Next I attached the wheel pivot arm and wheel next. There is a nut that goes on the bottom threads of the gear leg. You tighten the nut until it take 26 pounds of force to move the pivot arm at the axle attach point.  I bought a 50 pound digital fish scale to measure it with.

The last two pictures show the gear legs attached to the spar with several support pieces. It is a nice set of well engineered parts that hold it all together.
