The tie rods were ordered earlier this week. Here you can see the simple but effective method for adjusting and measuring. The mock-up wire is simple mechanic's wire, and the adjustment bolts are from the local hardware store. The trick is to let the wires stretch over night before adjusting/measuring, otherwise, you'll be chasing adjustment back and forth as the wires move. The mock rigging process took only a few hours and was very simple. The wire lengths were identical left/right...a good sign of a squared airplane! Edit: we also made sure the wings were hovering over the table to protect them from falling to the floor if the wires broke over night.
