With reference to Hancock's report on the Wilmot-Breeden Bumper and the collapse of the lead weights, Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux}5/JAB.18.8.36. It appears to us that it might be possible to get over the trouble by adding a small quantity of antimony or some other element to the lead to make it harder, and that this might be more economical than making a complicated scheme to make the weights keep their shape. We are taking the matter up with Hl. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
