Brian, Dave, help!

I can't seem to get this adjusted. If I leave the nuts slightly loose
there is zero friction in the aileron action.
If I tighten either the front or rear ball joint
nuts noticeable  friction is added to the control.

If this is described in the plans what page number?

BTW I changed Mike's bracket as I did not feel safe
with just a non locking jam nut on there with no
threads showing.

Well, i can't quite understand the situation from the pictures, but I
can say this, there should be no friction in the system from any of
those brackets, and the nuts should be secure.  Maybe missing a washer
or two?  It should be in the plans, though very occasionally you must do
things different than called out in the plans.

Re-reading your post, if I understand your problem correctly, there is
friction when you roll the ailerons. Those ball joint ends should stand
proud of the bodies of the ball joints, so it is not the bodies of the
ball joints that are causing friction against the brackets- it is the
ball joints themselves that might be sticking in the body of the ball
joint. Check the ball joints themselves for stickiness. I dimly recall a
method of unsticking them that involved rapping  them with a hammer
using surgical precision, but I don't recall the exact method. I'll try
to find a reference and get back to you. IIRC it was printed in an old
edition of "The RViator".

They were not sticking. For some strange reason the bracket wanted
to be 95 degrees relative to the spar and not 90 degrees.
The bottom forward edge of the ball joint was probably rubbing
on the control column bracket. Tilting the ball joint forward
solved the problem.
