I am really, really close to finishing this project!!!

But when reassembling the elevators last weekend I noticed some light
friction on the right elevator.  The friction doesn't emanate from
fiberglass contact at the elevator/horizontal stab line - there is no
touching along the upper or lower "seam".

I think the rubbing may be coming from metal to metal contact at the
innermost hinge bracket on the right side of the plane.  The bearing bracket
that is attached to the horizontal stab is NOT perfectly aligned - it is
"cockeyed".  (I didn't build this part - a "professional" did).  It looks
like the aluminum bracket that holds the bearing may be contacting one of
the aluminum brackets on the elevator.

The contact is very minimal, but with just the left side elevator attached
to the control systems the elevator drops instantly to the down position
(almost with a soft "bang").  But when I attach the right side it almost
holds its position, or slowly sinks to the down position.

So my question is - how should I fix this?
1. File the aluminum bracket that holds the bearing a tiny amount - just at
the rearmost part of the aluminum
2. File the aluminum bracket on the elevator (I don't like this idea because
it would be filed sort of in the middle of the bracket, and is bearing some
load
3. Remove the bearing bracket from the horiz stab and round out one of the
holes a small amount such that the bracket can be rotated a few degrees
(correcting the "cockeye" problem).

The good news is that the "hinge" is a bearing, allowing a small amount
misalignment
The bad news is that I don't think it is possible to move the holes in the
horiz stab

Any other thoughts?  

Thanks,

Matt
