Load test passed. Several problems encountered, the 3 hinges did not line up after riveting, so I eliminated the middle one. I checked the stress but the hole where it was needs to be patched. One problem with using a tractor for a fixture base is the rubber tires move when the weight is added. I ended up having to jack up the near axle to get the tail clear of the table.
The rudder was tested first with the stabilizer spar blocked. The all the rest of the weight was added, and the tractor jacked up until there was light under the tip.
The weight was 201 lb total with 83 lb on the rudder. 12 lb/ft sq. minimum limit load.
The distribution was approximately as page 28 Fig 1-XII Faa Basic Glider Criteria. The revised vertical tail with 4 attach fittings is 7.23 Lb.. The original wood one is reported to be 5 lb. and I do not know if that includes fittings. It is not as bad as all that because the original had a large wrench bonded to the boom at the tail for weight and balance.
