As the title says, spent about an hour cleaning up some fittings and bolts and nuts. Cleaned up and deburred end of aileron where torque tube connects. Again, the workmanship and corresponding complexity is impressive. Why a universal joint is required on the connector to the aileron torque tube is beyond me. It's part of the novelty of this plane. I suspect that the aileron end of the universal joint was dropped on the ground at some point. It required a bit of deburring for the ball joint to fit into the fingers. A bit of time with a fine file and some 600 grit sandpaper allows the assembly to come together. It's now beautifully smooth without any play in the rotation.
I took a picture of the spoiler system for interest sake and weighed the pieces of it. At least 15 lbs will be saved by not mounting the spoilers in the plane.
