The job was now ready forblocking up, and this was done by leav-ing the top half hanging on the chainblocks apd shoring from the wall toprevent moving. The welding then took high-pressure crank pin was »found tobe slightly out of true, a fact which gaveconsiderable trouble in the running. Thewelding itself was a strong and wellfinished job, and as far as it was con-cerned the shaft was as good as accompanying illustration (on page16) shows a broken piston follower plate,which belonged to the auxiliary hydrau-. FIG place. The actual time for preheating,forming the V and weeding, not includ-ing the setting up, was five hours. Thenext job was putting the shaft in thelathe, and when this was done it wasfound to be out of true. The torch wasapplied to the crank pin of the welded D
