Referring to N.Scheme 2424, I have discussed this matter with Da.{Bernard Day - Chassis Design} who informs me that we are going to adopt the Bijur principle instead of the Bowen. This will probably affect most of the work, and there is no object in pushing this forward for the present. For Da{Bernard Day - Chassis Design}'s information, I would like to state definitely we prefer hard drawn brass out of the three alternatives. Steel tubes cannot be prevented from rusting, copper cannot be made hard enough. Hard drawn brass drawn to the same degree of hardness, and tempered, which Mr.Bijur has found suitable, is undoubtedly the right material. It is non-corrodible, can be sufficiently hard drawn without going too far, and running into season cracking dangers, to make its reliability practically 100%. We will obtain a number of samples of brass tube from America, and from them define the necessary hard drawing. BY.{R.W. Bailey - Chief Engineer} | ||
