A view of the underside of the load beam showing the EMT pivot tube and the arrangement of the two hinge halves in the jig. Incidentally, the workbench that was used for the test was used by Corky Corbett to assemble the fuselage sides of his second Air Camper, NX42CC, and has traveled nearly 3000 miles from Shreveport, LA to San Antonio, TX and then to Medford, OR.
The test rig under load. The load beam is just about to touch the edge of the bench and the pail could hold no more sand, so the test was stopped here and the load was weighed. The load beam is clearly deflecting and the workbench made a few creaking complaints as the load had been added, but nothing broke or failed. The load at this point was determined to be just over 121 lbs., which means that the hinges were bearing over 900 lbs. of load. This is almost 30% more than the hinge that Vi Kapler load tested to failure, so the test was discontinued and I called it good enough.
I disassembled the test rig and inspected all components. The only apparent change was plastic deformation of the base of the test article as seen above. No such deformation was noted in the test article that Vi sent me from his load test; see image below of Vi's test article and his handwritten notes.
