Enjoy!
See ya, Dave
Alignment suggestion: how about a simple sight gauge? A removable fixture sitting on top of the fuselage (maybe 1” pvc pipe attached to a FG saddle) which "fixes" two vertical “whiskers” aligning perpendicular to the fuselage center-line. These “whiskers” would be spaced as far apart as possible without interfering with walking out the wing. With the fixture on the fuselage top “sweet spot", just "gun sight" the whiskers while out at the tip until properly aligned with a reference point on your wing. Wing should then be positioned close enough to align dead on within the adjustable travel of the rigger base if needed. KISS rocks.
More important suggestion: the thought of lifting any wing tip and carrying its load to full extension while stepping over a mid-way pivot rigger is inviting a probable trip/fall/damaged wing and SCREAMS oh my aching back. With rigging aids becoming the norm and the linear actuators proving to be so helpful, pilots with bad backs and especially “bus” or “big bird” pilots need a dual purpose rigging aid. First it would serve as a “wingout” device; it would be used to capture wing tip handles and lift the wing tip so the wing could be rolled straight back to full extension. Once fully extended, the linear actuator would transfer the wing tip load to a purpose built tip stand. Once on the tip stand, the aid would be converted into the current wing cuff pivot rigger and manage the positioning and rotating of the wing until the wing root is seated into the fuselage. I think a dual purpose rigging aid could use the existing IMI or Enstroj (another well designed pivot rigger) actuated base and reengineered to offer easily interchanged “wingout” and pivoting wing cuff “heads” to handle all the lifting loads.
Proof of concept should develop an easy process which eliminates any lifting heavier than what is required to lift the trailer clamshell roof.
(Dave, please share the sight gauge idea with the ARCUS group.)
And ya’ll quit slinging cow piles at each other.
