Such a phenomenon could shear the vertical thimbles at a point just below the thermal blocks. Equipment is to be developed for measuring any eccentricity between the rod guide and a section of the thimble located just below the end of the guide. Jacking tests using forces up to 4000 lbs. on gun-barrels which show binding have demonstrated that binding is still present at these high forces. It was recommended that no further jacking tests be performed on gun-barrels which are known to exhibit binding. Rupture tests on Tube 4082-B caused failure of the rear Van Stone joint after the tube had been stretched {1/2} inch. The amount of tube stretch before failure of the flames will probably be affected primarily by corrosion of the flange and, for the same reason, …
