Assembling the Left Aileron

click We’re getting close to having a completed aileron! I was able to fully complete the assembly and drilling of the left aileron tonight, and its parts are now ready for deburring, edge finishing, and priming. I will hold off on that until I have the right aileron done and do the all the parts in one big batch. For tonight, I started off by clecoing the A-802PP leading edge skin and the A-801-PP trailing edge skins to the spar and then clecoing the A-705-R/L end ribs into the trailing edge skin. Once I had that done, I inserted the 1/2″ galavanized water pipe (A-409) into the leading edge skin, and then clecoed the A-704-L/R nose ribs into place to help hold the A-409 counterbalance. Once I had every thing assembled, I double checked for alignment.

It’s simple, robust, and cheap, all principles that Van’s uses in their “Total Performance” moniker. Thankfully, Van’s ships this pipe in the wing kit, and its precut to length! Once I had made sure everything was still in alignment, I went ahead and match drilled everything to their respective hole sizes. The normal process is I cleco every other hole, and then match drill the empty holes to their correct size, then move the clecos over by one hole and drill the rest of the holes. I like to use a lot of clecos on the ends to help hold everything secure, so I have to make sure I remove them, drill and then replace them afterwards. I am also going to use a edge roller / former to break the edge of the leading edge skins before I dimple. This will give the skins a nice flat joint when I rivet them.

Next up was to drill the holes into the A-409 counterbalance / water pipe using the pre-punched holes in the skin as a guide. HERE’S where I think I may have messed up. Take a look at the photo below:

This is the first time I drilled this counterbalance, and somehow my drill walked and chewed away at my skin before it made a pilot hole in the counterbalance beneath. It’s zoomed in in that photo, so it looks bad, heres a ruler for scale:

Which worked out wonderfully on all the rest of the holes in the counterbalance. BUT, I am concerned about this. I’m going to give Van’s a call in the morning and send them the photos to get their opinion on it. Worst case scenario is I have to buy a new leading edge skin and A-409 water pipe, best case is that they tell me to use a bigger hole and rivet (which would be super easy to do). I’ll update this post when I find something out.

The plans has us remove the trailing edge skins, and re-cleco the leading edge back onto the spar for alignment, and then use a long 1/8″ drill bit to get to the last two holes we need to drill. We go into one of the existing holes for the A-704 nose ribs on the bottom and then drill the hole into the counterbalance using the hole in the flange as a guide. Like this:

For here, I disassembled everything, and put the parts on the shelf until I get time to deburr, finish the edges and clean them up for priming. Thats it for tonights session, I will do the right aileron in the same fashion tomorrow. Hopefully after I speak with Van’s I’ll get good news that my mess-up is fixable. I am just glad that it happened on a part thats relatively easy to replace if need be! Especially since I haven’t spent the man hours prepping and priming it yet! Heres all the photos from tonight:
