 |
|
I have studied plans page 6-WLO-1 thoroughly, but there are a few of things I still can’t figure out. Perhaps someone who has recently completed the wing locker installation could help me.
§ The plans show the locker rear panel being positioned 440 mm back from the front spar, but I cannot tell from the plans what I should be measuring from and to – is it from the center of the spar cap to the front edge of the locker rear panel (i.e. rear side of the rib-mounted L-angles)? If so, does the thickness of the rear upper spar cap, the length of the top flange of the top spar cap angle, and the width of the spins on the hinge combine to make up the difference between this 440 mm measurement and the 410 mm length of the cover plate?
§ A note at the top middle of the page says to use shims .032” + .025” on top of piano hinge to raise the cover plate flush with the rear top skin. From the diagram, it looks like the front flange of the hinge is mounted under the top flange of the top spar cap angle, and the rear top skin lays on top of this same top spar cap angle flange. If this is true, then it seems that I would only need to shim the thickness of the top spar cap angle (.032”) to bring the cover plate up flush with the top skin. Or am I supposed to also shim the top rear skin up off of the top spar cap angle with .025”, so that it matches the “height” of the top rear skin on the sides and rear of the locker opening where the .025” dzus strips have been inserted between the ribs / locker rear panel L-angle and the top rear skin?
§ The top left diagram for the cover plate (6WLO1-1) shows the Dzus corner fastener holes positioned 25mm from the sidse of the cover plate. Since the side Dzus strips are 20mm wide, this would put the center of the Dzus holes only 5mm in from the edges of the rear Dzus strip. Will this result in an inadequate edge distance for these holes?
I hope these questions make sense. Any help would be appreciated.

The hinge goes under the spar cap. I measured from the centre of the acutal spar , then the height of the wing lock rear panel fits .
I have just finished the right wing lock , my first and the shimming strips worked out perfect.
