickers} Rm{William Robotham - Chief Engineer}/AFM{Anthony F. Martindale}2/R.4.10.37. P.III BRAKE DRUMS. With reference to the section of P.III brake drum handed to you on Monday, which section has the pressed steel end plate cast solid with the rubbing portion of the drum, we want to get a set of such drums running on a P.III. We must be sure that using existing end plates for the test we have enough room for the cast iron on each side of it without causing fouls. Additional holes in the end plate are necessary to get adequate keying, and these may with advantage run out of the edge of the plate. In view of the satisfactory nature of the sample, it is proposed to design all future iron drums in this manner, subject to the further tests being satisfactory. We should like the drawings as soon as possible, so that RHC{R. H. Coverley - Production Engineer}/Vs{J. Vickers} can get moving. Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} | ||
