| X1023 To H1. from Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}4/KW.20.8.36. Wilmot-Breeden Bumper Bar Weights. These weights are deforming in service. We do not want to make a complicated scheme to make them hold their shape. We suggest that a simpler scheme would be to increase the hardness of the lead by making an alloy to take its place. For obvious reasons the cost of the alloy is important. We shall be glad to know whether you can recommend something which would do the job economically. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
