The tailwheel support tube was drilled at one end to fit the 5/16" bolt. This was done twice because the earlier hole was not in line to each other. The end tube was then cut and another hole was again drill and this time it match one another. Using a 3/4" drill bit, a hole was then drilled to the torque tube washer, the trim plate and the torque tube horn. The holes were then filed to smoothen the corners. Also, took time to smoothen the shape of paired items so that they have the same shape.
