The cable eye is drilled but then rounded/chamfered (kind of like an
overly deep deburred hole) so there are no sharp edges where the cable
and thimble pass through. And of course you have to match a right hand
thread with a left hand thread for opposite ends. It was a head
scratcher and I think I ended up with a few extra parts before I got it
right. I assume the turnbuckle size is matched to the cable diameter for
strength.
The light bulb finally went on yesterday in regards to aileron trim.
When I'm flying solo I have a noticeably heavy left wing even with extra
gas in the right tank. The thing is that if I hold the flaperons
perfectly faired with the wing, the plane flies straight and true. If I
let go of the stick the right aileron drops a bit from faired and the
right wing rises. Finally realized that if I close the throttle and let
go of the stick, the plane again flies straight and true again. I'll
bet anyone out there with a couterclockwise rotating prop (seen from the
cockpit) has a heavy right wing... Some of it may be torque but I think
this is a characteristic of flaperons where the propwash helix is
deflecting the flap(eron) near the fuselage. My prop rotates the
American way - clockwise as seen from the cockpit.

Going to order two turnbuckle assemblies today. Thought it would be an easy
process <sigh>.
I'm looking on-line at Aircraft Spruce & Wicks (better drawings) at the
admittedly bewildering variety of turnbuckle assemblies and part #'s.

Hopefully someone can save me a whole lot of heavy-duty head scratching.
These will be used for my rudder cables.
. Since turnbuckles come in a variety of strength ratings, how
strong is strong enough for the rudder cable assembly
. When would one use an AN-165 pin eye versus an AN-170 Cable-Eye
versus an AN-161 Turnbuckle Fork?
. What are the pro/cons of simply attaching the cable with a thimble
through the eyebolt of the turnbuckle (e.g. AN-170 cable eye) versus using
an AN-161 turnbuckle fork on one end
. Will an AN-111-4 cable bushing will fit between the tines of an
AN-161 turnbuckle fork?
Geesh, science project <grin>
Thank you for your input!
