Back to my wood wing build update. It's another series of pictures, and we're picking up exactly where we left off a few days ago.
(My earlier post on this wood rib wing topic may be found here).
|Clamping on the anti warp anti crush tubing.|
|Clamps removed showing anti crush anti warp structure.|
|Gluing 4 inch wood gussets, 1/4" thickness, to ribs.|
|Glue up for gussets, close up.|
|Trailing edge riveted in place.|
|Slot cut on some ribs to fit flaperon hard points.|
|Flaperon attachment right angle material, with spacing for 3/16" rivet holes shown.|
|Flaperon attachment clamped in place, showing 1/4" overhang at rear of trailing edge.|
|Flaperon cable post, showing how it has to be cut and drilled.|
|Use 3/16" rivets and large backing washers.|
|Post bolted in place using AN3 bolts, cut down washers, spacers as necessary. This post is still backwards.|
|Right angle with two 1/8" rivet holes each side. 3/4" x 3/4 x 3/4, or larger.|
|Rivet four right angle braces in place. (Two at each end of rib; both end ribs.)|
|Complete anti-crush anti-warp structure in place on end rib.|
|Hardpoints for anti-sail tubes will be riveted on spars. Exact placement determined by tubing lengths.|
|Anti-sail hardpoint riveted in place.|
|Anti-sail tubing layout. 2', 4', 3', 3'1", 2' lengths from near to far.|
|Anti-sail hardpoint with AN3 bolts. Use appropriate washers to ensure clearance.|
|Lift strut machined attachment, riveted in place.|
|Trim plates riveted in place.|
|Another view of trim plates. Note spacing washers under plates/rivets to ensure straight / parallel trim plates.|
|Pitot tube installation using 1/4" aluminum tubing and grommets.|
|Routing of pitot tubing line.|
|Another view of pitot tubing attachment. Pitot tube may extend and retract.|
|Trailing edge material butt joint. Sweet and simple.|
a) Never did show the installation of the jury strut fittings. I'll add that.
b) Didn't show the wooden structure being painted with spar lacquer.
c) Didn't show the fabric covering.
