Right Wing & Aileron Controls

I don't have pictures of most of the steps, but with Dad here, we hammered through the right wing and got the top skins, J stringers, aileron and flap brackets, and gap fairings riveted on. It feels great to finally have this wing caught up with the other one!  The fuel tank took a little bit of work to get it mounted to where it laid nicely against the other leading edge and spar, but after tweaking a few things (including squeezing some of the rear baffle rivets a little more so they wouldn't hit the spar), we got it mated nicely.  Something for me to keep in mind in the future is that it's easier to "set" the tanks in the right position by using the screws through the skin vs starting with the z bracket bolts.

We moved the right wing off of the stand and set it in the cradle alongside the left wing.



We tackled the aileron control rods next.  The large aluminum tubes that connect the sticks to the aileron bellcranks were cut to the required length, then we primed the inside by flooding it with rattle can primer.  We pulled a partially inflated balloon through the tube to help spread the gobs and gobs of primer down the length of the tube.  Each end of the control rods got drilled for 6 blind rivets and the threaded rod ends were riveted on.  Ultimately, the rod end bearings will thread into these and be attached to the fuselage controls and aileron brackets.

The aileron bellcrank to aileron pushrod was up next.  This is powder coated steel vs the aluminum of the larger pushrods.  The plans could make life a little easier by simply indicating the length the pipe needs to be cut to.  Not sure why they don't, but after checking and double checking we finally figured out the length and used a hacksaw for the cut.  These tubes are much smaller, so we simply poured some primer in them and sloshed it around until the insides were coated.  Next up will be drilling these and riveting on the rod ends.


We installed the aileron bellcranks onto the right and left wing spars next.  Not all of the bolts can be put in place permanently until the pushrods are primed and installed, but we put in the bolts we could and torqued them to spec.  All final torqued bolts got torque seal applied so I have an indicator of which ones have been completed.
