| CONTD :- -2- in excellent condition. We shall continue running them. The results so far prove that the design of the rod is satisfactory, it is certain the the design does not account for the rods breaking in one or two hrs. running. The failures must be due to flaws in material. It appears as though we are right in striving to get a steel which is consistent and easy to handle rather than one which gives exceptionally good results on test pieces. The rods were made to the original drawings, not with the increased thickness of web. EH. | ||
